The Gallo-Romance family is a subgrouping of the Romance languages. Its most prominent member is French. Another member of the group is Arpitan (sometimes known as Franco-Provençal, as it was seen as midway between French and the Occitan dialect Provençal), which was historically spoken widely in eastern France (and Franco Switzerland) but is now largely restricted to the Aosta Valley in Italy. The Gallo-Romance group as a whole was once known as the langues d’oïl (as opposed to the langues d’òc, namely Occitan, to their south). This group is one of the most innovative among all the Romance subdivisions, with extensive phonological and grammatical changes, the latter of which has seemed to be the result of heavy Germanic influences.
