It has a southern coastline on the Gulf of Guinea, and has Benin to the west, Cameroon to the southeast, Chad to the northeast, and Niger to the north. Its capital is Abuja.

However, the national lingua franca is Nigerian pidgin, an English-based creole language spoken by a whooping 75 million people as a second language and by 3-5 million people as a native language, mostly in the Niger Delta.
