France [SEP] Etymology and pronunciation
Originally applied to the whole Frankish Empire, the name "France" comes from the Latin , or "realm of the Franks". Modern France is still named today in Italian and Spanish, while in German, in Dutch and in Swedish all mean "Land/realm of the Franks". There are various theories as to the origin of the name Frank. Following the precedents of Edward Gibbon and Jacob Grimm, the name of the Franks has been linked with the word "frank" ("free") in English. It has been suggested that the meaning of "free" was adopted because, after the conquest of Gaul, only Franks were free of taxation.
