 Comp-Comz

COMP-TRACE EFFECT
(Syntax) A constraint on wh-movement. Notice first that long-distance wh-movement of complements and adjuncts is unaffected by whether the complement clause is headed by an overt complementizer or a silent one (indicated in the following examples by ø):

  1. [Which friends]i did they say {that, ø} they saw ti?
  2. [Which way]i did they say {that, ø} they would fix the leaky faucet ti?
 By contrast, long-distance movement of subjects is possible only with a silent complementizer. The presence of an overt complementizer immediately preceding the trace of wh-movement is ungrammatical; hence the name of the effect.
  1. [Which friends]i did they say ø ti saw them?
  2. *[Which friends]i did they say that ti saw them?
 There is some variation among English speakers with regard to the status of (4) (Sobin 1987). But even speakers who judge it to be acceptable report a Comp-trace effect in connection with movement out of indirect questions. | Beatrice Santorini and Anthony Kroch, 2007

COMPARATIVE ELLIPSIS

  1. (Syntax) A syntactic phenomenon in which elements of a sentence are omitted because they can be inferred from context, particularly within comparative constructions. It serves as a mechanism for linguistic economy, allowing speakers and writers to avoid unnecessary repetion while maintaining clarity and grammaticality.
     Ellipsis is a fundamental grammatical mechanism that enables speakers to omit certain linguistic elements when they are contextually inferable (Leech 2006). This process enhances linguistic efficiency by reducing redundancy while preserving meaning. One important type of ellipsis is comparative ellipsis, which occurs in comparative constructions where repeated components, often verb phrases or predicates, are left unexpressed. For example, in the sentence


    the predicate is tall is understood from the preceding clause and is therefore omitted.
     Comparative ellipsis allows sentences to remain concise without losing semantic clarity and is widely observed across various registers in English, including both spoken and written forms. While comparative ellipsis occurs in both British and American English (BrE and AmE), prior research indicates subtle yet significant differences between the two varieties.


     Additionally, AmE relies on do-support in many ellipsis contexts, a feature that distinguishes it from BrE. | Goncha Ahmadova, 2025
  2. (Syntax) Two construction-specific types of deletion processes have been claimed in the literature to co-determine comparative formation.


     | Winfried Lechner, 2008
  3. (Syntax) At least three rules have been taken to operate in comparatives:

    1. Comparative Deletion (CD), an obligatory rule that deletes the entire compared constituent under identity with the head of the comparative clause.
    2. Subdeletion, an obligatory rule that deletes only the quantifier-like element of the compared constituent under identity with the quantifier-like element in the head of the comparative clause.
    3. Comparative Ellipsis (CE), an optional rule that deletes material in the comparative clause that is outside the compared constituent, under identity with material in the matrix sentence in which the head of the comparative clause is embedded.

     These rules are exemplified below, where CD has applied in (1), Subdeletion has applied in (2), and both CD and CE have applied in (3).

    1. Mary wrote more books than John wrote φCD .
      (φCD = x many books)
    2. Mary wrote more books than John wrote φSub articles .
      (φSub = x many)
    3. Mary wrote more books than John φCE φCD .
      (φCE = wrote; φCD = x many books)

COMPARATIVE LINGUISTICS
(Diachronic) Previously known as comparative grammar or comparative philology. Used to study the relationships between two or more languages in order to reveal whether or not the languages have a common ancestor (Britannica n.d.). Comparative linguistics was mostly used during the 19th century in Europe as it was firstly initiated in 1786 by Sir William Jones who discovered that Sanskrit was related to Latin, German, and Greek.
 Robins (1975) wrote that comparative linguistics has a very important role in contributing to the understanding of the nature of how language works and the development (change) of languages in the world. In this regard, the main task of comparative linguistics is to analyze and provide an explanation of the nature of language change. In general, the nature of language (1) has a structure (synchronic dimension) and (2) is always changing (diachronic dimension). | Wulan Yulianita, Yasa Nur Malina Ruminda, 2023

COMPARATIVE PSEUDOGAPPING
(Examples)
 ○ The predominance of comparative clauses, which reveals as a general characteristic of pseudogapping in Miller's (2014) corpus study and Hoeksema's (2006) experimental study, does have the effect of strengthening structural parallelism between the antecedent and the clause hosting a remnant. | Joanna Nykiel, 2025
 ○ Miller (2014) showed that comparative pseudogapping is a very frequent construction, and our results further confirm that it is highly acceptable as well. By contrast, Hoeksema's findings on non-comparative pseudogapping suggest that it is degraded in acceptability relative to comparative pseudogapping. | Till Poppels and Philip Miller, 2023
 ○ Levin (1979/1986) notes that a wider range of constituents seem to appear as remnants in cases of pseudogapping in comparatives. For instance, APs, VPs and PP complements to nominal arguments may occur as comparative pseudogapping remnants only; they are ungrammatical as remnants in "regular" pseudogapping in coordination.

  1. a. I probably feel more jubilant than you do relieved.
    b. * You probably just feel relieved, but I do jubilant.
  2. a. Rab felt more comfortable dancing than he did singing.
    b. * Rab felt comfortable dancing, but Bill did singing.
  3. a. Rab bought more pictures of his dog than he did of his cat.
    b. * Rab bought pictures of his dog, and Bill did of his cat.

COMPARATIVE QUALITATIVE BINOMINAL NOUN PHRASE

  1. (Grammar) The data in (1) involves a comparison between the two DPs.

    1. a jewel of a village

    Indeed, Den Dikken (2006) designates it as a Comparative Qualitative Binominal Noun Phrase. In its copular variant, the village is equated with a jewel:

    1. a village is a jewel ⟶ village = jewel

     | Angelapia Massaro, 2019
  2. (Grammar) The Spanish comparative qualitative binominal noun phrase (c-QBNP) (Español-Echevarría 1997, 1998, García and Méndez 2002, Casillas 2003, den Dikken 2006, Bartra and Villalba 2006, Villalba and Bartra-Kaufmann 2010, González-Rivera and Delicado-Cantero 2010) displays the following syntactic structure:
    DEF-N/A
    'Def-N/A
    de
    of
    DEF-N
    Def-N'
    and, like the attributive QBNP, involves DP-internal predication. However, its meaning is different from attributive QBNPs. Consider, for instance, (1a). In this example the AP-predicate applies directly to the DP-subject.

    1. a.
       
      el
      the
      idiota
      idiot
      del
      of-the
      decano
      dean
        'the idiot of the dean'
      b.
       
      el
      the
      decano
      dean
      es
      is
      un
      an
      idiota
      idiot
        'The dean is an idiot.'

