The terminology used in English transformational grammar is compiled in this glossary. The glossary catalogs, defines, classifies, documents, and cross-references technical terms from 72 major works published from 1956 to 1969. The selection of terms is based on their technical nature in relation to the theory of transformational grammar or to the application of that theory to English grammar. Terms included in the glossary contain references to such subjects as grammatical theory, syntactic theory, semantic theory, and the philosophy of language. The definition of each term is provided with a complete source in the bibliography. (RS)
