THE COORDINATION OF UNLIKE CATEGORIES

I argue that the account of the coordination of unlike categories, suc h as wealthy and a Republican in become wealthy and a Republican, ough t to be unified with the account of feature neutralization under phono logical identity, in which (for instance) coordinations of dative- and accusative-taking transitive verbs are possible just when the object is ambiguous (or underspecified) between dative and accusative case. I argue that this unified account ought not to be couched in terms of s trings (as in Chametzky 1987) or features (as in Sag et al. 1985) but rather in terms of the logic of categories, in the tradition of Lambek Categorial Grammar. I present and defend such an account.