     In English, there is an attributive QBNP variant that has the two NPs juxtaposed without the intervention of any lexical material between them (2a,b); this is not possible, however, in English comparative QBNPs—i.e., (3a) cannot be paraphrased as (3b) (den Dikken 2006):

    1. a. an idiot of a doctor
      b. an idiot doctor
    2. a. a jewel of a village
      b. * a jewel village

COMPATIBILITY

  1. (Semantics) In this study, semantic compatibility between two or more linguistic components is defined as the following: The prototypical semantic specifications of the two linguistic components must be conceptually consistent (Yoon 2012). For the prototypical semantic specification in this definition, I adopt the prototype model (Rosch 1977) in which a category is defined with reference of a prototype, i.e. a schematized representation of typical instances (Langacker 1988). Therefore, when I discuss the semantic compatibility between a construction and various verbs, I compare the prototypical semantics of the construction and the verbs when they are abstracted from specific instances. | Soyeon Yoon, 2013
  2. (Syntax) Commonly understood as the ability of a word to be combined in a sentence with certain elements, both subordinate (kernel connection) and non-subordinate to it, and where it itself acts as a subordinate element (adjunct connection). | O. Yu. Zaitseva, O. V. Gvozd, and Yu. L. Dobrovolska, 2023
  3. (Syntax) Compatibility is the main feature of language units based on syntagmatic relations. Syntagmatic relations is the capacity of language units to link to one another in a speech sequence as a part of the text, sentence, words in accordance with the laws of language. Compatibility is a linguistic category spread in every area of language. The rule that holds "combinability is the combination of words with words, sentence with sentence" is stereotypical and recognized only at the grammatical level. Sounds in the language have the capability to be combined or not to be combined with each other. Affixes are attached to the root differentially under the laws of language. Words are also combined with each other depending on the content plane and the expression plane. To the extent that this is true, the compatibility phenomenon is the category that plays a significant role in determining phonetic, lexical, morphological, syntactic laws of the language. | Amirbekova Aigul Baydebekkyzy, Khabiyeva Almagul, Soltanbekova Alfia, and Taubaldiyev Meirambek, 2019
  4. (Lexicology) According to Kotyolova (1975), the lexical compatibility is the ability of a word (as a lexeme) to collocate with other words (also as lexemes) and the total sum of its lexical valencies. Other authors define it as the ability of a word to collocate syntactically with words from a limited list, i.e. the ability to generally combine with a limited number of words, irrespective of its function in speech. | Margareta Morarescu, 2007
  5. (Dialectology) A synchronic dialectological concept that operates on the lexical level. It assesses the degree of lexical relationship that exists between two or more varieties of a given language at a given time irrespective of geography; that is, it "analyzes the 'synchronic consequences' of ... partial differences within a framework of partial similarity."
     Compatibility differs from synonymity in that its domain of operation is much wider, for it comprehends lexical items of a given variety and their equivalents in one or more other varieties. Synonymity, on the other hand, is restricted to lexical items and their equivalents in one and the same variety. For example, the English gloss 'lemons' has in the Tripoli variety of Arabic two words: /mrạ́ːkbe/ and /hạ́ːmụD/. These items are considered synonymous in Tripoli Arabic (Tp). The Sidonese variety of Arabic (Sd), however, has the equivalent /laymuːn/. These equivalent lexical items, namely, Tp /mrạ́ːkbe/, /hạ́ːmụD/ and Sd /laymuːn/, are assessed as compatible with each other since they mean 'lemons' in the varieties in which they occur. Such a group of two or more equivalent items is called a set of compatible items.
     Compatibility depends completely on meaning for the isolation of sets of compatible items, for lexical items are compatible if they have the same meaning. However, sets of compatible items can be subclassed according to formal criteria (i.e., whether they are the same in form or not). Thus, two or more items that are the same in meaning but different in form, such as Tp /hạ́ːmụD/ and Sd /laymuːn/ 'lemons', are contrastive; items that agree in both meaning and form, such as Tyrean Arabic (Ty) /zunnạ́ːr/ and Beiruti (Ashrafiyyah) (Ba) /zinnạ́ːr/ 'belt', are noncontrastive.
     A noncontrastive set of compatible items comprises cognates that may be isolated by the application of the comparative method. However, a contrastive set of compatible items includes noncognates and asymmetrical cognates.
     Compatibility operates on a synchronic level. | Frederic J. Cadora, 1966
  6. (Examples)
     ○ A more detailed examination of Slavic phonological systems confirms that the preservation of the Hebrew name דָּוִד 'David' cannot be adequately explained by phonotactic compatibility alone. While it is true that the consonantal structure d-v-d does not violate Slavic phonological constraints, this fact is insufficient as an explanatory principle. Numerous loanwords that are equally compatible with Slavic phonotactics nevertheless undergo systematic adaptation, including vowel modification, consonantal substitution, or prosodic restructuring. | Željko Stanojević, 2026
     ○ Studies of internet graphic communication argue that Latin letters co-exist with abbreviations, mixed-code strings and visually motivated signs that compensate for tone and gesture in fast interaction (Komilov 2020). At the same time, phonetic compatibility and perception guide which borrowed forms stabilize: cross-linguistic phonetic differences can yield spelling variation until communities converge on the most recognizable and typable solutions (Islomov 2025). | Komilov Javokhir, 2026
     ○ Vietnamese (Austro-Asiatic; Vietnam) is a wh-in-situ language. All the wh-expressions (except for the subject 'who' and 'why') are restricted to the clause-internal position and are banned from being clause-internal. The 'when' questions behave differently. The 'when'-expression is compatible with both the clause-internal and clause-external positions.
     T heads have temporal features that need to be checked. The 'when'-expression is base-generated in a non-temporal projection. It then moves up to check the feature of the T head. Feature compatibility is required for checking. | Thủy-Thương (Beryl) Bùi, 2026
     ○ Adaptations like English Gertrude becoming Klingon (constructed) ghertlhuD demonstrate phonological transformation, where Klingon's alveolar lateral affricates replace English consonant clusters to align with Klingon phonotactics. Similarly, vowel epenthesis and consonant substitutions ensure Klingon phonological compatibility, balancing "alien-ness" with reader accessibility. | Chiara Meluzzi, 2025
     ○ Lexical misuse or semantic error is the incorrect use of words in speech or writing, generally related to meaning, connotation, collocation or grammatical compatibility. Lexical misuse includes semantic error, that is the use of a word whose meaning opposes the speaker's intention. | Laura-Ionela Ionică, 2025
     ○ This paradigm was a morphological compatibility decision task with a total of two paragraphs. Each paragraph consisted of seven sentences suitable for Turkish written linguistic structure; five sentences in each paragraph had a blank space inside. At the top of each paragraph, target words derived from the same root with proper suffixes (e.g., göz, gözlük, gözlüğüm etc.) fitting the blanks in that paragraph were presented in mixed order. | Tevhide Kargin, Birkan Guldenoglu, Hilal Gengec, Merih Toker, 2023
     ○ An effective solution to the task of identifying idiomatic expressions calls for the ability to relate the meaning of its component words with each other (e.g., Baldwin 2005, McCarthy et al. 2007) as well as with the context (Liu and Hwa 2019). This aligns with the widely upheld psycholinguistic findings on human processing of a phrase's figurative meaning in comparison with its literal interpretation (Bobrow and Bell 1973). Toward this end, we rely on the contextualized representation of a potential idiomatic expression (PIE, accounting both for its internal and contextual properties), hypothesizing that a figurative expression's contextualized representation should be different from that of its literal counterpart. We refer to this as its semantic compatibility (SC)—if a PIE is semantically compatible with its context, then it is literal; if not, it is figurative. The idea of SC also captures the distinction between literal word combinations and idioms, in terms of the semantics encoded by both (Jaeger 1999) and the related property of selectional preference (Wilks 1975)—the tendency for a word to semantically select or constrain which other words may appear in its association (Katz and Fodor 1963). | Ziheng Zeng and Suma Bhat, 2021
     ○ The structure of the field is formed by peripheral zones, and the one closest to the center is generated by a direct semantic connection with the semantic core. All subsequent zones are based on the connections with the previous layers. Mikhalyov (1995) applied the six-step rule formulated by Karaulov (1981), according to which, the connection between two randomly chosen words can be established through no more than five intermediate words, corresponding to the six steps. Applying this rule to a phonosemantic field, Mikhalyov (1995) showed the stability and strength of internal semantic connections. Thus, in analyzing semantic compatibility, one should also study the connectivity between words that occur together in the texts, considering the distance from the sixth step to the center—the word with the highest frequency. | Vladimir Pavlovich Klochkov, Galina Raisovna Rybakova, Natalya Olegovna Vasileva, Tatiana Viktorovna Malkova, and Irina Vladimirovna Krotova, 2019
     ○ The article deals with the structural and functional-semantic features of the portmanteau words of English origin in Modern German. The borders of this linguistic blending depend on semantic relations between initial parts of the contamination and their phonetic compatibility. | Kudrikova and Dyakov, 2016
     ○ We conducted two experiments to examine the role of syntactic, lexical and contextual factors on the interpretation of idiomatic expressions. Experiment 1 examines the role of syntactic compatibility and lexical compatibility on the real-time processing of potentially idiomatic strings. Experiment 2 examines the role of contextual information on idiom processing and how context interacts with lexical information during processing. | Edward Holsinger, 2013
     ○ The software layer of SAMA 3.1 relies on a data layer that consists primarily of three Arabic-English lexicon files: prefixes (1,328 entries), suffixes (945 entries), and stems (79,318 entries representing 40,654 lemmas). The lexicons are supplemented by three morphological compatibility tables used for controlling prefix-stem combinations (2,497 entries), stem-suffix combinations (1,632 entries), and prefix-suffix combinations (1,180 entries). | Mohamed Maamouri, David Graff, Basma Bouziri, Sondos Krouna, Ann Bies, and Seth Kulick, 2010
     ○ Stress patterns of English and perceptual pattern of the six Vietnamese (Austroasiatic; Vietnam) tones were compared (Vietnamese assigns one tone to each syllable). The analysis of Vietnamese tones immediately preceding code-switching reveals that there is a statistically significant proportion of the high tone group at the point of switching. This fact, together with the perceptually phonological compatibility between Vietnamese tones of high and mid-level pitch and English stressed vs. unstressed syllables, suggests that code-switching tends to be facilitated by the mid-level to high pitch Vietnamese tones. | Tuc Ho-Dac, 1997

