In this technical monograph, Paul Postal deals with several crucial issues that have been treated only marginally in the development of current linguistic theorizing. He focuses on three problems in syntactic theory that are connected to "extraction" - the occurrence of an element in a position distinct from its unmarked locus in simple clauses. He examines a largely ignored body of systematic contrasts among known extraction types, the status of the Coordinate Structure Constraint, and the phenomenon of Right Node Raising.
