Since its publication in 1969, Émile Benveniste’s Vocabulaire—here in a new translation as the Dictionary of Indo-European Concepts and Society—has been the classic reference for tracing the institutional and conceptual genealogy of the sociocultural worlds of gifts, contracts, sacrifice, hospitality, authority, freedom, ancient economy, and kinship. A comprehensive and comparative history of words with analyses of their underlying neglected genealogies and structures of signification—and this via a masterful journey through Germanic, Romance, Indo-Iranian, Latin, and Greek languages—Benveniste’s dictionary is a must-read for anthropologists, linguists, literary theorists, classicists, and philosophers alike.
