COMPOSITIONALITY IN FOCUS.

It is held by many grammarians that the relation of syntax and semantics is characterized by the Fregean principle of compositionality. The principle can be stated in various ways. In this article, the following formulation is adopted: the literal meaning of an expression is uniquely determined by the literal meanings of its subexpressions and their mode of composition. And the author believes that the validity of the formulation is beyond doubt and thus any grammar, whether organized to reflect it directly or not, may ultimately be required to satisfy it. And one of the systems that are precisely designed to reflect the principle is Montague Grammar.
