Resumen de Imperfectivization in Russian

Irina Mikaelian, Alexei Shmelev, Anna Zalizniak

• Imperfectivization can be understood in two different ways that should be thoroughly distinguished. The first corresponds to morphological imperfectivization, i.e. the derivation of an imperfective verb from a perfective one by the addition of a suffix. The second meaning of the discussed term corresponds to "obligatory imperfectivization", i.e. a more general functional mechanism that forces the speaker to replace any perfective verb with an imperfective partner in contexts where perfective verbs are not allowed. The notions of aspectual correlation as opposed to that of aspectual partnership are discussed; a functional analysis of "aspectual trios" is proposed.
