Lopa language

Lopa consists of a pair of minor Kainji languages of Nigeria. The Lopa people neighbouring the Busa [language (Mande)|Busa language] have shifted to that language.
The two languages are Rop and Urcibar. Additionally, there is a native name for both dialects as a whole: Rerang, which is unusual in West Kainji languages.
Blench lists Tsupamini as a related variety.
McGill also gives the alternate name Oleran for Lopa.
