Central Ibibio is the major dialect cluster of the Cross River branch of Benue–Congo. Efik proper has national status in Nigeria and was erroneously made the literary standard of the Ibibio language, though Ibibio proper has more native speakers.
Efik-Ibibio is a dialect cluster spoken by about 15 million people of Akwa Ibom State and about 5 million people of Cross River States of Nigeria, making it the fifth largest language cluster in Nigeria after Hausa, Yoruba, Igbo and Fulani.
