In Autolexical Syntax, Jerrold M. Sadock argues for a radical departure from the derivational model of grammar that has prevailed in linguistics for thirty years. He offers an alternative theory in which the various components of grammar--in particular syntax, semantics, and morphology--are viewed as fully autonomous descriptive devices for various parallel dimensions of linguistic representation. The lexicon in this theory forges the connection between autonomous representations in that a typical lexeme plays a role in all three of the major components of the grammar. Sadock's principal innovation is the postulation of a uniform set of interface conditions that require the several orthogonal representations of a single natural language expression to match up in certain ways. Through a detailed application of his theory to the twin morphosyntactic problems of cliticization and incorporation, Sadock shows that very straightforward accounts are made possible by the nonderivational model. He demonstrates the empirical success of these accounts by examining more than two dozen morphosyntactic problems in almost as many languages. Autolexical Syntax will be of interest to those in the fields of theoretical grammar, particularly concerned with the problems of morphology and syntax, as well as philosophers of language, logicians, lexicographers, psychologists of language, and computer scientists.
