|ISO 639-2 / 5||ijo|
The Ijo languages are traditionally considered a distinct branch of the Niger–Congo family (perhaps along with Defaka in a group called Ijoid). They are notable for their subject–object–verb basic word order, which is otherwise an unusual feature in Niger–Congo, shared only by such distant potential branches as Mande and Dogon. Like Mande and Dogon, Ijoid lacks even traces of the noun class system considered characteristic of Niger–Congo. This motivated Joseph Greenberg, in his initial classification of Niger–Congo, to describe them as having split early from that family. However, owing to the lack of these features, Linguist Gerrit Dimmendaal doubts their inclusion in Niger–Congo altogether and considers the Ijoid languages to be an independent family.
The following internal classification is based on Jenewari (1989) and Williamson & Blench (2000).
- West (or Central)
