Maltese (Maltese: Malti) is the national language of Malta and a co-official language of the country alongside English, while also serving as an official language of theEuropean Union, the only Semitic language so distinguished. Maltese is descended from Siculo-Arabic, the variety of Arabic that developed in Sicily and was later introduced to Malta, between the end of the ninth century and the end of the twelfth century. Maltese is a unique branch of Arabic because it has evolved independently of Literary Arabic into a standardized language over the past 800 years in a gradual process of Latinisation.
