Gradual conventionalization of pragmatic inferences

The alternation in Spanish between y and e on the one hand, and u and o in the other, is examined. It is proposed that the standard account under which the choice of one variant over the other is sensitive only to the phonetic context is incomplete. Specifically, the paper argues that pragmatic inferences that typically appear cross-linguistically associated with these connectors, and that result in asymmetric interpretations, are not favoured in Spanish with the morphological variants e and u, which favour symmetric interpretations. The paper proposes that the relevant pragmatic inferences have been partially conventionalized for y and o, but that this conventionalization has not occurred in the case of e and u for the reason that they are much less frequently used. Thus, discussion and data offer a view of a stage in a gradual process of semantic change via conventionalization of pragmatic inferences.
