Occitan took a different path from Latin to the main official languages. It is sometimes called lenga d'òc ("language of oc", French: langue d'oc) because its word for yes is òc, as opposed to oil (oui) or sì in other languages. That is one way to classify Romance languages.
Occitan is an official language of Catalonia.[9] Since September 2010, the Parliament of Catalonia has considered Aranese Occitan to be the officially preferred language for use in the Val d'Aran.
Dialects
Alpine (also named Vivaro-Alpine or Provençal Alpine)
Some of those names (Provençal, Limousin, Gascon) were once used for the whole language.
