Aýna[1] (pronounced as /es/) is a small village and municipality in the southern region of the province of Albacete, in the Spanish autonomous community of Castile-La Mancha. It is a popular summer vacation destination due to its pleasant scenery and climate. It has a population of over 900 inhabitants, which has declined between 1950 and 2000. Aýna is referred to as "Manchegan Switzerland" due to its location between two mountain ranges.
The name of Aýna is derived from the Arabic meaning or .[1] The spelling of the town preserves an archaic use of the letter (y), which was common in Old Castilian. Although the historic spelling used the letter (y),[1] the modern spelling contains an accent to indicate the (a) and (ý) belong to different syllables rather than forming a diphthong.[1] [2] The spelling is notable for having one of the only Spanish language use of the character (ý).[1]
