{{Linguistics|Grammar}}

'''Generative grammar''' is a research tradition in [[linguistics]] that aims to explain the [[cognition|cognitive]] basis of language by formulating and testing explicit models of humans' subconscious grammatical knowledge. Generative linguists, or '''generativists''' ({{IPAc-en|ˈ|dʒ|ɛ|n|ər|ə|t|ɪ|v|ɪ|s|t|s}}),<ref>{{cite Dictionary.com|Generativist|date=August 2024}}</ref> tend to share certain working assumptions such as the [[linguistic competence|competence]]&ndash;[[linguistic performance|performance]] distinction and the notion that some [[domain-specific]] aspects of grammar are partly innate in humans. These assumptions are rejected in non-generative approaches such as [[usage-based models of language]]. Generative linguistics includes work in core areas such as [[syntax]], [[semantics]], [[phonology]], [[psycholinguistics]], and [[language acquisition]], with additional extensions to topics including [[biolinguistics]] and [[music cognition]].

Generative grammar began in the late 1950s with the work of [[Noam Chomsky]], having roots in earlier approaches such as [[structural linguistics]]. The earliest version of Chomsky's model was called [[Transformational grammar]], with subsequent iterations known as [[Government and binding theory]] and the [[Minimalist program]]. Other present-day generative models include [[Optimality theory]], [[Categorial grammar]], and [[Tree-adjoining grammar]].

== Principles ==

Generative grammar is an umbrella term for a variety of approaches to linguistics. What unites these approaches is the goal of uncovering the cognitive basis of language by formulating and testing explicit models of humans' subconscious grammatical knowledge.<ref name ="WasowHandbookUmbrella">{{cite encyclopedia |title=Generative Grammar |encyclopedia=The Handbook of Linguistics|year=2003|last=Wasow|first=Thomas|author-link=Tom Wasow|editor-last1=Aronoff|editor-first1=Mark|editor-last2=Ress-Miller|editor-first2=Janie|publisher= Blackwell|url=https://www.blackwellpublishing.com/content/BPL_Images/Content_store/WWW_Content/9780631204978/12.pdf|doi=10.1002/9780470756409.ch12}|pages=296,311|quote="...generative grammar is not so much a theory as a family or theories, or a school of thought...

=== Cognitive science ===

Generative grammar studies language as part of [[cognitive science]]. Thus, research in the generative tradition involves formulating and testing hypotheses about the mental processes that allow humans to use language.<ref>{{Cite book|last=Carnie|first=Andrew|author-link=Andrew Carnie|title=Syntax: A Generative Introduction |publisher=Wiley-Blackwell|year=2002|isbn=978-0-631-22543-0|pages=4-6,8}}</ref><ref name ="WasowHandbookMental">{{cite encyclopedia|title=Generative Grammar|encyclopedia=The Handbook of Linguistics|year=2003|last=Wasow|first=Thomas|author-link=Tom Wasow|editor-last1=Aronoff|editor-first1=Mark|editor-last2=Ress-Miller|editor-first2=Janie|publisher= Blackwell|url=https://www.blackwellpublishing.com/content/BPL_Images/Content_store/WWW_Content/9780631204978/12.pdf|doi=10.1002/9780470756409.ch12|pages=295-296,299-300}}</ref><ref name = "AdgerCogSci">{{cite book |last=Adger|first=David|author-link=David Adger|year=2003|title=Core syntax: A minimalist approach|publisher=Oxford University Press|page=14|isbn=978-0199243709}}</ref>

Like other approaches in linguistics, generative grammar engages in [[linguistic description]] rather than [[linguistic prescriptivism|linguistic prescription]].<ref>{{Cite book|last=Carnie|first=Andrew|author-link=Andrew Carnie|title=Syntax: A Generative Introduction|publisher=Wiley-Blackwell|year=2002|isbn=978-0-631-22543-0|page=8}}</ref><ref name ="WasowHandbookPreDes">{{cite encyclopedia|title=Generative Grammar|encyclopedia=The Handbook of Linguistics|year=2003|last=Wasow|first=Thomas|author-link=Tom Wasow|editor-last1=Aronoff|editor-first1=Mark|editor-last2=Ress-Miller|editor-first2=Janie|publisher= Blackwell|url=https://www.blackwellpublishing.com/content/BPL_Images/Content_store/WWW_Content/9780631204978/12.pdf|doi=10.1002/9780470756409.ch12|pages=295,297}}</ref>

