Nigeria is actually a big country, The Hausa ethnic group; other division may actually look like the hausa group but its definitely not e.g Fulani, there is another in one of its state "Benue", we have TiV in the central belt, we have agun are in the west that sub-division of yoruba, their language there is so strange🤣, i am from the south in my state the are 3 different ethnic group of which i know i cannot understand their language, so don't be surprise when i said 250. By the way i appreciate your engagement on my post, Thanks a lot.
