(Non-)Intersective adjectives and root suppletion

In this paper I examine certain gradable adjectives in Serbian, whose suppletive comparative forms display unexpected semantic properties. In particular, while these adjectives are ambiguous between intersective and non-intersective readings in the positive form, their suppletive comparative and superlative forms are limited to the non-intersective interpretation. These facts show, I argue, that in a theory like Distributed Morphology either adjectival roots or category-assigning heads they combine with come in semantic subtypes (i.e. are specified for certain semantic properties; Harley 2005, Anagnostopoulou and Samioti 2014). I show how the analysis I propose explains semantic properties of change-of-state verbs derived from these adjectives and why these adjectives are restricted to the intersective interpretation when their positive form takes the long-form (definite) inflection. I also provide an illustration of how Arregi and Nevins's (2014) analysis of the so-called "disuppletive" roots, such worse/badder, can deal with the facts presented in this paper. Finally, I discuss implications of these facts in the context of Bobaljik's (2012) approach to suppletive comparative morphology.
