ABSTRACT
One of the leading ideas in Montague grammar, but not only in Montague grammar, has been the principle of compositional interpretation, which we may paraphrase by the slogan: "The meaning of an expression is a function of the meanings of its parts". If this principle is indeed a design feature of natu ral language, then there is a tight parallelism between syntactic structures on the one hand and semantic structures on the other hand.
