Oc

   the language traditionally spoken in the south of France, notably in the Languedoc (meaning Language of Oc region). Occitanian languages, the family of Oc languages (for it is more than just a single tongue), were historically spoken in "Occitania"(see below) from the Atlantic to the southern Alps, from parts of Spain to the Val d'Aosta in Italy. Oc languages include Provençal. Linguistically they are close to Catalan, the traditional language of Catalonia in Spain and the Pyrénées Orientales department of France.
