- The term phrase structure grammar was originally introduced by Noam Chomsky as the term for grammars as defined by phrase structure rules,  i.e. rewrite rules of the type studied previously by Emil Post and Axel Thue (see Post canonical systems). Some authors, however, reserve the term for more restricted grammars in the Chomsky hierarchy: context-sensitive grammars, or context-free grammars. In a broader sense, phrase structure grammars are also known as constituency grammars. The defining trait of phrase structure grammars is thus their adherence to the constituency relation, as opposed to the dependency relation of dependency grammars.
