Phrase structure rules are a type of rewrite rule used to describe a given language's syntax and are closely associated with the early stages of transformational grammar, proposed by Noam Chomsky in 1957. [1] They are used to break down a natural language sentence into its constituent parts, also known as syntactic categories, including both ...
In linguistics, phrase structure grammars are all those grammars that are based on the constituency relation, as opposed to the dependency relation associated with dependency grammars; hence, phrase structure grammars are also known as constituency grammars. [2] Any of several related theories for the parsing of natural language qualify as ...
The phrase structure rules are used for expanding grammatical categories and for substitutions. These yield a string of morphemes. A transformational rule "operates on a given string ... with a given constituent structure and converts it into a new string with a new derived constituent structure." [8] It "may rearrange strings or may add or ...

In linguistics, grammar is the set of rules for how a natural language is structured, as demonstrated by its speakers or writers. Grammar rules may concern the use of clauses, phrases, and words. The term may also refer to the study of such rules, a subject that includes phonology, morphology, and syntax, together with phonetics, semantics, and ...
The base in the syntactic component functions as follows: In the first step, a simple set of phrase structure rules generate tree diagrams (sometimes called Phrase Markers) consisting of nodes and branches, but with empty terminal nodes; these are called "pre-lexical structures". In the second step, the empty terminal nodes are filled with ...
In terms of phrase structure rules, phrasal categories can occur to the left of the arrow while lexical categories cannot, e.g. NP → D N. Traditionally, a phrasal category should consist of two or more words, although conventions vary in this area. X-bar theory, for instance, often sees individual words corresponding to phrasal categories ...
Grammatical modifier. In linguistics, a modifier is an optional element in phrase structure or clause structure [1] which modifies the meaning of another element in the structure. For instance, the adjective "red" acts as a modifier in the noun phrase "red ball", providing extra details about which particular ball is being referred to.
