This book investigates how semivowels were realized in Indo-European and in early Greek. More specifically, it examines the extent to which Indo-European *i and *y were independent phonemes, in what respects their alternation was predictable, and how this situation changed as Indo-European developed into Greek. The comprehensive and chronologically sensitive nature of this study, together with its careful assessment of what is inherited and what is innovative, enables substantive conclusions to be drawn regarding the behaviour of semivowels at various stages in the history of Greek and in Indo-European itself.

This book reconciles what is known of the Proto-Indo-European verbal system with the evidence of Hittite and the other early Anatolian languages. The decipherment of Hittite in 1917 and the recognition that it was an Indo-European language had dramatic consequences for conceptions of the Indo-European parent language. For most of the twentieth century, the 'disconnects' between Hittite and the other early languages such as Sanskrit and Greek have been the subject of research,scholars finally realizing that the question was not whether the conventional picture of the parent language should be modified to account for the facts of Hittite, but how. After investigating the subject for twenty-five years, Professor Jasanoff proposes a resolution of the problem that is the mostthorough and systematic yet published. In this outstanding book he puts forward a new and revolutionary model of the Proto-Indo-European verbal system which will have a profound impact on the study of the Indo-European family of languages. It also represents a significant advance in the understanding of the history of Indo-European.
