Sommario/riassunto

A comprehensive review of current thinking on the biosynthesis, function and evolution of secondary metabolites in animals, plants and microorganisms. Examines the traditional context of secondary metabolites as natural products having no obvious part to play in the producing organism's life cycle. Covers issues related to genetic and antibiotic applications.

Nota di contenuto

pt. 1. Morphosyntax -- pt. 2. Semantics -- pt. 3. Phonology -- pt. 4. Language contact.

Sommario/riassunto

The 16 papers in this volume are revised versions of papers presented



at the conference; they represent the state of the art in various subfields of African linguistics into which the book is organized: (1) morphosyntax, (2) semantics, (3) phonology, and (4) language contact. The last part covers topics such as code-switching and mixing, pidginization/creolization, and language planning. The papers in Part I: Morphosyntax focus particularly on the verb and verb phrase in a variety of Niger-Congo languages, discussing several aspects of the verb morphology.
