In page Occitan language:

"

Many Occitan linguists and writers,[3] particularly those involved with the pan-Occitan movement centered on the Institut d'Estudis Occitans, disagree with the view that Occitan is a family of languages; instead they believe Limousin, Auvergnat, Languedocien, Gascon, Provençal and Vivaro-Alpine are dialects of a single language. Although there are indeed noticeable differences between these varieties, there is a very high degree of mutual intelligibility between them[4] partly because they share a common literary history; furthermore, academic and literary circles have identified them as a collective linguistic entity—the lenga d'òc—for centuries.[citation needed]