COMPETITION

  1. (Psycholinguistics) A psycholinguistic effect which arises in the task of selecting an intended unit from among a number of elements concurrently activated in the processing network. The audible and visible outcome of the selection process is language use. Language structure is the prerequisite for competition in that it provides the set of competitors. When competition is low, consistent (i.e., invariant) language use emerges. When competition is high, language use is variable, i.e., synchronic variation occurs. When competition changes over time, language change takes place. Thus, it is language processing in general and competition in particular that constrains and binds together many phenomena of language use, structure, variation, and change. | Thomas Berg, 2014
  2. (Morphosyntax) The symmetrical view of the morphology-syntax interface is presented by Ackema and Neeleman (2001, 2004). They assume that morphology and syntax are parallel generative systems and thus compete for structural realization; in this sense, there is no asymmetry between these modules. Based on this assumption, Ackema and Neeleman develop a theory that hypothesizes that an unmarked realization form of a structure is parameterized in terms of either morphology or syntax, depending on which is more prominent in a given language. | Kazuya Nishimaki, 2014
  3. (Examples)
     ○ A complete theory of scalar implicature involves two components. First, one needs to describe a system predicting which inferences are generated by the competition between a given sentence and a given set of alternatives. This has been the subject of much research (Horn 1972, Gazdar 1979, Gamut 1991, Chierchia et al. 2012). | Brian Buccola, Manuel Križ, and Emmanuel Chemla, 2021
     ○ Complementary distribution is a consequence of a general principle of evolutionary biology, competitive exclusion, which further provides a uniform account of both allomorphic variation and the rivalry between affixes in terms of competition for distributional resources. The distribution of inflectional competitors is a type of spatial partitioning, restricted by the morphosyntactic system of a language, while derivational rivals benefit from having to name externally driven concepts. The English suffixes -ce, -cy, and -ntial are analyzed in detail as examples of competition for distribution. | Mark Aronoff, 2019
     ○ During language processing, bilinguals may experience simultaneous activation of both languages, or parallel activation. Parallel activation of the two languages may increase overall cognitive load as competition from an irrelevant language is overcome (e.g., Blumenfeld and Marian 2013, Freeman, Shook, and Marian 2016, Kroll and Bialystok 2013, Kroll, Bobb, Misra, and Guo 2008, Linck, Hoshino, and Kroll 2008). For example, bilinguals access both within- and between-language competitor words during auditory comprehension and have to inhibit irrelevant words across languages (e.g., plug activates plum and plancha 'iron' for a Spanish-English bilingual; Blumenfeld and Marian 2013). In contrast, when monolinguals hear plug, they may activate multiple competing words within the same language only (e.g., phonological competitor plum, e.g., Blumenfeld and Marian 2011, Tanenhaus, Spivey-Knowlton, Eberhard, and Sedivy 1995). Therefore, bilinguals may rely on cognitive control during language processing to inhibit not only within-, but also between-language interference in order to select the target word (e.g., Blumenfeld and Marian 2011, 2013, Giezen, Blumenfeld, Shook, Marian, and Emmorey 2015, Mercier, Pivneva, and Titone 2014). | Max R. Freeman, Henrike K. Blumenfeld, and Viorica Marian, 2017
     ○ Smith and Wheeldon (2004) showed that in picture descriptions in which two nouns were required, participants took longer to plan their utterances when descriptions included conceptually similar nouns (e.g., saw and axe in planning the saw and the axe move together), compared to conceptually dissimilar nouns (saw and cat). They suggested that the temporal overlap in accessing the nouns gives rise to interference or competition between these words during phrase planning. | Silvia P. Gennaria, Jelena Mirkovia, and Maryellen C. MacDonald, 2012
     ○ We propose a new information theoretic method for competitive learning and apply it to a problem of linguistic rule acquisition. The new method can contribute to neural computing from three perspectives:

