The volume contains 37 papers originally presented at the 8th International Conference on Historical Linguistics in Lille, France. The papers bring historical data to bear on issues in theoretical linguistics, both descriptive and diachronic or deal with specific questions in the history of individual languages. The theoretical issues range from phonology over morphology and syntax to the lexicon, as well as questions of historical dialectology, language contact, the theory of linguistic change, and problems of comparative reconstruction. The languages discussed are Finno-Ugric and Indo-European, most of the papers dealing with Germanic and Romance languages (especially English and French), but some being devoted to Greek, Celtic, Slavic, and Hittite.
