This book constitutes an exhaustive study of linguistic structures in Paraguayan Guaraní which are directly or indirectly associated with the semantic domain of inalienability. Constructions analyzed in the book include adnominal and predicative possessive constructions, noun incorporation, and possessor ascension. Examples are drawn from a rich data base that incorporate native speaker intuitions and resources in the construction of illustrative linguistic forms as well as the analysis of the communicative use of the forms under study. The book provides a complete picture of inalienability as a coherent integrated system of grammatical and semantic oppositions in a language that has received little attention in the theoretical linguistic literature. The analysis moves from general principles to specific details of the language while applying principles of Cognitive Grammar and Functional Linguistics. There is an explicit aim to uncover the particularities of form-meaning connections, as well as the communicative and discourse functions of the structures examined. Other approaches are also considered when appropriate, resulting in a theoretically informed study that contains a rich variety of considerations.