=== Explicitness and generality ===

Generative grammar proposes models of language consisting of explicit rule systems, which make testable [[falsifiability|falsifiable]] predictions. This is different from [[traditional grammar]] where grammatical patterns are often described more loosely.<ref name ="WasowHandbookExpGen">{{cite encyclopedia|title=Generative Grammar|encyclopedia=The Handbook of Linguistics|year=2003|last=Wasow|first=Thomas|author-link=Tom Wasow|editor-last1=Aronoff|editor-first1=Mark|editor-last2=Ress-Miller|editor-first2=Janie|publisher= Blackwell|url=https://www.blackwellpublishing.com/content/BPL_Images/Content_store/WWW_Content/9780631204978/12.pdf|doi=10.1002/9780470756409.ch12|pages=298-300}}</ref><ref name = "AdgerExpGen">{{cite book|last=Adger|first=David|author-link=David Adger|year=2003|title=Core syntax: A minimalist approach|publisher=Oxford University Press|pages=14-15|isbn=978-0199243709}}</ref> These models are intended to be parsimonious, capturing generalizations in the data with as few rules as possible. For example, because English [[imperative mood|imperative]] [[tag questions]] obey the same restrictions that second person [[future tense|future]] [[declarative mood|declarative]] tags do, [[Paul Postal]] proposed that the two constructions are derived from the same underlying structure. By adopting this hypothesis, he was able to capture the restrictions on tags with a single rule. This kind of reasoning is commonplace in generative research.<ref name ="WasowHandbookExpGen"/>

Particular theories within generative grammar have been expressed using a variety of [[formal system]]s, many of which are modifications or extensions of [[context free grammars]].<ref name ="WasowHandbookExpGen"/>

=== Competence versus performance ===

Generative grammar generally distinguishes [[linguistic competence]] and [[linguistic performance]].<ref name ="WasowHandbookCompPerf">{{cite encyclopedia|title=Generative Grammar|encyclopedia=The Handbook of Linguistics|year=2003|last=Wasow|first=Thomas|author-link=Tom Wasow|editor-last1=Aronoff|editor-first1=Mark|editor-last2=Ress-Miller|editor-first2=Janie|publisher= Blackwell|url=https://www.blackwellpublishing.com/content/BPL_Images/Content_store/WWW_Content/9780631204978/12.pdf|doi=10.1002/9780470756409.ch12}|pages=297-298}}</ref> Competence is the collection of subconscious rules that one knows when one knows a language; performance is the system which puts these rules to use.<ref name ="WasowHandbookCompPerf"/><ref>{{cite book|last=Pritchett|first=Bradley|year=1992|title=Grammatical competence and parsing performance|publisher=University of Chicago Press|page=2|isbn=0-226-68442-3}}</ref> This distinction is related to the broader notion of [[David Marr (neuroscientist)#Levels_of_analysis|Marr's levels]] used in other cognitive sciences, with competence corresponding to Marr's computational level.<ref>{{cite book |last=Marr|first=David|author-link=David Marr  (neuroscientist)|year=1982|title=Vision|publisher=MIT Press|isbn=978-0262514620|page=28}}</ref>

For example, generative theories generally provide competence-based explanations for why [[English language|English]] speakers would judge the sentence in (1)<!--This refers to "*That cats is eating the mouse". Please update labels if necessary.--> as [[acceptability (linguistics)|odd]]. In these explanations, the sentence would be [[ungrammatical]] because the rules of English only generate sentences where [[demonstrative]]s [[Agreement (linguistics)|agree]] with the [[grammatical number]] of their associated [[noun]].<ref name = "AdgerCompPerf">{{cite book |last=Adger|first=David|author-link=David Adger|year=2003|title=Core syntax: A minimalist approach|publisher=Oxford University Press|pages=4-7,17|isbn=978-0199243709}}</ref>

:(1) *That cats is eating the mouse.

