# Old Leonese language

Old Leonese or Medieval Leonese is a West Iberian dialect of Vulgar Latin spoken in several regions of the Kingdom of León and the medieval Principality of Asturias. It was the ancestor of several languages, all forming the Asturleonese language family. Old Leonese was spoken until around the year 1500, and was attested starting from the 10th century with the Nodicia de kesos.

## Phonology
### Consonants

* The sound change to in some contexts may appear in Old East and Central Leonese (such as in muyer and meyor). According to some researchers, this trait might have contributed to the spread of yeísmo in Castilian, brought by Asturian and Leonese settlers.

### Vowels

* Latin ŏ and ĕ developed in Old Leonese to /we/ and /je/ respectively, such as in puerta. Compare Old Galician-Portuguese porta. However, in areas of Galician-Portuguese influence, monophthongisation may occur, more often in /we/ reverting to /ɔ/. Some texts shown both forms though (bono & bueno, corpo & cuerpo, etc.).

## Literature

The first text in the Leonese vernacular was the Nodicia de kesos, dated from the 10th century. Meanwhile, in 1155, Fueru d'Aviles was written, being the oldest text in the Asturian vernacular. The majority of Old Leonese texts from the 13th century are in the book Étude sur l'ancien dialecte léonais d'après des chartes du XIIIe siècle by Erik Staaff in 1907. A notable text is the translation of liber iudiciorum, the Fuero juzgo or Fueru xulgu.
