The typological studies of this volume are oriented towards the areas of interests of the Russian typologist Vladimir P. Nedjalkov, to whom the volume is dedicated. They deal with the typology of verbal categories. The book is divided into three parts: 1. "e;Ergativity and transitivity"e;, 2. "e;Voice, causative and valency"e;, 3. "e;Tense and mood"e;. In all three parts of the volume instances of grammaticalization are pointed out and investigated. The studies concern various languages, e.g. English, French, German, Russian, Hungarian, Dutch, Tariana (a North Arawak language from North West Amazonia), Dumi (a Tibeto-Burman language), and Lak (a Daghestanian language).
