Syntax
Works on grammar were being written long before modern syntax came about; the Aṣṭādhyāyī of Pāṇini is often cited as an example of a pre-modern work that approaches the sophistication of a modern syntactic theory.[1] In the West, the school of thought that came to be known as "traditional grammar" began with the work of Dionysius Thrax.
[edit] Modern theories
There are a number of theoretical approaches to the discipline of syntax. Many linguists (e.g. Noam Chomsky) see syntax as a branch of biology, since they conceive of syntax as the study of linguistic knowledge as embodied in the human mind. Others (e.g. Gerald Gazdar) take a more Platonistic view, since they regard syntax to be the study of an abstract formal system.[3] Yet others (e.g. Joseph Greenberg) consider grammar a taxonomical device to reach broad generalizations across languages. Some of the major approaches to the discipline are listed below.
[edit] Generative grammar
Main article: Generative grammar
The hypothesis of generative grammar is that language is a structure of the human mind. The goal of generative grammar is to make a complete model of this inner language (known as i-language). This model could be used to describe all human language and to predict the grammaticality of any given utterance (that is, to predict whether the utterance would sound correct to native speakers of the language). This approach to language was pioneered by Noam Chomsky. Most generative theories (although not all of them) assume that syntax is based upon the constituent structure of sentences. Generative grammars are among the theories that focus primarily on the form of a sentence, rather than its communicative function.
Government and binding theory (GB) (revised theory in the tradition of TG developed mainly by Chomsky in the 1970s and 1980s).[5]
The Minimalist Program (MP) (revised version of GB published by Chomsky in 1995)[6]
Other theories that find their origin in the generative paradigm are:
Relational grammar (RG) (now largely out of date)
Arc Pair grammar
Generalized phrase structure grammar (GPSG; now largely out of date)
Head-driven phrase structure grammar (HPSG)
Lexical-functional grammar (LFG)
Categorial grammar is an approach that attributes the syntactic structure not to rules of grammar, but to the properties of the syntactic categories themselves. For example, rather than asserting that sentences are constructed by a rule that combines a noun phrase (NP) and a verb phrase (VP) (e.g. the phrase structure rule S → NP VP), in categorial grammar, such principles are embedded in the category of the head word itself. So the syntactic category for an intransitive verb is a complex formula representing the fact that the verb acts as a functor which requires an NP as an input and produces a sentence level structure as an output. This complex category is notated as (NPS) instead of V. NPS is read as " a category that searches to the left (indicated by ) for a NP (the element on the left) and outputs a sentence (the element on the right)". The category of transitive verb is defined as an element that requires two NPs (its subject and its direct object) to form a sentence. This is notated as (NP/(NPS)) which means "a category that searches to the right (indicated by /) for an NP (the object), and generates a function (equivalent to the VP) which is (NPS), which in turn represents a function that searches to the left for an NP and produces a sentence).
[edit] Dependency grammar
Dependency grammar is a different type of approach in which structure is determined by the relations (such as grammatical relations) between a word (a head) and its dependents, rather than being based in constituent structure. For example, syntactic structure is described in terms of whether a particular noun is the subject or agent of the verb, rather than describing the relations in terms of phrases.
Word grammar
Operator Grammar
Theoretical approaches to syntax that are based upon probability theory are known as stochastic grammars. One common implementation of such an approach makes use of a neural network or connectionism. Some theories based within this approach are:
Stochastic context-free grammar
Functionalist theories, although focused upon form, are driven by explanation based upon the function of a sentence (i.e. its communicative function). Some typical functionalist theories include:
Prague Linguistic Circle
Systemic functional grammar
Cognitive grammar
Construction grammar (CxG)
Role and reference grammar (RRG)
Emergent grammar
