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.*
