Not since 1937 has a classic reference work appeared for Indo-European. This new work, however, steps forth to fill a major gap in this rapidly changing field by making full use of the recent achievements in linguistic theory. Useful as both an introductory survey and a reference for advanced students and scholars, the volume provides insight into the variations in the way Indo-European is studied while at the same time presenting a unified overview of Indo-European. The first three chapters provide an important introduction, while the remaining sixteen chapters are dedicated to a subgroup of the Indo-European language family and cover phonology, morphology, syntax and lexicon of each family.
