Welsh toponymy

Welsh toponymy is the study of the place-names of Wales, most of which are derived from the Welsh language, though others reflect linguistic contact with the Romans, Anglo-Saxons, Vikings, Anglo-Normans and modern English. Toponymy in Wales reveals significant features of the country's history and geography, as well as the development of the Welsh language. Its study is promoted by the Welsh Place-Name Society (Cymdeithas Enwau Lleoedd Cymru).
