Syntactic Structures is a seminal work in linguistics by American linguist Noam Chomsky, originally published in 1957. A short monograph of about a hundred pages, it is recognized as one of the most significant and influential linguistic studies of the 20th century. It contains the now-famous sentence "Colorless green ideas sleep furiously", which Chomsky offered as an example of a grammatically correct sentence that has no discernible meaning, thus arguing for the independence of syntax (the study of sentence structures) from semantics (the study of meaning).From :"...such semantic notions as reference, significance, and synonymity played no role in the discussion."
Based on lecture notes he had prepared for his students at the Massachusetts Institute of Technology in the mid-1950s, Syntactic Structures was Chomsky's first book on linguistics and reflected the contemporary developments in early generative grammar. In it, Chomsky introduced his idea of a transformational generative grammar, succinctly synthesizing and integrating the concepts of transformation (pioneered by his mentor Zellig Harris, but used in a precise and integrative way by Chomsky), morphophonemic rules (introduced by Leonard Bloomfield) and an item-and-process style of grammar description (developed by Charles Hockett). Here, Chomsky's approach to syntax is fully Formal science (based on symbols and rules). At its base, Chomsky uses phrase structure rules,From : "In §§3-7 we outlined the development of some fundamental linguistic concepts in purely formal terms." which break down sentences into smaller parts. These are combined with a new kind of rules which Chomsky called "transformations". This procedure gives rise to different sentence structures. Chomsky stated that this limited set of rules "generates"Here, "generate" means giving a clear structural description of each sentence. In , Chomsky writes that "When we speak of a grammar as generating a sentence with a certain structural description, we mean simply that the grammar assigns this structural description to the sentence." all and only the grammatical sentences of a given language, which are infinite in number (not too dissimilar to a notion introduced earlier by Danish linguist Louis Hjelmslev). Although not explicitly stated in the book itself, this way of study was later interpreted to have valued language's Innatism place in the mind over language as learned Behaviorism,According to , Hjelmslev and other European linguists, in contrast, had considered the generative calculus as perfectly non-psychological.

Written when Chomsky was still an unknown scholar, writes: "Chomsky was at the time an unknown 28-year-old who taught language classes at MIT" Syntactic Structures had a major impact on the study of philosophy, psychology and mental processes, becoming an influential work in the formation of the field of cognitive science. It also significantly influenced research on computer science and the neuroscience.See the "Reception" section of this article. The importance of Syntactic Structures lies in Chomsky's persuasion for a biological perspective on language at a time when it was unusual, and in the context of formal linguistics where it was unexpected. The book led to Chomsky's eventual recognition as one of the founders of what is now known as sociobiology. Some specialists have questioned Chomsky's theory, believing it is wrong to describe language as an ideal system. They also say it gives less value to the empiricism.See the "Criticisms" section of this article. Nevertheless, Syntactic Structures is credited to have changed the course of linguistics in general and American linguistics in particular in the second half of the 20th century.
For his thesis, Chomsky set out to apply Harris's methods to Hebrew. Following Harris's advice, he studied logic, philosophy, and mathematics. and He found Harris's views on language much like Nelson Goodman's work on philosophical systems.Especially Goodman's work on constructional systems and on the inadequacy of inductive approaches. See . writes: "Chomsky has said that he was convinced from his days as a student of Goodman's that there is no inductive learning." Chomsky was also influenced by the works of W. V. O. Quine writes: "Quine's critiques of logical empiricism also gave some reason to believe that a might be a plausible one." and Rudolf Carnap. states that among non-American philosophers, it was only Rudolf Carnap whom Chomsky read as a student (p. 3) writes that "It is well known that Carnap's post-Aufbau work (especially Logische Syntax der Sprache) influenced Chomsky directly to some extent." Quine showed that one cannot completely verify the meaning of a statement through observations. Carnap had developed a formal theory of language. It used symbols and rules that did not refer to meaning.
