Semitic languages
Arabic languages and dialects are currently the native languages of majorities from Mauritania to Oman, and from Iraq to the Sudan. Classical Arabic is the language of the Quran. It is also studied widely in the non-Arabic-speaking Muslim world. The Maltese language is genetically a descendant of the extinct Siculo-Arabic, a variety of Maghrebi Arabic formerly spoken in Sicily. The modern Maltese alphabet is based on the Latin script with the addition of some letters with diacritic marks and digraphs. Maltese is the only Semitic official language within the European Union.
