Regularity and Idiomaticity in Grammatical Constructions: The Case of Let Alone

Through the detailed investigation of the syntax, semantics, and pragmatics of one grammatical construction, that containing the conjunction let alone , we explore the view that the realm of idiomaticity in a language includes a great deal that is productive, highly structured, and worthy of serious grammatical investigation. It is suggested that an explanatory model of grammar will include principles whereby a language can associate semantic and pragmatic interpretation principles with syntactic configurations larger and more complex than those definable by means of single phrase structure rules.
