This book explores the wealth of evidence from early Indo-Aryan for the existence of transitive nouns and adjectives, a rare linguistic phenomenon which, according to some categorizations of word classes, should not occur. John Lowe shows that most transitive nouns and adjectives attested in early Indo-Aryan cannot be analysed as a type of non-finite verb category, but must be acknowledged as a distinct constructional type. The volume provides a detailed introduction to transitivity (verbal and adpositional), the categories of agent and action noun, and to early Indo-Aryan.
