In fact the Hausas don't pronounce the word Yamiri but they say Nyamiri.

Wrong ·Yamiri· was not created during the Biafra war although it is a mockery name from the Hausa to the Igbos it has always existed decades before that war. In fact that definition is at the limit of an insult to any Igbo called so but certainly a lack of respect to be called Yamiri.
