Keliko (Kaliko) is a Central Sudanic language of the Democratic Republic of the Congo and South Sudan.
Omi was once considered a dialect.
A 2013 survey reported that ethnic Keliko reside in the following bomas of Morobo County, South Sudan. (Morobo County was reported to have a majority of ethnic Kakwa people.)
Ethnic Keliko are also found in Yei County, in Asole Boma (Lasu Payam).
Keliko is written in a Latin-based alphabet with frequent use of apostrophe, as well as the extra letters ẹ, á»Â, à Â, á»Â, and ụ and several digraphs and trigraphs. Diacritical marks are frequently used for marking tone.