From there on, Chomsky tried to build a grammar of Hebrew. Such a grammar would generate the Phonetics or sound forms of sentences. To this end, he organized Harris's methods in a different way. states: "The most significant discontinuity between is Chomsky's inversion of Harris's analytic procedures." To describe sentence forms and structures, he came up with a set of recursive rules. These are rules that refer back to themselves. He also found that there were many different ways of presenting the grammar. He tried to develop a method to measure how simple a grammar is. writes: "Echoing Goodman's pro-simplicity arguments ... the task of creating ... a simplicity measure is precisely the one Chomsky sets for himself in Chapter 4 of LSLT." For this, he looked for "generalizations" among the possible sets of grammatical rules. states: "We want the reduction of the number of elements and statements, any generalizations ... to increase the total simplicity of the grammar" Chomsky completed his undergraduate thesis The Morphophonemics of Modern Hebrew in 1949. He then published a revised and expanded version of it as his master's thesis in 1951.
In 1951, Chomsky became a Junior Fellow at Harvard University. There, he tried to build an all-formal linguistic theory.Before Chomsky, Israeli mathematician and linguist Yehoshua Bar-Hillel had already shown in that formal languages and methods used in symbolic logic can be adapted to analyze human languages. It was a clear break with the existing tradition of language study. In 1953, Chomsky published his first paper as a scholar. In it he tried to adapt the symbol-based language of logic to describe the syntax of a human language. During his fellowship, Chomsky organized all his ideas into a huge manuscript. It was around 1,000 typewritten pages long. He gave it the title The Logical Structure of Linguistic Theory ( LSLT).
In 1955, Chomsky found a job at MIT. He worked there as a linguist in the mechanical translation project. The same year he submitted his doctoral dissertation to the University of Pennsylvania. The university granted him a Ph.D. for his thesis Transformational Analysis. In fact, it was just the ninth chapter of LSLT.
When this work is done to a satisfactory level, it will also become possible to predict all the grammatical sentences of a given language:
Hjelmslev also points out that an algorithmic description of a language could generate an infinite number of products from a finite number of primitive elements:
These are logical consequences of the mathematical systems proposed by David Hilbert and Rudolf Carnap which were first adopted into linguistics by Hjelmslev whose ideas are reiterated by Chomsky:
Chomsky likewise states that a recursive device such as closed loops would allow the grammar to generate an infinite number of sentences.
Although the Bloomfieldian school of early to mid-20th century linguists were nicknamed 'American structuralists', they essentially rejected the basic tenets of structuralism: that linguistic form is explained through meaning, and that linguistics belongs to the domain of sociology.
Chomsky, like Harris and other American linguists, agreed that there is no causal link from semantics to syntax.
How to translate this idea into a scientific statement remained a vexing issue in American linguistics for decades. Harris and Rulon Wells justified analyzing the object as part of the verb phrase per 'economy'; but this term, again, merely suggested the perceived 'easiness' of the practice.
In Syntactic Structures, Chomsky changes the meaning of Hjelmslev's principle of arbitrariness which meant that the generative calculus is merely a tool for the linguist and not a structure in reality. David Lightfoot however points out in his introduction to the second edition that there were few points of true interest in Syntactic Structures itself, and the eventual interpretations that the rules or structures are 'cognitive', innate, or biological would have been made elsewhere, especially in the context of a debate between Chomsky and the advocates of behaviorism. But decades later, Chomsky makes the clear statement that syntactic structures, including the object as a dependent of the verb phrase, are caused by a genetic mutation in humans.
Mouton & Co. was a Dutch publishing house based in The Hague. They had gained academic reputation by publishing works on Slavic Studies since 1954. Particularly, they had published works by linguists Nicolaas van Wijk and Roman Jakobson. Soon they started a new series called Janua Linguarum or the "Gate of Languages." It was intended to be a series of "small monographs" on general linguistics.The series's editor van Schooneveld is quoted thus in : "I had originally conceived of the Janua as a series of small monographs of the size of a large article, too interesting to get drowned in a periodical amongst other contributions and to be lost to oblivion by the current of time." The first volume of the Janua Linguarum series was written by Roman Jakobson and Morris Halle. It was called Fundamentals of Language, published in 1956. Chomsky had already met Jakobson, a professor at Harvard University, during his fellowship years. Halle was Chomsky's graduate classmate at Harvard and then a close colleague at MIT. In 1956, Chomsky and Halle collaborated to write an article on phonology, published in a festschrift for Jakobson. The festschrift was published by Mouton in 1956.
