This is a study of Russian nominalizing evaluative suffixes that form nouns of the -adeclension. Such suffixes are interesting because they can consistently change the animacy, declension class, and grammatical gender of the base to which they attach. However, the resulting nominalizations belong to different grammatical genders that seem to depend on the biological gender of a discourse referent.This work investigates morphosyntactic properties of such evaluative suffixes and proposes an account for the differences in grammatical gender in the framework of Distributed Morphology (Halle and Marantz 1993, Halle 1997, Marantz 1997, among many others), which provides us with formal tools for handling syntactic processes that happen inside a word -in this case, inside evaluative nominalizations.The study contributes to a number of much-debated questions in the current linguistic literature concerning the interaction between grammatical gender and declension class, mixed gender agreement, interpretability of gender features, and default gender.