    1. It is a competitive learning method that can directly control competitive unit activation patterns.
    2. Competition is realized by maximizing information in competitive units.
    3. The method can provide a tool and guiding principles to simulate a process of language acquisition.

     | Ryotaro Kamimura, Taeko Kamimura, and Thomas R. Shultz, 2001

COMPETITION MODEL

  1. (Psycholinguistics) Portrays the idea that mental processing is competitive in the classical Darwinian sense. If we consider the biological world, we realize that each species is attached to a particular niche or habitat. In that niche, each member while cooperating in the competition against other species, competes with other members of its species. The abilities and tendencies of competing species, of predators, and of species that serve as food sources tightly control the habitat of them. The mental world also echoes the same tight, interlocking dependency, as MacWhinney (1986) suggests. As far as perception is concerned, many ideas are called to the mind, but few are chosen. The final perception of a situation is determined by those constructs which, together, most successfully matched the stimulus. The ideas can win out only if they are in harmony with the other ideas in that particular context.
     Cooperation causes a percept or an action to gain strength over the other actions with which it is interrelated. The better it matches other ideas, the more an idea can win out over its competitors. According to what MacWhinney (1986) believes, competition is forever connected with cooperation. The same phenomenon is detected in language processing: here the unit of competition is not the species or the individual, but the lexical item. The domain of each word is formed by the related meanings and sounds and by the range of responses of the lexical items with which it competes. During sentence processing, each lexical item sets up expectations for other lexical items.
     When processing is successful, these expectations interlock tightly. Yet, as in natural systems, there is always some variation in the system which can sometimes result in the occurrence of errors. | Farid Ghaemi and Mastaneh Haghani, 2011
  2. (Psycholinguistics) The main idea underlying the Competition Model is that mental processing involves a continual decision-making process in which there are many possible candidates competing for each categorization decision and the language user must be able to evaluate the candidacy of each alternative in terms of the cues that support it. In the Competition Model, the process of language learning is usually understood in terms of ways in which the learner comes to adapt his behavior to conform increasingly more closely to the actual way in which cues function in the environment. I will not provide a complete characterization of the Competition Model here, instead referring the reader to the papers on the subject in MacWhinney (1987) and MacWhinney and Bates (in press). | Brian MacWhinney, 1989

COMPLEMENT

  1. (Syntax) Phrases expanding notions inherent in the predicate are considered to be complements. (Gibson, 1973, p. 66) Phrases which are expansions of the inflectional person categories of the predicate are also complements. In Secwepmctsín, phrases and clauses which complete predicative notions occur as complements introduced by 'ʔes'.
     Complements can be differentiated according to the following properties:
    1. A subjective complement immediately precedes or follows the predicate.
    2. An objective complement follows the predicate, and occurs after the subject if it also follows the predicate.
     (Gibson 1973) | INLP Linguistic Glossary
  2. (Syntax) YP in [H' H YP], where H is a head and H' the projection of H. According to X-bar theory, the complement of a head X0 is defined either as a position attached or adjoined to X', or as a sister of X0. Thus, in configuration (1), either A and B are complements of X0, or just B (the sister of X0). 
    1.       X'
     / \
    /   \     
   A     X'
        / \
       /   \	
      B     X0
     Sometimes, the complement of a head X0 is equated with its internal argument(s). Chomsky 1981, 1986; Williams 1980) | Utrecht Lexicon of Linguistics, 2001
  3. (Grammar) In many modern grammars (for instance in those that build on the X-bar schema), the object argument of a verbal predicate is called a "complement". In fact, this use of the term is the one that currently dominates in linguistics. A main aspect of this understanding of complements is that the subject is usually not a complement of the predicate, e.g.:
    1. He wiped the counter.
      The NP the counter is the object complement of the verb wiped.
    2. She scoured the tub.
      The NP the tub is the object complement of the verb scoured.
     The NPs the counter and the tub are necessary to complete the meaning of the verbs wiped and scoured, respectively, hence they are complements. | Wikipedia, 2019

COMPLEMENT-DESCENDING GENERALIZATION

  1. (Syntax) 
    Complement-Descending Generalization
    In head-initial structures, c-selected and non-agreed phrases may only merge as complements or in descending structures.
     | Philip Shushurin, 2025
  2. (Syntax) In the Russian noun phrase, which is head-initial, (non-adjectival) dependents generally exhibit ascending orders, i.e. high arguments follow low arguments, as in (1), with one major exception: non-possessor / author genitives must be adjacent to the nominal head, as in (2), irrespective of the properties of other dependents.

