Most widely used language on the Comoros (independent islands in the Indian Ocean, off Moçambique and Madagascar).
Shikomor is a blend of Swahili and Arabic and one of the three official languages on the Comoros, next to French and Arabic.
It is also the language of "Umodja wa massiwa", the national hymn of the moon islands ("al-qamar" is Arabic for "moon").
