Occitan, also known as Provençal, is a Romance language spoken in southern France, northern Italy, and parts of Spain. The term "Occitan" is often used interchangeably with "Langue d'Oc," which means "language of Oc," a reference to the word for "yes" in the dialect.
Some alternative synonyms for "Occitan" include "Provençal," referring specifically to the dialect spoken in Provence; "Languedoc," referring to the region where the language is spoken; and "Gascon," which is a separate dialect spoken in the Gascony region of southwestern France.
Other synonyms include "Occitano," the Italian word for Occitan; "Oc," used by some Occitan speakers as a shorthand for the language; and "Occitania," a term used to refer to the larger historical and cultural region where Occitan is spoken.