     I will show that the pattern in (1-2) constitutes a genuine counterexample to Janke and Neeleman's (2010/2012) and Belk and Neeleman's (2017) Case Adjacency account, which suggests that Object Adjacency effects are driven by the case computation. I formulate a novel generalization, the Complement-Descending Generalization, according to which in head-initial structures, c-selected and non-agreed phrases may only merge as complements to the head or in descending structures. Such effects are notably absent in head-final structures.
     This account successfully explains traditional object adjacency effects and can be extended to encompass further phenomena, such as Adjectival Adjacency, as well as some other left-right asymmetries. | Philip Shushurin, 2026

COMPLEMENTARY DISTRIBUTION

  1. (General) Two elements a and b are in complementary distribution if a, but not b, occurs in those environments where on general grounds we may expect both a and b, while b, but not a occurs in the complementary set of environments. | Utrecht Lexicon of Linguistics, 2001
  2. (Phonology) Often taken as an indication that two superficially different elements are one and the same at a deeper level. Two sounds /a/ and /b/ are in complementary distribution when one of the two (/a/) occurs in all environments except those in which /b/ occurs and vice versa.
     Example: In English [p] and [ph] are in complementary distribution, since [ph] occurs syllable-initially when it is directly followed by a stressed vowel (cf. pin [phin]), whereas in all other positions [p] is found. In Hindi, however, [p] and [ph] can occur in the same position and are distinctive. | Utrecht Lexicon of Linguistics, 2001
  3. (General) Distinct from contrastive distribution and free variation. The relationship between two different elements of the same kind in which one element is found in one set of environments and the other element is found in a non-intersecting (complementary) set of environments.
     The term often indicates that two superficially different elements are the same linguistic unit at a deeper level, though more than two elements can be in complementary distribution with one another. | Wikipedia, 2023

COMPLEMENTIZER

  1. (Syntax) A conjunction which marks a complement clause. In English:
    1. I know that he is here.
    2. I refuted the supposition that he is here.
    3. I am doubtful that he is here.
     | SIL Glossary of Linguistic Terms, 2003
  2. (Syntax) A functional category (part of speech) that includes those words that can be used to turn a clause into the subject or object of a sentence. For example, the word that may be called a complementizer in English sentences like Mary believes that it is raining. The concept of complementizers is specific to certain modern grammatical theories; in traditional grammar, such words are normally considered conjunctions. The standard abbreviation for complementizer is C.
     The complementizer is often held to be the syntactic head of a full clause, which is therefore often represented by the abbreviation CP (for complementizer phrase). Evidence that the complementizer functions as the head of its clause includes that it is commonly the last element in a clause in head-final languages like Korean or Japanese, in which other heads follow their complements, whereas it appears at the start of a clause in head-initial languages such as English, where heads normally precede their complements (Sells 1995). | Wikipedia, 2022

COMPLETIVE ASPECT

  1. (Grammar) Refers to an aspectual form that expresses an action that has been carried out "thoroughly and to completion". The term perfective aspect is very similar in meaning, but it is distinguished from completive by several authors. (Bybee, Perkins, and Pagliuca 1994) | Glottopedia, 2008
  2. (Grammar) Indicates that an action is, has been, or will be definite and complete(d). It implies that the action was definitely accomplished. | H. Schiffman, 2005

COMPLETIVE PHRASAL VERB
(Grammar) E.g., to burn down, to wipe out, to use up, where the particle has a sense of "completion" and does not usually alter the basic meaning of its verb. | Brock Brady, 1991

COMPLEX LEXEME

  1. (Morphology) Although the differentiation of simple and complex lexemes is only the first step towards the analysis, it is evident already at this stage that the borderline is not very clear. Besides obvious instances of simple words, such as white, rare, catch and money, and obvious instances of complex words, such as unrecognizable, nippy, government-owned and milkman, there are also words such as conflict, prepare, impact, and odor which are placed somewhere in between because they are partly analyzable, especially for a native speaker of English with some knowledge of classical languages. Moreover, there are lexemes such as superficial, amenity, but also native Tuesday and beware, which are more likely to be classified as complex, although it is also problematic to fully describe their structure from the synchronic point of view. | Kateřina Vašků, 2019
  2. (Examples)
     ○ The comparative concept of binominal lexeme (Pepper 2022), a noun-noun compound or its functional equivalent, is a suitably restricted and more manageable 'daughter comparative concept' of the more general complex lexeme. The examples in (1) all mean 'railway':

     ○ The material on which the analysis is conducted is a particular class of complex lexemes in French, the so-called "neoclassical compounds", e.g., words ending in -crate, -cratie, -logue and -logie. | Marine Lasserre and Fabio Montermini, 2021
     ○ A compound is a complex lexeme that can be thought of as consisting of two or more base lexemes. | Laila Damayanti, 2020
     ○ In the case of complex lexemes, we have simultaneous parallel activations (Lamb 1999, 2005/2007, Müller 2000). For instance, the Chinese compound hong 'fragrant' plus kong 'harbor' is the name for the territory of Hong Kong. For Chinese speakers it is both (simultaneously and in parallel) a primary meaning, the name of a territory, and a "shadow meaning" (Chafe 2000): 'fragrant harbor'. | José María Gil, 2016
     ○ I take a new approach to certain multi-word strings in German such as:

    1. heftig in die Kritik geraten
      'to be heavily criticized'
    2. immer der Erste sein
      'to always be the first'
    3. richtig Geld verdienen
      'to make real money'
    4. richtig Gas geben
      'increase effort'

     Common to each of the multi-word strings is that we have a modifier, a noun or a PP, and a verb.
     The schema I propose is inspired by Function Composition as used in Categorial Grammar. Each of the three elements in the string is individually a syntactic atom of a multi-word string. The combination as a whole should be considered one complex lexeme, the building of which in syntax is licensed lexically. | Philippa Cook, 2013

COMPLEX PRONOUN

  1. (Morphology) For example, in Québec French there are simple pronouns nous 'us', vous 'you plural', elles 'they.F', and eux 'they.M'; and complex pronouns nous-autres 'us', vous-autres 'you', and eux-autres 'them'. | Mireille Tremblay, 2022

COMPLEX XP CONSTRAINT

  1. (Syntax) 
    The Complex XP Constraint (where X ≠ non-ergative V)
    Extraction out of complements of lexical heads is disallowed.
     | Željko Bošković, 2019
  2. (Syntax) Given "complex NP" being defined as "a noun modified by a clause":
    The Complex NP Constraint (CNPC)
    Extraction from complex NPs is disallowed.
     When properly generalized the CNPC represents a pervasive pattern found in a number of contexts. In particular, extraction is banned not only from clausal but all nominal complements. Furthermore, APs and PPs pattern with NPs. This means that with the exception of Vs, extraction is banned from complements of lexical heads. Hence,
    The Complex XP Constraint (where X ≠ V)
    Extraction out of complements of lexical heads is disallowed.

