Recherches sur les langues celtiques

William Frédéric Edwards' Recherches sur les langues celtiques, first published in 1844, represents a foundational examination of Celtic linguistics during a critical period of scholarly development. This work undertakes a detailed lexicographical and grammatical analysis to delineate the distinct characteristics of Celtic idioms as they were spoken in France and the British Isles.

Edwards investigates the nature and extent of linguistic borrowings these Celtic languages acquired from Latin and other tongues. The research contributes to understanding the historical evolution and unique structure of Celtic languages, offering insights into early comparative linguistic methods and the intellectual currents that shaped the study of these languages in the 18th and early 19th centuries.
