The langues d'oïl are a dialect continuum of Romance languages that include standard French and its closest relatives historically spoken in the northern half of France, southern Belgium, and the Channel Islands.

The term langue d’oïl is based on the French use of the word oïl, modern oui, for “yes”). Standard French has also greatly reduced the use of the Occitan language of southern France (the so-called langue d’oc, from Provençal oc for “yes”).
