The two languages are Rop (Ollop) and Urcibar (Shuba). Additionally, there is a native name for both dialects as a whole: Rerang, which is unusual in West Kainji languages.[2]
Blench (2019) lists Tsupamini as a related variety.[3]
McGill (2012) also gives the alternate name Oleran for Lopa.[4]
Dialects
The name Lopa likely comes from the name lópár (Lapar), which refers to both the Rop and the Shuba. Cover terms referring to both Urcibar and Ollop speakers are [dɔ̀ɾìɾáŋ̃ ] (one person), [òːɾìɾáŋ̃ ] (many people), and the language [òlːèɾáŋ̃].[2]
Urcibar (Shuba) is spoken in the major villages of ò̃tʃébá (Cifamini), tʷò̃tʃíɡí (Gungun Tagwaye), ò̃sán (Kwanga, different from ò̃sán above); and the minor villages of àjũ ́̃m (Yumu), àːʔʲɔ́ (Bakari), ámbú (Ambu shiri). Urcibar is actually more closely related to Shen (Laru) than to Rop.[2]
Ollop (Rop) is spoken in the major villages of àɾóp (Lopa town), ù̃jẽ ́mé (Gafara), rʷáːʃé (Raishe); and the minor villages of ʔʷéːɾà (Tungan Masu), ò̃sán (Bakin Ruwa), lópár (Lapar), áñ wá ̃ (Ana). Lopa speakers call themselves [dɔ̀ɾóp] (one person), [òːɾɔ́p] (many people), and the language [òlːɔ́p]. They refer to Urcibar speakers as [dɔ̀tʃíbár] (one person), [òːtʃíbár] (many people), and to their language as [ɘ̀ɹtʃíbár].[2]
