Ibibio (proper) is the native language of the Ibibio people of Akwa Ibom State, Nigeria, belonging to the Ibibio-Efik dialect cluster of the Cross River languages. The name Ibibio is sometimes used for the entire dialect cluster. In pre-colonial times, it was written with Nsibidi ideograms, similar to Igbo, Efik, Anaang, and Ejagham. Ibibio has also had influences on Afro-American diasporic languages such as AAVE words like buckra, which comes from the Ibibio word mbakara, and in the Afro-Cuban tradition of abakua.
Between consonants, /i, u, o/ have allophones that are transcribed [?, ?, ?], respectively. At least in case of [?, ?], the realization is probably somewhat different (e.g. close-mid [e, ?]), because the default IPA values of the symbols [?, ?] are very similar to the normal realizations of the Ibibio vowels /i, ?/. Similarly, [?] may actually be near-close , rather than close .
In some dialects (e.g. Ibiono), /?, ?, ?/ occur as phonemes distinct from /i, u, o/.
Ibibio has two tones: high and low. A word can be used to mean two or more different things based on the tone ascribed to it.
