Offers a view of the evolution of Trubetzkoy's ideas on phonology, the logic in laws of linguistic geography and relative chronology, and the breadth of his involvement with Caucasian phonology and the Finno-Ugric languages. This volume sheds light on problems that remain at the center of contemporary linguistics.

"This collection of Trubetzkoy's articles and letters from widely scattered sources is an important and welcome contribution to both the history of linguistics and the advancement of current knowledge."--Victor Friedman, University of Chicago
