Book excerpt: In the modular design of generative theory the syntax–semantics interface has accounted all along for meanings at the level of Logical Form. The syntax–pragmatics interface, on the other hand, is the result of what one may call the 'pragmatic turn' in the linguistic theory, where content is partitioned into given and new information. In other words, the structural division of the clause has been subjected to criteria of information, or discourse structure. Both interfaces require a structurally descriptive inventory whose specific shapes can be motivated on theory-internal grounds only. The present collection of original articles develops the concept of these interfaces further. The papers in the first section focus on the syntax–semantics interface, those in the second section on the syntax–pragmatics interface.
