Ribagorçan (ribagorzano, ribagorsano) is a transitional Aragonese and Catalan dialect spoken in the area of Aragon and Catalan Ribagorçan (ribagorçà) is a Catalan dialect spoken in the Alta Ribagorça, Catalonia. Speakers of Pont de Suert use a Catalan variant transitional to Aragonese with some traits of AraneseOccitan. However, Aragonese and Catalan form a dialectal continuum in the region and it is not possible to draw the geographical limit of both languages in a clear-cut manner.[9]
