This book provides some of the fruits of a career teaching Slavic linguistics and phonological theory. Bill Darden was trained in both Prague-School linguistics and generative phonology, and integrates both in his work. He was among the early proponents of the relevance of phonemics and the distinction between morphophonology and phonology in generative phonology. He uses his knowledge of Slavic history to marshal theoretical arguments in phonology, and uses phonological theory to help explain phenomena in the history of Russian. In pure historical linguistics, he offers possible solutions for one of the biggest problems in Balto-Slavic historical linguistics—the reconstruction of the Balto-Slavic verb and the sources of that system in Indo-European.
