Igboid languages constitute a branch of the Volta–Niger language family. It includes Ekpeye, Ukwuani, and the Igbo languages:
|South central Nigeria, lower reaches of the Niger River and east, south the Benue|
Williamson and Blench conclude that the Igbo languages (Igboid apart from Ekpeye) form a "language cluster" and that they are somewhat mutually intelligible. However, mutual intelligibility is only marginal, even among the Izii–Ikwo–Ezaa–Mgbo languages.
