Igbo, or Igbo proper, is a native language of the Igbo people, an ethnic group primarily located in southeastern Nigeria. There are approximately 20 million speakers that are mostly in Nigeria and are primarily of Igbo descent. Igbo is the language of Ibo people of Eastern Nigeria. It is written in the Latin script, which was introduced by British colonialists. There are over 20 Igbo dialects. There is apparently a degree of dialect leveling occurring. A standard literary language was developed in 1972 based on the Owerri and Umuahia dialects, though it omits the nasalization and aspiration of those varieties. There are related Igboid 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. Wikipedia
