Mozarabic language

Mozarabic is an extinct Romance language formerly spoken in the Muslim territories of the Iberian Peninsula during the Middle Ages. It remains poorly documented, mainly in place names and in some words mentioned in medieval documents which were redacted in other languages. It might have been sometimes written in Arabic alphabet but this is not accepted by all scholars. Mozarabic was more and more weakened by the domination of Arabic and, because of the Reconquista, it was progressively replaced or absorbed by the advance of other Romance languages coming form the northern, Christian zones of the peninsula (Portuguese, Asturian-Leonese, Spanish, Aragonese and Catalan). The language disappeared rapidly after the 15th century. Some authors think that it had already died out in the second half of the 12th century, being completely replaced by Arabic, before the arrival of northern Romance languages.