By contrast, generative theories generally provide performance-based explanations for the oddness of [[center embedding]] sentences like one in (2).<!--This refers to "The cat that the dog that the man fed chased meowed." Please update labels if necessary.--> According to such explanations, the grammar of English could in principle generate such sentences, but doing so in practice is so taxing on [[working memory]] that the sentence ends up being [[parsing|unparsable]].<ref name = "AdgerCompPerf" /><ref name="DillonMomaSlides">{{citation |url=https://shotam.github.io/LING611_slides/LING611_day1.pdf|last1=Dillon|first1=Brian|last2=Momma|first2=Shota|title=Psychological background to linguistic theories|year=2021|type=Course notes}}</ref>

:(2) *The cat that the dog that the man fed chased meowed.

In general, performance-based explanations deliver a simpler theory of grammar at the cost of additional assumptions about memory and parsing. As a result, the choice between a competence-based explanation and a performance-based explanation for a given phenomenon is not always obvious and can require investigating whether the additional assumptions are supported by independent evidence.<ref name="DillonMomaSlides"/><ref>{{cite encyclopedia|title=Deriving competing predictions from grammatical approaches and reductionist approaches to island effects|encyclopedia=Experimental syntax and island effects|year=2013|last1=Sprouse|first1=Jon|last2=Wagers|first2=Matt|last3=Phillips|first3=Colin|author-link3=Colin Phillips|editor-last1=Sprouse|editor-first1=Jon|editor-last2=Hornstein|editor-first2=Norbert|editor-link2=Norbert Hornstein|publisher=Cambridge University Press|doi=10.1017/CBO9781139035309.002}}</ref> For example, while many generative models of syntax explain [[syntactic island|island effects]] by positing constraints within the grammar, it has also been argued that some or all of these constraints are in fact the result of limitations on performance.<ref>{{cite encyclopedia|title=On the nature of island constraints I: Language processing and reductionist accounts|encyclopedia=Experimental syntax and island effects|year=2013|last=Phillips|first=Colin|editor-last1=Sprouse|editor-first1=Jon|editor-last2=Hornstein|editor-first2=Norbert|publisher=Cambridge University Press|url=http://www.colinphillips.net/wp-content/uploads/2014/08/phillips2013_islands1.pdf|doi=10.1017/CBO9781139035309.005}}</ref><ref>{{cite encyclopedia|title=Islands in the grammar?

Non-generative approaches often do not posit any distinction between competence and performance. For instance, [[usage-based models of language]] assume that grammatical patterns arise as the result of usage.<ref> {{cite book|last1=Vyvyan|first1=Evans|author-link=Vyvyan Evans|last2=Green|first2=Melanie|year=2006|title=Cognitive Linguistics: An Introduction|publisher=Edinburgh University Press|pages=108-111|isbn=0-7486-1832-5}}</ref>

=== Innateness and universality ===

A major goal of generative research is to figure out which aspects of linguistic competence are innate and which are not. Within generative grammar, it is generally accepted that at least some [[domain-specific]] aspects are innate, and the term "universal grammar" is often used as a placeholder for whichever those turn out to be.<ref name ="WasowHandbookUniversality">{{cite encyclopedia |title=Generative Grammar |encyclopedia=The Handbook of Linguistics|year=2003|last=Wasow|first=Thomas|author-link=Tom Wasow|editor-last1=Aronoff|editor-first1=Mark|editor-last2=Ress-Miller|editor-first2=Janie|publisher= Blackwell|url=https://www.blackwellpublishing.com/content/BPL_Images/Content_store/WWW_Content/9780631204978/12.pdf|doi=10.1002/9780470756409.ch12}|page=299}}</ref><ref name = "PesetskyUG">{{cite encyclopedia|title=Linguistic universals and universal grammar|encyclopedia=The MIT encyclopedia of the cognitive sciences|year=1999|last=Pesetsky|first=David|author-link=David Pesetsky|editor-last1=Wilson|editor-first1=Robert|editor-last2=Keil|editor-first2=Frank|publisher=MIT Press|doi=10.7551/mitpress/4660.001.0001 |pages=476-478}}</ref>

