Cicipu ([tʃìtʃípù], ISO 639–3 code awc) is spoken by approximately 20,000 people in northwest Nigeria, with the main language area straddling the boundary between Kebbi and Niger states. The language belongs to the Kambari subgroup (not Kamuku as stated by Lewis, Simons & Fennig 2013) of Kainji (Benue-Congo), although it is heavily influenced by the lingua franca Hausa, in which almost all speakers are fluent. There are several identifiable dialects, with native speakers of Cicipu generally listing seven. Of these, Tirisino is the most prestigious and least endangered dialect, and this is the one presented here. Tikumbasi is the most divergent of the dialects, with the /o/ vowel in the other dialects consistently corresponding to /e/ in Tikumbasi (for example /póːpò/ ‘hello’ ~ /péːpè/, /tʃìkóːtò/ ‘drum’ ~ /tʃìkʷéːtè/). The distinction between /o/ and /ɔ/ has been lost in Tikumbasi.
