Occitan (English pronunciation: /ˈɒksᵻtən, -tæn, -tɑːn/; Occitan: [utsiˈta]; French: [ɔksitɑ̃]), also known as lenga d'òc (Occitan: [ˈleŋɡɔ ˈðɔ(k)]; French:langue d'oc) by its native speakers, is a Romance language. It is spoken in southern France, Italy's Occitan Valleys, Monaco, and Spain's Val d'Aran; collectively, these regions are sometimes referred to unofficially as Occitania. Occitan is also spoken in the linguistic enclave of Guardia Piemontese (Calabria, Italy). However, there is controversy about the unity of the language, as some think that Occitan is a macrolanguage. Others include Catalan in this family, as the distance between this language and some Occitan dialects (as the Gascon language) is similar to the distance among different Occitan dialects. In fact, Catalan was considered an Occitan dialect until the end of the 19th century.
