Gallo-Romance languages
Today, a single Gallo-Romance language (French) dominates much of the geographic region (including the formerly-non-Romance areas of France) and has also spread overseas.At its broadest, the area also encompasses Southern France; Catalonia, the Valencian Community, and the Balearic islands in eastern Spain; Andorra; and much of Northern Italy.Characteristic Gallo-Romance features generally developed the earliest, appear in their most extreme manifestation in the langue d'oïl and gradually spread out from there along riverways and roads.Franco-Provençal, however, generally preserves the original final vowel after a syllable-final cluster, such as quattuor "four" > quatro (compare French quatre).For example, French sain, saint, sein, ceint, seing meaning "healthy, holy, breast, (he) girds, signature" (Latin sānum, sanctum, sinum, cingit, signum) are all pronounced /sɛ̃/.