The idea that at least some aspects are innate is motivated by [[poverty of the stimulus]] arguments.<ref name = "AdgerPOS">{{cite book|last=Adger|first=David|author-link=David Adger|year=2003|title=Core syntax: A minimalist approach|publisher=Oxford University Press|pages=8-11|isbn=978-0199243709}}</ref><ref name ="Lasnik&LidzPOS">{{cite encyclopedia |title=The Argument from the Poverty of the Stimulus|last1=Lasnik|first1=Howard|author-link1=Howard Lasnik|last2=Lidz|first2=Jeffrey|author-link2=Jeffrey Lidz|encyclopedia=The Oxford Handbook of Universal Grammar|year=2017|editor-last=Roberts|editor-first=Ian|editor-link=Ian Roberts (linguist)|publisher=Oxford University Press|url=https://jefflidz.com/Docs/LasnikLidz2016.pdf}}</ref> For example, one famous poverty of the stimulus argument concerns the acquisition of [[yes-no question]]s in English. This argument starts from the observation that children only make mistakes compatible with rules targeting [[hierarchical structure (linguistics)|hierarchical structure]] even though the examples which they encounter could have been generated by a simpler rule that targets linear order. In other words, children seem to ignore the possibility that the question rule is as simple as "switch the order of the first two words" and immediately jump to alternatives that rearrange [[constituent (linguistics)|constituents]] in [[Tree (data_structure)|tree structure]]s. This is taken as evidence that children are born knowing that grammatical rules involve hierarchical structure, even though they have to figure out what those rules are.<ref name = "AdgerPOS"/><ref name ="Lasnik&LidzPOS"/><ref>{{cite journal|last1=Crain|first1=Stephen|author-link1=Stephen Crain|last2=Nakayama|first2=Mineharu|year=1987|title=Structure dependence in grammar formation|journal=Language|volume=63|issue=3|doi=10.2307/415004}}</ref> The empirical basis of poverty of the stimulus arguments has been challenged by [[Geoffrey Pullum]] and others, leading to back-and-forth debate in the [[language acquisition]] literature.<ref name="PullumScholz">{{cite journal|last1=Pullum|first1=Geoff|author-link1=Geoff Pullum|last2=Scholz|first2=Barbara|author-link2=Barbara Scholz|date=2002|title=Empirical assessment of stimulus poverty arguments|journal=The Linguistic Review|volume=18|issue=1–2|pages=9–50|doi=10.1515/tlir.19.1-2.9}}</ref><ref name="LegateYang">{{cite journal|last1=Legate|first1=Julie Anne|author-link1=Julie Anne Legate|last2=Yang|first2=Charles|author-link2=Charles Yang (linguist)|date=2002|title=Empirical re-assessment of stimulus poverty arguments|journal=The Linguistic Review|volume=18|issue=1–2|pages=151-162|doi=10.1515/tlir.19.1-2.9|url=https://www.ling.upenn.edu/~ycharles/papers/tlr-final.pdf}}</ref> Recent work has also suggested that some [[recurrent neural network]] architectures are able to learn hierarchical structure without an explicit constraint.<ref>{{cite journal|last1=McCoy|first1=R.

Within generative grammar, there are a variety of theories about what universal grammar consists of. One notable hypothesis proposed by [[Hagit Borer]] holds that the fundamental syntactic operations are universal and that all variation arises from different [[feature (linguistics)|feature]]-specifications in the [[mental lexicon|lexicon]].<ref name="PesetskyUG"/><ref>{{cite encyclopedia|title=Parameters|encyclopedia=The Oxford Handbook of Linguistic Minimalism|year=2012|last= Gallego|first=Ángel|editor-last=Boeckx|editor-first=Cedric|publisher=Oxford University Press|doi=10.1093/oxfordhb/9780199549368.013.0023}}</ref> On the other hand, a strong hypothesis adopted in some variants of [[Optimality Theory]] holds that humans are born with a universal set of constraints, and that all variation arises from differences in how these constraints are ranked.<ref name="PesetskyUG"/><ref name ="McCarthyOT">{{cite book|last=McCarthy|first=John|year=1992|title=Doing optimality theory|publisher=Wiley|pages=1-3|isbn=978-1-4051-5136-8}}</ref> In a 2002 paper, [[Noam Chomsky]], [[Marc Hauser]] and [[W. Tecumseh Fitch]] proposed that universal grammar consists solely of the capacity for hierarchical phrase structure.<ref>{{cite journal|last1=Hauser|first1=Marc|author-link1=Marc Hauser|last2=Chomsky|first2=Noam|author-link2=Noam Chomsky|last3=Fitch|first3=W.

