Concept
French is a Romance language (meaning that it is descended primarily from Vulgar Latin) that specifically is classified under the Gallo-Romance languages. The discussion of the history of a language is typically divided into "external history", describing the ethnic, political, social, technological, and other changes that affected the languages, and "internal history", describing the phonological and grammatical changes undergone by the language itself. Before the Roman conquest of what is now France by Julius Caesar (58–52 BC), much of present France was inhabited by Celtic-speaking people referred to by the Romans as Gauls and Belgae. Southern France was also home to a number of other remnant linguistic and ethnic groups including Iberians along the eastern part of the Pyrenees and western Mediterranean coast, the remnant Ligures on the eastern Mediterranean coast and in the alpine areas, Greek colonials in places such as Marseille and Antibes, and Vascones and Aquitani (Proto-Basques) in much of the southwest. The Gaulish-speaking population is held to have continued speaking Gaulish even as considerable Romanisation of the local material culture occurred, with Gaulish and Latin coexisting for centuries under Roman rule and the last attestation of Gaulish to be deemed credible having been written in the second half of the 6th century about the destruction of a pagan shrine in Auvergne. The Celtic population of Gaul had spoken Gaulish, which is moderately well attested and appears to have wide dialectal variation including one distinctive variety, Lepontic. The French language evolved from Vulgar Latin (a Latinised popular Italic dialect called sermo vulgaris), but it was influenced by Gaulish. Examples include sandhi phenomena (liaison, resyllabification, lenition), the loss of unstressed syllables and the vowel system (such as raising /u/, /o/ → /y/, /u/, fronting stressed /a/ → /e/, /ɔ/ → /ø/ or /œ/). Syntactic oddities attributable to Gaulish include the intensive prefix ro- ~ re- (cited in the Vienna glossary, 5th century) (cf.
