Infinitive im R̥gveda is an in-depth study of infinitives in Early Vedic, the language of the R̥gveda. Infinitives in Vedic have been studied from various perspectives. This book, however, is the first to give a detailed account of the full range of the attested morphological, syntactic, and semantic types. Based on insights from formal semantics and syntactic theory, the author gives explicit analyses for each type, paying special attention to the grammatical functions involved and to the control relations which govern the reference of subjects in infinitive phrases. On a more general level, the book provides a framework for historical syntax and heuristics for studying syntactic categories in ancient languages.