Cornelis van Schooneveld was the editor of the Janua Linguarum series at Mouton. He was a Dutch linguist and a direct student of Jakobson. He was looking for monographs to publish for his series. Consequently, he visited Chomsky at MIT in 1956. With Morris Halle's (and possibly Jakobson's) mediation, Chomsky showed van Schooneveld his notes for his introductory linguistics course for undergraduate students. Van Schooneveld took an interest in them. He offered to publish an elaborate version of them at Mouton, to which Chomsky agreed.Chomsky is quoted in saying: "It Syntactic was course notes for an undergraduate course at MIT. Van Schooneveld a showed up here once and took a look at some of my course notes from the undergraduate course I was teaching and said I ought to publish it." In (), Chomsky recounted: "At the time Mouton was publishing just about anything, so they decided they'd publish it along with a thousand other worthless things that were coming out. That's the story of Syntactic Structures: course notes for undergraduate science students published by accident in Europe." The publication of Syntactic structures is also discussed in and .
Chomsky then prepared a manuscript of the right size (no longer than 120 pages)According to , Peter de Ridder, the managing director of Mouton, wrote to van Schooneveld that "new titles in the series should no bigger than about 120 pages." that would fit the series. After revising an earlier manuscript, Chomsky sent a final version in the first week of August in 1956 to van Schooneveld.
A scan of Chomsky's own typewritten letter dated 5 August 1956 to Mouton editor Cornelis van Schooneveld can be found in . This letter accompanied the final version of the manuscript. The editor had Chomsky rename the book's title to Syntactic Structures for commercial purposes. mentions De Ridder writing to van Schooneveld that "I am convinced that the book will sell well with this title." The book was also pre-ordered in big numbers by MIT. These gave more incentives to Mouton to publish the book. Mouton finally published Chomsky's monograph titled Syntactic Structures in the second week of February 1957.
Soon after the book's first publication, Bernard Bloch, editor of the prestigious journal Language, gave linguist Robert Benjamin Lees, a colleague of Chomsky's at MIT, the opportunity to write a review of the book. Lees's very positive remarks that Lees's review was "hyperbolic", his language "loaded" and refers to Lees as "Chomsky's Huxley", referring to the proselytizing "bulldog" role played by Thomas Henry Huxley in defense of Charles Darwin's theories on evolution. considers Lees to be "Chomsky's explicator". Chomsky himself considers Lees's review "provocative." () essay-length review appeared in the July–September 1957 issue of Language. This early but influential review made Syntactic Structures visible on the linguistic research landscape. Shortly thereafter the book created a putative "Paradigm shift" in the discipline. remarked that "a revolution of the kind Kuhn describes has recently taken place in linguistics – dating from the publication of Chomsky's Syntactic Structures in 1957". According to : "What has happened in linguistics since Chomsky appeared on the scene almost perfectly fits Kuhn's description of how a scientific revolution works." writes that "Chomsky's revolution followed fairly closely the general pattern described in Thomas Kuhn's The Structure of Scientific Revolutions". Later, some linguists began to question whether this was really a revolutionary breakthrough. A critical and elaborate account is given in Chomskyan (R)evolutions. Although Frederick Newmeyer states that "the publication of Syntactic structures has had profound effects, both intellectually for the study of language and sociologically for the field of linguistic", John Searle, three decades after his original review, wrote that "Judged by the objectives stated in the original manifestoes, the revolution has not succeeded. Something else may have succeeded, or may eventually succeed, but the goals of the original revolution have been altered and in a sense abandoned." As for LSLT, it would be 17 more years before it saw publication.
Syntactic Structures was the fourth book in the Janua Linguarum series. It was the series's bestselling book. It was reprinted 13 times until 1978. In 1962, a Russian translation by Konstantin Ivanovich Babisky, titled Синтакси́ческие структу́ры ( Sintaksychyeskiye Struktury), was published in Moscow. In 1963, Yasuo Isamu wrote a Japanese translation of the book, named . In 1969, a French translation by Michel Braudeau, titled Structures Syntaxiques, was published by Éditions du Seuil in Paris. In 1973, Mouton published a German translation by Klaus-Peter Lange, titled Strukturen der Syntax. The book has also been translated into Korean language, Spanish language, Italian language, Czech language, Serbo-Croatian and Swedish language languages.
Chomsky then analyzes further about the basis of "grammaticality." He shows three ways that do not determine whether a sentence is grammatical or not. First, a grammatical sentence need not be included in a corpus. Secondly, it need not be meaningful. Finally, it does not have to be statistically probable. Chomsky shows all three points using a nonsensical sentence "Colorless green ideas sleep furiously." He writes that the sentence is instinctively "grammatical" to a native English speaker. But it is not included in any known corpus at the time and is neither meaningful nor statistically probable.
