Metonymy is refering to one entity by describing a functionally related entity. When this is formalized in an "Interpretation as Abduction" framework, it can be seen that an isomorphic process solves a number of problems that have hitherto been viewed as syntactic. In these cases, the coercion function associated with the metonymy comes from material that is explicit in the sentence. For example, in ``John smokes an occasional cigarette'', it is the smoking rather than the explicit argument of ``occasional'', the cigarette, that is occasional; there is a coercion from the cigarette to the smoking event, where the coercion relation is provided by the ``smokes'' predication itself. Other phenomena analyzed in this manner are extraposed modifiers, container nouns, the collective-distributive ambiguity for some plural noun phrases, small clauses in disguise such as ``This country needs literate citizens'', and the assertion of grammatically presupposed material. These examples lie on the boundaries between syntax, semantics and pragmatics, and illustrate the utility of a framework in which the three areas are modelled in a uniform fashion.
