The term phrase structure grammar was originally introduced by Noam Chomsky as the term for grammar studied previously by Emil Post and Axel Thue (Post canonical systems).Some authors, however, reserve the term for more restricted grammars in the Chomsky hierarchy: context-sensitive grammars or context-free grammars.
A grammar that uses phrase structure rules is a type of phrase structure grammar. Phrase structure rules as they are commonly employed operate according to the constituency relation, and a grammar that employs phrase structure rules is therefore a constituency grammar; as such, it stands in contrast to dependency grammars, which are based on ...
A syntactic category is a syntactic unit that theories of syntax assume. [1] Word classes, largely corresponding to traditional parts of speech (e.g. noun, verb, preposition, etc.), are syntactic categories. In phrase structure grammars, the phrasal categories (e.g. noun phrase, verb phrase, prepositional phrase, etc.) are also syntactic ...
In linguistics, X-bar theory is a model of phrase structure and a theory of syntactic category formation [1] that proposes a universal schema for how phrases are organized. It suggests that all phrases share a common underlying structure, regardless of their specific category ( noun phrase , verb phrase , etc.).
Head-driven phrase structure grammar (HPSG) is a highly lexicalized, constraint-based grammar [1] [2] developed by Carl Pollard and Ivan Sag. [3] [4] It is a type of phrase structure grammar, as opposed to a dependency grammar, and it is the immediate successor to generalized phrase structure grammar.
Emergence of headed combinations: Within the minimalist program, bare phrase structure, described in detail above, accounts for children's first language acquisition better than earlier theories of phrase structure building, such as X-bar theory. This is because, under bare phrase structure, children do not need to account for the intermediate ...
Particularly in early incarnations, transformational syntax adopted the view that phrase structure grammar must be enriched by a transformational grammar, with syntactic rules or syntactic operations that alter the base structures created by phrase structure rules. In more recent theories, including Government and Binding Theory but especially ...
Their book Generalized Phrase Structure Grammar, published in 1985, is the main monograph on GPSG, especially as it applies to English syntax. GPSG was in part a reaction against transformational theories of syntax. In fact, the notational extensions to context-free grammars (CFGs) developed in GPSG are claimed to make transformations redundant ...