Chomsky concludes that "grammar is autonomous and independent of meaning." He adds that "probabilistic models give no particular insight into some of the basic problems of syntactic structure."
Chomsky also borrowed the term "generative" from a previous work of mathematician Emil Post.In , Chomsky writes that he was "following a familiar technical use of the term "generate," cf. ". In , Chomksy justifies his choice of the term "generate", writing that "the term 'generate' is familiar in the sense intended here in logic, particularly in Post's theory of combinatorial systems. Furthermore, 'generate' seems to be the most appropriate translation for Humboldt's term erzeugen, which he frequently uses, it seems, in essentially the sense here intended. Since this use of the term 'generate' is well established both in logic and in the tradition of linguistic theory." Post wanted to "mechanically derive inferences from an initial axiomatic sentence"., and Chomsky applied Post's work on logical inference to describe sets of strings (sequence of letters or sounds) of a human language. When he says a finite set of rules "generate" (i.e. "recursively enumerate") the set of potentially infinite number of sentences of a particular human language, he means that they provide an explicit, structural description of those sentences.In , Chomsky writes that "by a generative grammar I mean simply a system of rules that in some explicit and well-defined way assigns structural descriptions to sentences."
Chomsky then shows that a grammar which analyzes sentences up to the phrase structure level contains many constructional homonymities at the phrase structure level where the resulting ambiguities need to be explained at a higher level. Then he shows how his newly invented "transformational level" can naturally and successfully function as that higher level. He further claims that any phrase structure grammar which cannot explain these ambiguities as successfully as transformational grammar does must be considered "inadequate".
In particular, Chomsky's analysis of the complex English auxiliary verb system in Syntactic Structures had great rhetorical effect. It combined simple phrase structure rules with a simple transformational rule. This treatment was based entirely on formal simplicity. Various linguists have described it as "beautiful", "powerful", "elegant", "revealing", "insightful", "beguiling" and "ingenious". wrote that “Chomsky’s examples of defects of phrase structure grammar were illustrated simultaneously with the demonstration that grammars containing the more powerful transformational rules can handle the same phenomena in an elegant and revealing manner.”According to , "this apparently curious analysis is rather ingenious" and "the powerful tool of different levels of structure related by transformations was particularly beguiling, since transformations appeared to offer a means of explaining the often amazingly complex relationships between the forms of sentences and their understanding."In his introduction to Syntactic Structures (), American linguist David Lightfoot wrote that "this ingenious transformation...avoided hopelessly complex phrase structure rules and yielded an elegant account... ” According to American linguist Frederick Newmeyer, this particular analysis won many "supporters for Chomsky" and "immediately led to some linguists' proposing generative-transformational analysis of particular phenomena". According to British linguist E. Keith Brown, "the elegance and insightfulness of this account was instantly recognized, and this was an important factor in ensuring the initial success of the transformational way of looking at syntax." American linguist Mark Aronoff wrote that this "beautiful analysis and description of some very striking facts was the rhetorical weapon that drove the acceptance of Chomsky's theory". He added that in Chomsky's treatment of English verbs, "the convergence of theory and analysis provide a description of facts so convincing that it changed the entire field".
Raymond Oenbring, a doctorate in the rhetoric of science, thinks that Chomsky "overstates the novelty" of transformational rules. He "seems to take all the credit for them" even though a version of them had already been introduced by Zellig Harris in a previous work. He writes that Chomsky himself was "cautious" to "display deference" to prevailing linguistic research. His enthusiastic followers such as Lees were, by contrast, much more "confrontational". They sought to drive a "rhetorical wedge" between Chomsky's work and that of post-Bloomfieldians (i.e. American linguists in the 1940s et 1950s), arguing that the latter does not qualify as linguistic "science".
Another historian of linguistics Frederick Newmeyer considers Syntactic Structures "revolutionary" for two reasons. Firstly, it showed that a Formal language yet non-Empiricism theory of language was possible. Chomsky demonstrated this possibility in a practical sense by formally treating a fragment of English grammar. Secondly, it put syntax at the center of the theory of language. Syntax was recognized as the focal point of language production, in which a finite set of rules can produce an infinite number of sentences. Subsequently, morphology (i.e. the study of structure and formation of words) and phonology (i.e. the study of organization of sounds in languages) were relegated in importance.