COMPLEXITY-BASED ORDERING

  1. (Morphology) The Complexity-Based Ordering Hypothesis (CBO) (Hay 2003) posits that cognitive processing restricts affix combinability above and beyond structural restrictions (e.g. inter-nation-al-iz-ation, but *internation-iz-ation-al, despite being interpretable and meeting structural restrictions). Specifically, CBO states that affixes that tend to be parsed during lexical access occur farther from the root (in English) than affixes that do not, because this facilitates lexical access. | Andrea Sims and Jeffrey Parker, 2012
  2. (Morphology) Jennifer Hay (2002) proposed a psycholinguistic approach to affix ordering now known as Complexity-Based Ordering (CBO), which claims that affix order is determined by the parsability of the affixes, i.e. more separable affixes can appear only outside of less separable affixes. Hay shows that this principle accounts for why many grammatical affix combinations are unattested. CBO has since been supported by research of derivational affixes (English prefixes, English suffixes and Russian suffixes). | Robert Reynolds, 2013
  3. (Morphology) A psycholinguistic model of morphological complexity, according to which an affix which can be easily parsed out in processing should not occur inside an affix which cannot. This model has been called "complexity based ordering". The general claim is that affixes can be approximately ordered along a hierarchy of complexity, with more separable affixes at one end, and less separable affixes at the other end. More separable affixes can attach outside less separable affixes, but not vice-versa. | Jennifer Hay and Ingo Flag, 2004
  4. (Morphology) CBO builds on the Parsability Hypothesis (Hay 2001, 2002, 2003). | Stela Manova, 2022

COMPLEXITY FILTER

  1. (Syntax) In Koopman and Szabolcsi (2000) we account for the different word order and constituency of verbal complexes in Hungarian, Dutch and German by a derivational theory which relies on overt (remnant) XP movement only. The derivations yield paradigms that are not always attested in full in a particular language: there are language specific gaps in the paradigms. Koopman and Szabolcsi argue that these gaps should be accounted for by a new brand of filters, complexity filters, which act on the representations that the derivations generate. Complexity filters are sensitive to overt material only, and impose restrictions on the "size" or "internal complexity" of certain constituents in designated Spec positions at the end of the derivation.
     Movement is not subject to economy conditions: the computational system is blind and fully automatic. Different surface patterns result from the particular history of the derivation: which parts of the structure may be split (expressed by language specific "splitting" parameters), and what "size" constituent is allowed to occupy a particular Spec position at the end of the derivation (expressed by language specific complexity filters). Splitting parameters and complexity filters are independent, but in many cases interact to restrict what size constituent can be pied-piped, and what parts of the structure muse be "chopped up" into smaller pieces. | Hilda Koopman, 2008
  2. (Semantics) Katzir (2007) and Fox and Katzir (2011) formalize a notion of complexity that requires formal alternatives to be no more complex than the asserted one. This formal complexity filter on Excl can be stated thusly:
    Complexity Filter on Excl
    Excl(φ) ⊆ {Basic(ψ): ψ is no more complex than φ}
     | Bernhard Schwarz and Michael Wagner, 2024
  3. (Example)
     ○ To see how arbitrary the Koopman and Szabolcsi (2000) provisions for Hungarian are, consider how the language would look if we simply changed one of them, and kept the others the same. For example, suppose the Hungarian complexity filter forced the movement of XPs smaller than InflP, rather than larger than InflP. The language that results from such an adjustment would have a bizarre collection of properties form the point of view of the accounts which make the X0 distinction. But isn't that a point in favor of such theories? | Edwin Williams, 2004
     ○ Fanselow and Ćavar (2001) argue that the German paradigm (1) shows the need for complexity restrictions independent of head status. Verbs pied-pipe their unstressed particles when they undergo V2 movement (1a,1c), while stressed particles are stranded (1b,1d). (1) indeed establishes the need for a morpho-phonological complexity filter for the second position. (1) also shows that lexical entries can be split up in a V2 construction. (1) does not show that elements other than an X0 category can occupy the second position, however. The paradigm in (1) constitutes no reason for abandoning the idea that X0 elements only undergo V2 movement in German.

* COMPLEXONSET

  1. (Optimality Theory) A markedness constraint:
    * COMPLEX ONSET
    Don't produce complex onsets (CCV-).
     | Paul Boersma and Clara Levelt, 2000
  2. (Examples)
     ○ In an underlying word-initial consonant cluster, *COMPLEXONSET is in conflict with the faithfulness constraints MAX-IO (Input segments must have counterparts in the output) and DEP-IO (The output must preserve all segments present in the input). | Somdev Kar, 2012
     ○ This paper focuses on four strategies of onset reduction employed by a single child (4;0-4;4) acquiring Polish: deletion, coalescence, metathesis, and gemination.
     The OT account makes it possible to envisage the four strategies as different surface responses to the undominated *COMPLEXOnset which militates against onset clusters. The choice of a particular strategy as well as its restriction to a particular word position is not random but follows from the interplay between * COMPLEXOnset, sonority-based syllable structure constraints (Margin Hierarchy, CONTACT LAW), context-sensitive markedness constraints (CODA CONDITION, *Nasal-Fricative) and faithfulness constraints. | Beata Łukaszewicz, 2007

* COMPLEXSEGMENT

  1. (Optimality Theory) A constraint:
    * COMPLEXSEGMENT:
    Assign one violation for every output segment with more than one articulator feature.
     | Larry Lyu, 2026
  2. (Optimality Theory) 


     | Kathleen M. O'Connor, 1999
  3. (Optimality Theory) A segmental markedness constraint:
    * COMPSEG: No complex segments.
     | Jaye Padgett, 1995
  4. (Example)
     ○ An assumed constraint like *ComplexSegment (e.g. in Padgett 1995) would presumably assign a violation to any segment with more than one place. Its violation profile is shown below, compared with m.KPT ("Don't be dorsal, labial, or coronal").
    m.KPT versus Hypothetical * ComplexSegment
      m.KPT *ComplexSegment
     T   1   0
     P   1   0
     K   1   0
     KP   2   1
     TP   2   1
     !   2   1
     Among these candidates, the two constraints are effectively identical; each only differentiates between complex stops and simple stops. However, m.KPT is independently motivated by the constraint building mechanism from the universal markedness scale. The *ComplexSegment constraint would have to be assumed separately. | Nick Danis, 2017

COMPONENTIAL ANALYSIS

  1. (Semantics) According to the theory of semantic components, semantic features have positive (marked) and negative (unmarked) values. If we take for example the words women and flower we do not seem to be able to relate their values because lexical semantics establishes the value (+female) to women and (−human) to flower. These two lexical units may have further values such as [(affection), (beauty), (care), (love), (protection)] to women and [(beauty), (love), (smell)] to flower. The recurrent values in both cases are (love) and (beauty). The two can be an exemplification to the lexical units women and flower instead of (+female) and (−human). In general, lexical units have a lexical creativity not seen in their independent form but retained from the paradigmatic interaction between their values.

