Aragonese language
The Aragonese language has many local varieties, which are grouped in valley varieties or "comarca" varieties. The term "dialect" is ambiguous and it can be used to refer to well-known valley varieties, such as "cheso" or "ansotano". The best-known classification, by Francho Nagore, divides all Aragonese varieties in four groups or main dialects: Western, Central, Southern, and Eastern.