In day-to-day research, the notion that universal grammar exists motivates analyses in terms of general principles. As much as possible, facts about particular languages are derived from these general principles rather than from language-specific stipulations.<ref name ="WasowHandbookUniversality"/>

== Subfields ==

Research in generative grammar spans a number of subfields. These subfields are also studied in non-generative approaches.

=== Syntax ===

Syntax studies the rule systems which combine smaller units such as [[morphemes]] into larger units such as [[phrase]]s and [[sentence (linguistics)|sentence]]s.<ref>{{Cite book |last=Carnie|first=Andrew|title=Syntax: A Generative Introduction|author-link=Andrew Carnie|publisher=Wiley-Blackwell|year=2002|isbn=978-0-631-22543-0|page=25}}</ref> Within generative syntax, prominent approaches include [[Minimalist program|Minimalism]], [[Government and binding theory]], [[Lexical Functional Grammar|Lexical-functional grammar]] (LFG), and [[Head-driven phrase structure grammar]] (HPSG).<ref name=carnie_p5/>

=== Phonology ===

Phonology studies the rule systems which organize linguistic sounds. For example, research in phonology includes work on [[phonotactic]] rules which govern which [[phonemes]] can be combined, as well as those that determine the placement of [[stress (linguistics)|stress]], [[tone (linguistics)|tone]], and other [[suprasegmental]] elements.<ref name = "ClementsPhonology">{{cite encyclopedia|title=Phonology|encyclopedia=The MIT encyclopedia of the cognitive sciences|year=1999|last=Clements|first=Nick|author-link=Nick Clements|editor-last1=Wilson|editor-first1=Robert|editor-last2=Keil|editor-first2=Frank|publisher=MIT Press|doi=10.7551/mitpress/4660.003.0026 |pages=639-641}}</ref> Within generative grammar, a prominent approach to phonology is [[Optimality Theory]].<ref name ="McCarthyOT"/>

=== Semantics ===

Semantics studies the rule systems that determine expressions' meanings. Within generative grammar, semantics is  a species of [[formal semantics (natural language)|formal semantics]], providing [[compositionality|compositional]] models of how the [[denotation]]s of sentences are computed on the basis of the meanings of the individual [[morpheme]]s and their syntactic structure.<ref name= "H&K">{{cite book|author1=Irene Heim|author2=Angelika Kratzer|title=Semantics in generative grammar|year=1998|publisher=Wiley-Blackwell|isbn=978-0-631-19713-3}}</ref>

=== Music ===

Generative grammar has been applied to [[music theory]] and [[musical analysis|analysis]] since the 1980s.<ref>{{cite journal|last1=Baroni|first1=Mario|last2=Maguire|first2=Simon|last3=Drabkin|first3=William|year=1983|title=The Concept of Musical Grammar|journal=Music Analysis|volume=2|issue=2|pages=175-208|doi=10.2307/854248}}</ref> One notable approach is [[Fred Lerdahl]] and [[Ray Jackendoff]]'s [[Generative theory of tonal music]], which formalized and extended ideas from [[Schenkerian analysis]].<ref>{{cite book|last=Lerdahl|first=Fred|author2=Ray Jackendoff|title=A Generative Theory of Tonal Music|url=https://archive.org/details/generativetheory0000lerd|publisher=MIT Press|year=1983|isbn=978-0-262-62107-6}}</ref> 

=== Biolinguistics ===

Recent work in generative-inspired [[biolinguistics]] has proposed that universal grammar consists solely of syntactic [[recursion]], and that it arose recently in humans as the result of a random genetic mutation.<ref name="Berwick&Chomsky_2015">{{cite book |last1=Berwick |first1=Robert |last2=Chomsky |first2=Noam |author-link2=Noam Chomsky |title=Why Only Us: Language and Evolution |publisher=MIT Press |date=2015 |isbn=978-0262034241}}</ref> Generative-inspired biolinguistics has not uncovered any particular genes responsible for language.

Formalisms based on this convention were constructed in the 1950s by [[Zellig Harris]] and [[Charles Hockett]]. These gave rise to modern generative grammar.<ref name=Seuren_1998>{{cite book|author=Seuren, Pieter A.

