#30321: A side note: I understood that Somali is preferred over Somalian

Posted by: Anna_X at 7:59 am on Jun 3, 2018

One person is Somali, plural persons are Somalis, the language is Somali, and the country is Somalia. My students rolled their eyes over being called Somalian. That seems to have been created by Westerners who use English rules for nationalities from countries ending with a or ia.
On the other hand, some did adopt the term Somalian to avoid correcting well-meaning Americans.
I apologize if I am preaching instead of explaining.