American linguist Norbert Hornstein wrote that before Syntactic Structures, linguistic research was overly preoccupied with creating hierarchies and categories of all observable language data. One of the "lasting contributions" of Syntactic Structures is that it shifted the linguistic research methodology to abstract, rationalist theory-making based on contacts with data, which is the "common scientific practice".
In 2015, at New York University conducted experiments to verify if the human brain uses "hierarchical structure building" for processing languages. They measured the magnetic and electric activities in the brains of participants. The results showed that "human brains distinctly tracked three components of the phrases they heard." This "reflected a hierarchy in our Neurolinguistics of linguistic structures: words, phrases, and then sentences—at the same time." These results bore out Chomsky's hypothesis in Syntactic Structures of an "internal grammar mechanism" inside the brain.
Syntactic Structures was included in The 100 Most Influential Books Ever Written, a book on intellectual history by British literary critic and biographer Martin Seymour-Smith published in 1998.
Syntactic Structures was also featured in a list of 100 best English language non-fiction books since 1923 picked by the American weekly magazine Time Magazine.

The generative grammar of Syntactic Structures heralded Chomsky's mentalist perspective in linguistic analysis. Shortly after its publication, in 1959, Chomsky wrote a critical review of B.F. Skinner's Verbal Behavior. Skinner had presented the acquisition of human language in terms of conditioned responses to outside stimuli and reinforcement. Chomsky opposed this Behaviorism model. He argued that humans produce language using separate syntactic and semantic components inside the mind. He presented the generative grammar as a coherent abstract description of this underlying psycholinguistic reality. Chomsky's argument had a forceful impact on psycholinguistic research. It changed the course of the discipline in the following years.According to : "Chomsky's was more powerful that anything ... psycholinguists had heretofore had at their disposal. It was of special interest to these theorists. Many psychologists were quick to attribute generative systems to the minds of speakers and quick to abandon ... Behaviorism."
Syntactic Structures initiated an interdisciplinary dialog between philosophers of language and linguists. American philosopher John Searle called it a "remarkable intellectual achievement" of its time. He compared the book "to the work of Keynes or Freud". He credited it with producing not only a "revolution in linguistics", but also having a "revolutionary effect" on "philosophy and psychology". Chomsky and Willard Van Orman Quine, a stridently anti-mentalistic philosopher of language, debated many times on the merit of Chomsky's linguistic theories. Many philosophers supported Chomsky's idea that natural languages are innate and syntactically rule-governed. They also believed in the existence of rules in the human mind which bind meanings to . The investigation of these rules started a new era in philosophical semantics. writes: "That natural languages are indeed not systematic enough to allow formal treatment ... is ... a complaint that has been leveled against natural languages by philosophers for centuries. The work of Chomsky in generative linguistics apparently inspired much more confidence in philosophers and logicians to assert that perhaps natural languages weren't as unsystematic and misleading as their philosophical predecessors had made them out to be ... at the end of 1960s formal semantics began to flourish." writes: "Recent work by Chomsky and others is doing much to bring the complexities of natural languages within the scope of serious semantic theory".
With its formal and logical treatment of language, Syntactic Structures also brought linguistics and the new field of computer science closer together. Computer scientist Donald Knuth (winner of the Turing Award) recounted that he read Syntactic Structures in 1961 and was influenced by it.From the preface of : "... researchers in linguistics were beginning to formulate rules of grammar that were considerably more mathematical than before. And people began to realize that such methods are highly relevant to the artificial languages that were becoming popular for computer programming, even though natural languages like English remained intractable. I found the mathematical approach to grammar immediately appealing—so much so, in fact, that I must admit to taking a copy of Noam Chomsky's Syntactic Structures along with me on my honeymoon in 1961. During odd moments, while crossing the Atlantic in an ocean liner and while camping in Europe, I read that book rather thoroughly and tried to answer some basic theoretical questions. Here was a marvelous thing: a mathematical theory of language in which I could use a computer programmer's intuition! The mathematical, linguistic, and algorithmic parts of my life had previously been totally separate. During the ensuing years those three aspects became steadily more intertwined; and by the end of the 1960s I found myself a Professor of Computer Science at Stanford University, primarily because of work that I had done with respect to languages for computer programming." Chomsky's "Three models" paper (), published a year prior to the Syntactic Structures and containing many of its ideas, was crucial to the development of the theory of formal languages within computer science. writes:"Papers had a huge, lasting influence on pure computer science" and that they are cited in "virtually every introduction to compiler design". states that "Chomsky's notion of a context-free grammar ... has aided immensely the specification of programming languages."
