Ukaan (also Ikan, Anyaran, Auga, or Kakumo) is a poorly described Niger–Congo language or dialect cluster of uncertain affiliation. Roger Blench suspects, based on wordlists, that it might be closest to the (East) Benue–Congo languages (or, equivalently, the most divergent of the Benue–Congo languages). Blench (2012) states that "noun-classes and concord make it look Benue-Congo, but evidence is weak."
Speakers refer to their language as Ùkãã or Ìkã.
The name Anyaran is from the town of Anyaran, where it is spoken. Ukaan has several divergent dialects: Ukaan proper, Igau, Ayegbe (Iisheu), Iinno (Iyinno), which only have one-way intelligibility in some cases.
Salffner (2009: 27) lists the following four dialects of Ukaan.
- Ikaan: spoken in Ikakumo and Ikakumo (Edo State)
- Ayegbe: spoken in Ise
- Iigau or Iigao: spoken in Auga
- Iino: spoken in Ayanran
Ethnologue lists the following locations where Ukaan is spoken.
- Ondo State: Akoko North-East LGA
- Edo State: Akoko Edo LGA
- Kogi State: Ijumu LGA (Anyaran, Auga, and Ishe towns)
Proto-Ukaan has been reconstructed by Abiodun (1999).
