Old French was the language spoken in most of the northern half of France approximately between the late 8th and mid-14th centuries. Rather than a unified language, Old French was a group of Romance dialects, mutually intelligible yet diverse. These dialects came to be collectively known as the langues d'oïl, contrasting with the langues d'oc, the emerging Occitano-Romance languages of Occitania, now Southern France.
