The Caucasus is the place with the greatest linguistic variation in Europe. The present volume explores this variation within the tense, aspect, mood, and evidentiality systems in the languages of the North-East Caucasian (or Nakh-Daghestanian) family. The papers of the volume cover the most challenging and typologically interesting features such as aspect and the complicated interaction of aspectual oppositions expressed by stem allomorphy and inflectional paradigms, grammaticalized evidentiality and mirativity, and the semantics of rare verbal categories such as the deliberative (‘May I go?’), the noncurative (‘Let him go, I don’t care’), different types of habituals (gnomic, qualitative, non-generic), and perfective tenses (aorist, perfect, resultative). The book offers an overview of these features in order to gain a broader picture of the verbal semantics covering the whole North-East Caucasian family. At the same time it provides in-depth studies of the most fascinating phenomena.