    The meaning of each term can be analyzed by a set of meaning components or properties of a more general order, some of which will be common to various terms in the lexicon. There may also be specific restrictions, for instance the nature and structure of features, and the procedures by which they are selected. However, the term componential analysis is often used to refer not only to simple decomposition into semantic components, but to models with much more powerful theoretical assumptions. (Patrizia Violi 2001)
     | Khadija Belfarhi, 2013
  2. (Semantics) Or, lexical decomposition. In the broadest sense, any attempt to formalize and standardize procedures for the analysis of word meanings. Componential analysis often aspires to represent the cognitive or psychological reality of the speakers, and to shed light on correlations between language and culture.
     The idea that word meanings may be broken down into combinations of simpler components is an ancient one, supported by a range of facts. These include:


     The assumption of decomposability underlies the definitional side of traditional lexicography. | Cliff Goddard, 2009

     ○ That the methods of componential analysis as they have been developed for analyzing linguistic forms are applicable in principle for analyzing other types of cultural forms is a proposition toward whose demonstration I have for some time sought to orient my ethnographic researches. | Ward H. Goodenough, 1956

COMPOSITE PROBE

  1. (Syntax) In recent approaches to the A' / A-distinction and how it is related to features (rather than structural positions alone), the call for composite probes grew stronger. Composite probes, as van Urk (2015) labels them, are two probes located on a single head, forming a probe conglomerate—an assumption that has been made for TMA-features on T or Infl already for a while (e.g., the combination of tense and φ-features on a single head). | Magdalena Lohninger, Iva Kovač, and Susanne Wurmbrand, 2022
  2. (Syntax) Person and number are sometimes forced to probe in unison. Person and number can form a composite probe, and select a target together (Coon and Bale, 2014).
     If two features on the same head can form a composite probe, we might find a composite probe made up of φ-features and A'-features: [Wh, φ] (a composite A / Ā probe). | Coppe van Urk, 2015
  3. (Syntax) The phenomenon where two (or more) features present on the same head probe together in unison, searching for the closest goal bearing both of the features involved in the probe, and ignoring goals with only one or the other of the features (Chomsky 2001, Bruening 2001, Pesetsky and Torrego 2001, Haegeman 2012, Rezac 2013, Coon and Bale 2014, Kotek 2014, Deal 2014). | Nicholas Longenbaugh, 2017

COMPOSITIONAL SEMANTICS

  1. (Semantics) Usually defined as a functional dependence of the meaning of an expression on the meanings of its parts. | Wlodek Zadrozny, 1995
  2. (Semantics) The building up of phrasal or sentence meaning from the meaning of smaller units by means of semantic rules. To account for speakers' knowledge of the truth, reference, entailment, and ambiguity of sentences, as well as for our ability to determine the meaning of a limitless number of expressions, we must suppose that the grammar contains semantic rules that combine the meanings of words into meaningful phrases and sentences. In other words, semantic rules are principles for determining the meaning of larger units like sentences from the meaning of smaller units like noun phrases and verb phrases.
     Our semantic rules must be sensitive not only to the meaning of individual words but to the structure in which they occur. Two rules:
    1. The meaning of [ S NP VP ] is the following truth condition:
      If the meaning of NP (an individual) is a member of the meaning of VP (a set of individuals), then S is true. Otherwise it is false.
    2. The meaning of [ VP V NP ] is the set of individuals X such that X is the first member of any pair in the meaning of V whose second member is the meaning of NP.
     These two semantic rules handle an essentially infinite number of intransitive and transitive sentences, and they account for our knowledge of the truth value of sentences by taking the meanings of words and combining them according to the syntactic structure of the sentence. | Hatice Eroğlu, 2012

COMPOSITIONALITY
(Semantics) A symbolic system is compositional if the meaning of every complex expression E in that system depends on, and depends only on

  1. E's syntactic structure, and
  2. The meanings of E's simple parts.
 If a language is compositional, then the meaning of a sentence S in that language cannot depend directly on the context that sentence is used in or the intentions of the speaker who uses it. So, for example, in compositional languages, the meanings of sentences don't directly depend on:  In compositional languages, the meaning of a sentence S directly depends only on the meanings of the words composing S, and the way those words are syntactically related to one another.
 Of course, simple expressions in a compositional language might have meanings that depend on the context or on the intentions of their users, as the referent of the English pronoun she can depend on who the speaker intends to be referring to. As such, sentences containing expressions such as she will indirectly depend on the intentions of their speakers, because the meaning of the sentence depends on the meanings of its simple parts and the meanings of some of those parts depend on the speaker's intentions.
 Several arguments purport to show that not only is natural language compositional, but that it must be, since we could not have the linguistic abilities we in fact do have, unless the languages we speak are compositional. | Michael Johnson, ?

COMPOUND

  1. (Morphology) Most Chinese words are compound words, composed of two or more constituent morphemes.
     Morphemes used as constituents in compounds are usually words by themselves, although there are also bound morphemes in the language. | Xiaolin Zhou, William Marslen-Wilson, Marcus Taft, and Hua Shu, 1999
  2. (Morphology) Compounding consists of the combination of two or more lexemes, whereas derivation is characterized by the addition of an affix, that is, a bound morpheme, to a lexeme.
     Compounding is accounted for by a set of Word Structure Rules which form part of syntax and combine lexical stems into compounds.
     Compounds have an internal structure that is accessible to other rules of grammar. For instance, there are rules for introducing linking elements into German compounds that must have access to the internal structure of such complex words (Anderson 1992).
     There is no sharp boundary between compounding and affixal derivation, since there are many borderline cases. | Geert Booij, 2005
  3. (Morphology)  Compounding, prima facie, presents a seemingly paradigm case of morphology-as-syntax. It is productive, and it manipulates items which are canonically themselves free morphemes and clearly independent terminal nodes. As shown by Lieber 1992, nominal compounding in English and other Germanic languages can even include syntactically complex phrases, as in the following four examples from Tucson Weekly film reviews by James DiGiovanna:
    1. a. These aren't your standard stuff-blowing-up effects. (06/03/2004)
      b. When he's not in that mode, though, he does an excellent job with the bikini-girls-in-trouble genre. (11/30/2006)
      c. I've always found it odd that the people who complain most about realism are comic-book and science-fiction fans. (12/23/2004)
      d. There's the aforementioned bestiality and drooling-stroke-victim jokes. (03/29/2001)

