Comorian (Shikomor) is the most widely used language on the Comoros (independent islands in the Indian Ocean, off Mozambique and Madagascar). It is a close relative of Swahili with a very strong Arabic influence. Each island has a slightly different dialect; that of Anjouan is called Shindzuani, that of Mohéli Shimwali, that of Mahoré Shimaore, and that of Grande Comore Shingazidja. No official alphabet existed in 1992, but Arabic and Latin scripts were both used.
Shimasiwa is another name for Comorian, but while Shikomoro means "Comorian language", the meaning of Shimasiwa is "language of islands".
It is also the language of Udzima wa ya Masiwa, the national anthem of the "moon islands" ("al-qamar" is Arabic for "moon").
