Lake Geneva the lake is "Lacus Lemannus", dating from Roman times; "Lemannus" comes from Ancient Greek "Limenos Limne" (Λιμένος Λίμνη) meaning "port's lake"; it became "Lacus Lausonius", although this name was also used for a town or district on the lake, "Lacus Losanetes", and then the "Lac de Lausanne" in the Middle Ages. Following the rise of Geneva it became "Lac de Genève" (translated into English as "Lake Geneva"). In the 18th century, "Lac Léman" was revived in French and is the customary name in that language. In contemporary English, the name "Lake Geneva" is predominant. A note on pronunciation: Lake Geneva