COMPOUND ANALYSIS

  1. (Morphology) Noun–noun compound analysis in natural language processing (NLP) is a compound problem consisting of several tasks that collectively deal with the syntax and semantics of this linguistic construction. Past work on compound analysis has typically focused—to varying degrees—on five tasks, namely:

    1. Compound identification: Identify compounds in written text or speech.
    2. Compound bracketing: Analyze the internal syntactic structure of compounds. For example, snake oil product is analyzed as a left-branching compound, i.e. [[snake oil] product].
    3. Compound compositionality prediction: Determine the degree of compositionality through relating the meaning of the compound as a whole to the meaning of its constituents. For example, the predominant contemporary use of snake oil product is non-compositional because its meaning cannot be immediately derived from the individual meanings of its constituents.
    4. Compound sense disambituation: Disambiguate the meaning of polysemous constituents in compounds. For example, the constituent product in dot product refers to the mathematical concept of multiplication, but in consumer product it refers to an article or substance for sale.
    5. Compound interpretation: Determine the thematic relations holding between the constituent parts of compounds. In layman's terms, this task amounts to determining that meat product is a food product that contains meat whereas hair product does not contain hair but is used for hair care.
     | Murhaf Fares, 2019
  2. (Example)
     ○ In analyzing the data collected for this paper, the scope for compound analysis was restricted, focusing only on compound nouns as one category of compound words. Firstly, the compound nominals were identified and selected from the news article Then followed their organization in a separate table, analysis and classification according to the theory on compound words and compound nouns. The selected words were further discussed in terms of their internal structure with an examination of specific cases.

COMPOUND DIPHTHONG

  1. (Examples)
     ○ We (Hangul: ㅞ; Korean name: 웨) is a compound vowel in Hangul, the alphabetic writing system for the Korean language, pronounced as /we/ in modern Standard Korean, akin to the initial sound in the English word wet (90-Day Korean 2026). It is constructed by combining the basic horizontal vowel ㅜ (u) with the vertical vowel ㅔ (e), forming a diphthong that glides from a 'w' sound to 'e' (How to Study Korean ?). ㅞ is a compound diphthong vowel in Hangul, developed shortly after its creation by King Sejong the Great in 1443–1446, combining ㅜ (u) and ㅔ (e). | Grokipedia, 2026
     ○ Analysis of the implosion of onomatopoeic refrains in the Lithuanian Folk Songbook has shown that the structure of the syllabic ending group can vary. The implosion of onomatopoeic refrains is dominated by open syllables, which count 92.1 per cent across the material studied. As often as not, syllables end in a vowel (79.5 per cent); endings consisting of a compound diphthong occur much less frequently (9.3 per cent). Closed syllables only total 7.9 per cent. | Jurga Trimonytė Bikelienė, 2013
     ○ There exist two types of diphthongs in Lithuanian language (Indo-European > Baltic; Lithuania) that are made of two vowels: compound diphthongs (ai, au, ei, ui, eu, oi, ou) and complex diphthongs (ie, uo). | Gražina Pyž, Virginija Šimonytė, Vytautas Slivinskas, 2011

COMPOUND PAST
(Grammar) A term used for the Spanish verb tense Preterito Perfecto Compuesto. The English equivalent is normally the Present Perfect, but I prefer the term Compound Past when dealing with this Spanish verb tense. There are two reasons for this:

  1. It maintains a certain logic with another verb tense that is of interest here, namely the Simple Past.
  2. Since it has been argued that time of speech is less crucial for the choice of the compound or the simple past form in several dialects (see De Mello 1994, Rodríguez Louro 2009), there is no reason to keep "Present" in the term used.

COMPOUND TENSE

  1. (Grammar) A structure formed with at least two verbs: the auxiliary and the main verb.
     The participle constitutes the main verb in compound tenses. In contrast to auxiliaries, participles form an open class of lexical items to which new members may be added, and are as rich in their semantic content as other lexical verbs. However, their categorial status is far from clear.
     I will assume that in Slavic, compound tense constructions are uniformly monoclausal, with the participle projecting the lexical head Part, which is dominated by several functional projections up to TP. The perfect auxiliaries in Slavic are often clitics, and their phonological requirements are reflected in the syntactic patterns of compound tenses. | Krzysztof Marek Migdalski, 1975
  2. (Grammar) In English, the compound tenses are a combination of present or past tense (shown through an auxiliary verb) with continuous or perfect aspect.


     The modal auxiliaries can be used in compound tenses:

    (Examples)
     ○ In Xhosa (Niger-Congo; South Africa), the BE gram has never been defined as a serial verb construction, but rather as a compound tense built around an auxiliary (the verb ba 'be') and another lexical verb (McLaren and Welsh 1955, Louw and Jubase 1963, Riordan, Mathiso and Davey 1969, Du Plessis 1978, Du Plessis and Malinga 1978, Visser 2005, 2015, Oosthuysen 2016). An analogous analysis may be found in research dedicated to the Zulu (Niger-Congo; South Africa) language (Van Eeden 1956, Doke 1981, Posthumus 1982, 1983, 1990, 2006, 2008, Taljaard and Bosch 1988, Poulos and Msimang 1998, Hall 2005, Groenewald 2014), as well as Swati (Niger-Congo; Eswatini; Taljaard, Khumalo, and Bosch 1991) and Ndebele (Niger-Congo, South Africa; Pelling and Pelling 1974, Ziervogel 1959). The understanding of the Nguni (Niger-Congo; Cameroon) BE gram in terms of a periphrasis composed of an auxiliary and a lexical verb also appears in comparative studies devoted to the (Southern) Bantu family (Gowlet 2003, Nurse 2008). | Alexander Andrason, 2018
     ○ Classification of compound tense forms in Egyptian Arabic:
    T. Mitchell (1962) C. Holes (1995/2004)
    kān fa‘al He had done kān fa‘al He had done
    yikūn fa‘al He will have done bi-ykūn fa‘al He will have done
    kān bi-yif‘al He used to do / was doing kān bi-yif‘al He was doing
    kān ḥa-yif‘al He was going to do kān ḥa-yif‘al He was going to do
    yikūn bi-yif‘al He will be doing ḥa-ykūn bi-yif‘al He will be doing
        ḥa-ykūn fa‘al He will have done
