On the Categorial Status of Adverbs

This paper is concerned with the question of what adverbs in English are as a category. It argues that English adverbs are not positional variants of a single category together with adjectives but also do not constitute a separate lexical category on their own, as is commonly assumed. Instead, this paper advocates the position that adverbs can and should be assimilated with PPs and offers a comprehensive presentation of this view. In particular, it provides evidence that the morpheme -ly is not a suffix but a nominal root, which forms the basis of the analysis of adverbs as PPs. Furthermore, it shows that the PP analysis of adverbs is able to account for a variety of facts, including those that have been previously used as arguments for alternative analyses. Finally, this paper demonstrates that the PP analysis allows for a straightforward compositional semantics, using manner and degree adverbs as case studies, and provides an outlook into the cross-linguistic situation in the domain of adverbs from the perspective of their morphological structure.
