Ibibio language

In pre-colonial times, it was written with Nsibidi ideograms, similar to Igbo, Efik, Anaang, and Ejagham.

Ibibio communities in Opobo Nkoro and Oyigbo LGA's of Rivers State are largely unknown.

Some Ibibios are also found in other neighboring countries (western Cameroon, Bioko — central Guinea, and Ghana).

Intervocalic plosives are lenited:[2] Between consonants, /i, u, o/ have allophones that are transcribed [ɪ, ʉ, ə], respectively.

[2] Ibibio has five phonemic tones: high, mid, rising, falling and low.
