Koro Nulu, also known as Koro Ija, is a Plateau language of Nigeria, one of several languages which go by the ethnic name Koro. It is not closely related to other languages. It has very low (~ 7%) lexical similarity with Koro Zuba, which speakers consider to be a variant of the same language (along with the Jilic languages) due to ethnic identity. ^[2] However, the Jilic languages are Plateau and Koro Zuba is apparently Nupoid, and Koro Nulu has yet to be classified.
