Phrase Structure Grammars
In linguistics and cognitive science, the term 'grammar' refers to the syntax or set of formal rules of a language. These rules govern both the analysis and the production of sentences of a language. Accordingly, phrase structure grammars give us a set of rewrite rules and a series of variables designating grammatical types such as noun phrase, verb phrase, and prepositional phrase.|
Phrase structure grammars enable hierarchical analyses of sentences. Hence, they allow us first to break down a sentence into the components noun phrase and verb phrase; these components can be broken down further and so on until unanalyzable components are reached.
