Siwans are members of a unique ethnic group inhabiting the remote oasis of Siwa, located in the Egyptian Western Desert near the Libyan border. They speak the unwritten Siwi, a language derived from Amazigh/Berber. Along with the Nubian and Coptic languages, the use of Siwi has been in decline. It is being replaced by the Egyptian dialect of Arabic as the main form of verbal communication in the region.
