This book is the first complete theory of the morphology of language. It describes both inflection and lexical word formation, their relation to syntax, phonology, and semantics, and to each other. It enumerates most of the morphological categories of the world's languages, describing their recombinant abilities, and how they are realized in inflectional and lexical derivations.

Robert Beard is the Director of the Linguistics Program at Bucknell University.
