A Brief History of Igbo People, Culture And Language

Before we begin our lessons, I like to make a brief introduction of the language which we are about to learn. Igbo is spoken by over 25 million people who are primarily of Igbo descent. In southeastern Nigeria and parts of Niger-Delta, Igbo is spoken natively. It is written in the Latin Alphabet, as introduced by British Colonist. Other scripts include the Ekpe Nsibidi ideograms.

Igbo dialect continuum, distinguished by accent and orthography but almost universally mutually intelligible, including the Idemili dialect of Chinua Achebe's novel, The Things Fall Apart others are Umuahia, Onitsha, Enuani (which includes Ika, Ukwuani, Anioma), Ngwa, Akwa, Mbaise, Nsukka, Orlu, Afikpo, Nsa, Oguta, Ikwerre, Etche, Egbema, Owerri, Bonny-Opobo, Ohuhu, Unwana. There is apparently a degree of dialect leveling occurring. A standard literary language was developed in 1972; this is based on Owerri and Umuahia, though it omits the nasalization and aspiration of those varieties. There are related Igbo Languages as well that are sometimes considered dialects of Igbo, the most divergent being Ekpeye. Some of these, such as Ika, have separate standard forms. Igbo Language is also the spoken language of some parts of Africa like Niger-Congo, Cameroon, and Equatorial Guinea.
