(Un)interpretable Neg in Comp

This article explores the possibility that the distinction between interpretable (valued) and uninterpretable (unvalued) features has grammatical manifestations beyond its role in feature checking. Iargue that both selection and lexical insertion are sensitive to this distinction; thus, a head may determine not only which features its complement must bear but also whether they should be interpretable or not. Empirical consequences are explored in Hebrew, where infinitival complements to negative verbs ( refrain , prevent ) display a number of surprising syntax-semantics correlations. Those are traced to the operation of negative features in the Comp position. The analysis also provides insight into the recalcitrant prevent DP from V-ing construction in English.
