Langues d'oïl
From Textus Receptus
The langues d'oïl (/ˈwiːl/ French: [lɑ̃ɡᵊdɔjl]), or oïl languages (also in French: langues d'oui [lɑ̃ɡᵊdwi]), are a dialect continuum that includes standard French and its closest autochthonous relatives spoken today in the northern half of France, southern Belgium, and the Channel Islands. They belong to the larger Gallo-Romance languages, which also cover most of east-central (Arpitania) and southern France (Occitania), northern Italy and eastern Spain (Catalan Countries).
Linguists divide the Romance languages of France, and especially of Medieval France, into three geographical subgroups: Langues d'oïl and occitan, named after their words for 'yes' (oïl, òc), and Franco-Provençal (Arpitan), which is considered transitional.
