Despite superficial similarity, the English term "Gaul" is unrelated to the Latin "Gallia". It stems from the French "Gaule", itself deriving from the Old Frankish "*Walholant" (via a Latinized form "*Walula"), literally the "Land of the Foreigners/Romans". "*Walho-" is a reflex of the Proto-Germanic "*walhaz", "foreigner, Romanized person", an exonym applied by Germanic speakers to Celts and Latin-speaking people indiscriminately. It is cognate with the names Wales, Cornwall, Wallonia, and Wallachia. The Germanic "w-" is regularly rendered as "gu-" / "g-" in French (cf. "guerre" "war", "garder" "ward", "Guillaume" "William"), and the historic diphthong "au" is the regular outcome of "al" before a following consonant (cf. "cheval" ~ "chevaux"). French "Gaule" or "Gaulle" cannot be derived from Latin "Gallia", since "g" would become "j" before "a" (cf. "gamba" > "jambe"), and the diphthong "au" would be unexplained; the regular outcome of Latin "Gallia" is "Jaille" in French, which is found in several western place names, such as, La Jaille-Yvon and Saint-Mars-la-Jaille. Proto-Germanic "*walha" is derived ultimately from the name of the Volcae.
