Generative grammar has been under development since the late 1950s, and has undergone many changes in the types of rules and representations that are used to predict grammaticality. In tracing the historical development of ideas within generative grammar, it is useful to refer to various stages in the development of the theory.

Standard Theory (1957–1965)

The so-called Standard Theory corresponds to the original model of generative grammar laid out in Chomsky (1965).

A core aspect of Standard Theory is a distinction between two different representations of a sentence, called Deep structure
Deep structure
In linguistics, specifically in the study of syntax in the tradition of generative grammar , the deep structure of a linguistic expression is a theoretical construct that seeks to unify several related structures. For example, the sentences "Pat loves Chris" and "Chris is loved by Pat" mean...

Extended Standard Theory (1965–1973)

The so-called Extended Standard Theory was formulated in the late 1960s to early 1970s. Features are:
  • syntactic constraints
  • generalized phrase structures (X-bar theory

Revised Extended Standard Theory (1973–1976)

It contains

Context-free grammars

Generative grammars can be described and compared with the aid of the Chomsky hierarchy

Within the field of computer science, specifically in the area of formal languages, the Chomsky hierarchy is a containment hierarchy of classes of formal grammars....

 proposed by Noam Chomsky in the 1950s. This sets out a series of types of formal grammars with increasing expressive power. Among the simplest types are the regular grammar
Regular grammar
In theoretical computer science, a regular grammar is a formal grammar that describes a regular language.- Strictly regular grammars :A right regular grammar is a formal grammar such that all the production rules in P are of one of the following forms:# B → a - where B is a non-terminal in N and...

s (type 3); Chomsky claims that regular grammars are not adequate as models for human language, because all human languages allow the center-embedding of strings within strings.

At a higher level of complexity are the context-free grammar
Context-free grammar
In formal language theory, a context-free grammar is a formal grammar in which every production rule is of the formwhere V is a single nonterminal symbol, and w is a string of terminals and/or nonterminals ....

s (type 2). The derivation of a sentence by a grammar can be depicted as a derivation tree
Tree structure
A tree structure is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the classic representation resembles a tree, even though the chart is generally upside down compared to an actual tree, with the "root" at the top and the...

. Linguists working in generative grammar often view such derivation trees as a primary object of study. According to this view, a sentence is not merely a string of words, but rather a tree with subordinate and superordinate branches connected at nodes.

Essentially, the tree model works something like this example, in which S is a sentence, D is a determiner, N a noun
Noun
In linguistics, a noun is a member of a large, open lexical category whose members can occur as the main word in the subject of a clause, the object of a verb, or the object of a preposition .Lexical categories are defined in terms of how their members combine with other kinds of...

 and VP a verb phrase
Verb phrase
In linguistics, a verb phrase or VP is a syntactic unit composed of at least one verb and the dependents of that verb. One can distinguish between two types of VPs, finite VPs and non-finite VPs . While phrase structure grammars acknowledge both, dependency grammars reject the existence of a...

:
The resulting sentence could be The dog ate the bone. Such a tree diagram is also called a phrase marker. They can be represented more conveniently in text form, (though the result is less easy to read); in this format the above sentence would be rendered as:

[S [NP [D The ] [N dog ] ] [VP [V ate ] [NP [D the ] [N bone ] ] ] ]

Chomsky has argued that phrase structure grammars are also inadequate for describing natural languages, and has formulated the more complex system of transformational grammar

Grammaticality judgments

When generative grammar was first proposed, it was widely hailed as a way of formalizing the implicit set of rules a person "knows" when they know their native language and produce grammatical utterances in it (grammaticality

 intuitions). However Chomsky has repeatedly rejected that interpretation; according to him, the grammar of a language is a statement of what it is that a person has to know in order to recognize an utterance as grammatical, but not a hypothesis about the processes involved in either understanding or producing language.