As a distinct research tradition, generative grammar began in the late 1950s with the work of [[Noam Chomsky]].<ref>{{cite book|last=Newmeyer|first=Frederick|year=1986|title=Linguistic Theory in America|publisher=Academic Press|pages=17-18|isbn=0-12-517152-8}}</ref> However, its roots include earlier [[Structuralism|structuralist]] approaches such as [[glossematics]] which themselves had older roots, for instance in the work of the ancient Indian grammarian [[Pāṇini]].<ref name="Koerner_1978">{{cite book|last=Koerner|first=E.

The initial version of generative syntax was called [[transformational grammar]]. In transformational grammar, rules called transformations mapped a level of representation called [[deep structure]]s to another level of representation called surface structure. The semantic interpretation of a sentence was represented by its deep structure, while the surface structure provided its pronunciation. For example, an active sentence such as "The doctor examined the patient" and "The patient was examined by the doctor", had the same deep structure. The difference in surface structures arises from the application of the passivization transformation, which was assumed to not affect meaning. This assumption was challenged in the 1960s by the discovery of examples such as "Everyone in the room knows two languages" and "Two languages are known by everyone in the room".<ref>{{Cite journal |last=Heitner |first=Reese |date=2003-10-03 |title=An Integrated Theory of Linguistic Descriptions [1964] |url=https://doi.org/10.1111/1467-9191.00147 |journal=The Philosophical Forum |volume=34 |issue=3-4 |pages=401–416 |doi=10.1111/1467-9191.00147 |issn=0031-806X|url-access=subscription }}</ref>

After the [[Linguistics wars]] of the late 1960s and early 1970s, Chomsky developed a revised model of syntax called [[Government and binding theory]], which eventually grew into [[Minimalist program|Minimalism]]. In the aftermath of those disputes, a variety of other generative models of syntax were proposed including [[relational grammar]], [[Lexical Functional Grammar|Lexical-functional grammar]] (LFG), and [[Head-driven phrase structure grammar]] (HPSG).<ref>{{Citation |last=Sadler |first=Louisa |title=Morphology in Lexical-Functional Grammar and Head-driven Phrase Structure Grammar |date=2018-12-13 |work=The Oxford Handbook of Morphological Theory |pages=211–243 |editor-last=Audring |editor-first=Jenny |url=https://academic.oup.com/edited-volume/34505/chapter/292751429 |access-date=2025-05-08 |publisher=Oxford University Press |language=en |doi=10.1093/oxfordhb/9780199668984.013.17 |isbn=978-0-19-966898-4 |last2=Nordlinger |first2=Rachel |editor2-last=Masini |editor2-first=Francesca|url-access=subscription }}</ref> 

Generative phonology originally focused on [[rewriting|rewrite rules]], in a system commonly known as ''SPE Phonology'' after the 1968 book [[The Sound Pattern of English]] by Chomsky and [[Morris Halle]]. In the 1990s, this approach was largely replaced by [[Optimality theory]], which was able to capture generalizations called [[conspiracy (phonology)|conspiracies]] which needed to be stipulated in SPE phonology.<ref name ="McCarthyOT"/>

Semantics emerged as a subfield of generative linguistics during the late 1970s, with the pioneering work of [[Richard Montague]]. Montague proposed a system called [[Montague grammar]] which consisted of interpretation rules mapping expressions from a bespoke model of syntax to formulas of [[intensional logic]]. Subsequent work by [[Barbara Partee]], [[Irene Heim]], [[Tanya Reinhart]], and others showed that the key insights of Montague Grammar could be incorporated into more syntactically plausible systems.<ref name="parteebaltic">{{cite journal|last1=Partee|first1=Barbara|year=2011|title=Formal semantics: Origins, issues, early impact.|journal=The Baltic International Yearbook of Cognition, Logic and Communication|volume=6|citeseerx=10.1.1.826.5720}}</ref><ref>{{cite encyclopedia |last1=Crnič|first1=Luka|last2=Pesetsky|first2=David|last3=Sauerland|first3=Uli|editor-last1= Crnič|editor-first1= Luka|editor-last2=Sauerland|editor-first2=Uli|encyclopedia=The art and craft of semantics: A Festschrift for Irene Heim|title=Introduction: Biographical Notes |url=https://semanticsarchive.net/Archive/jZiNmM4N/CrnicPesetskySauerland.pdf|year=2014}}</ref>
