Classification
The classification of Ikwerre as an Igbo dialect is a subject of controversy among some in the Ikwerre community. Most publications classify it as an Igboid language. Based on lexicostatistical analysis, Kay Williamson originally asserted that the Ikwerre, Ekpeye, Ogba, Etche and Igbo languages belonged to the same language cluster, but were not dialects. Subsequent studies by both Williamson and Roger Blench concluded that Igbo, Ikwerre, Ogba and their sister languages apart from Ekpeye form a "language cluster" and that they are somewhat mutually intelligible. There are indications that the Ikwerre society was bilingual even in the pre-colonial Nigeria, with people speaking other Igbo dialects and Ikwerre.
