イボ語
There are some discussions as to whether the Igbo language is in danger of extinction, advanced in part by a 2006 UNESCO report that predicted the Igbo language will become extinct within 50 years. Professor of African and African Diaspora Literatures at University of Massachusetts, Chukwuma Azuonye, emphasizes indicators for the endangerment of the Igbo language based on criteria that includes the declining population of monolingual elderly speakers; reduced competence and performance among Igbo speakers, especially children; the deterioration of idioms, proverbs, and other rhetorical elements of the Igbo language that convey the cultural aesthetic; and code-switching, code-mixing, and language shift.