In 2011, a group of French neuroscientists conducted research to verify if actual brain mechanisms worked in the way that Chomsky suggested in Syntactic Structures. The results suggested that specific regions of the brain handle syntactic information in an abstract way. These are independent from other brain regions that handle semantic information. Moreover, the brain analyzes not just mere strings of words, but hierarchical structures of constituents. These observations validated the theoretical claims of Chomsky in Syntactic Structures.
Criticisms
In his 1964 presidential address to the Linguistic Society of America, American linguist Charles Hockett considered Syntactic Structures one of "only four major breakthroughs in modern linguistics".The other three are Sir William Jones's address to the Asiatic Society in 1786, Karl Verner's Eine Ausnahme der ersten Lautverschiebung in 1875 and Ferdinand de Saussure's Cours de Linguistique Générale in 1916. But he rapidly turned into a fierce critic of Chomskyan linguistics. By 1966, Hockett rejected "Chomsky's frame of reference in almost every detail". In his 1968 book The State of the Art, Hockett writes that Chomsky's main fallacy is that he treats language as a Formal science, well-defined, stable system and proceeds from this idealized abstraction. Hockett believes such an idealization is not possible. He claims that there is no Empiricism that our language faculty is, in reality, a well-defined underlying system. The sources that give rise to language faculty in humans, e.g. physical genetic transmission and cultural transmission, are themselves poorly defined. states: "we must not promote our more or less standardized by-and-large characterization of the language to the status of a monolithic ideal, nor infer that because we can achieve a fixed characterization some such monolithic ideal exists, in the lap of God or in the brain of each individual speaker." Hockett also opposed Chomsky's hypothesis that syntax is completely independent of the study of meaning.
Contrary to Hockett, British linguist Geoffrey Sampson thought that Chomsky's assumptions about a well-defined grammaticality are "justified in practice." It brought syntax "within the purview of scientific description". He considers it a "great positive contribution to the discipline". However, he maintains that Chomsky's linguistics is overly "intuition-based". For him, it relies too much on native speakers' subjective Introspection judgments about their own language. Consequently, language data empirically observed by impersonal third parties are given less importance.
According to Sampson, Syntactic Structures largely owes its good fortune of becoming the dominant theoretical paradigm in the following years to the charisma of Chomsky's intellect. Sampson writes that there are many references in Syntactic Structures to Chomsky's own The Logical Structure of Linguistic Theory (LSLT) in matters regarding the formal underpinnings of Chomsky's approach, but LSLT was not widely available in print for decades. Nevertheless, Sampson's argument runs, Syntactic Structures, albeit "sketchy", derived its "aura of respectability" from LSLT lurking in the background. In turn, the acceptance of Chomsky's future works rested on the success of Syntactic Structures. In the view of British-American linguist Geoffrey K. Pullum, Syntactic Structures boldly claims that "it is impossible, not just difficult" for finite-state devices to generate all grammatical sentences of English, and then alludes to LSLT for the "rigorous proof" of this. But in reality, LSLT does not contain a valid, convincing proof dismissing finite-state devices.
Pullum also remarks that the "originality" of Syntactic Structures is "highly overstated". For him, it "does not properly credit the earlier literature on which it draws". He shows in detail how the approach in Syntactic Structures goes directly back to the work of the mathematical logician Emil Post on formalizing proof. But "few linguists are aware of this, because Post's papers are not cited." Pullum adds that the use of formal to generate probable sentences in language in a Top-down parsing manner was first proposed by Zellig Harris in 1947, ten years before the publication of Syntactic Structures. This is downplayed in Syntactic Structures.
In 1982, Pullum and another British linguist Gerald Gazdar argued that Chomsky's criticisms of context-free phrase structure grammar in Syntactic Structures are either mathematically flawed or based on incorrect assessments of the empirical data. They stated that a purely phrase structure treatment of grammar can explain linguistic phenomena better than one that uses transformations.Versions of such non-transformational phrase structure grammars include Generalized phrase structure grammar (GPSG), Head-driven phrase structure grammar (HPSG) and Lexical functional grammar (LFG).
