Sheko is an Omotic language of the Afro-Asiatic language family spoken in the area between Tepi and Mizan Teferi in western Ethiopia, in the Sheko district in the Bench Maji Zone. The 2007 census lists 38,911 speakers; the 1998 census listed 23,785 speakers, with 13,611 identified as monolinguals.
The language is notable for its retroflex consonants (Aklilu Yilma 1988), a striking feature shared with closely related Dizi and nearby (but not closely related) Bench (Breeze 1988). The Ethnologue lists the following linguistic features: "SOV; postpositions; genitives, articles, adjectives, numerals, relatives after noun heads; question word initial; 1 prefix, 5 suffixes; word order distinguishes subjects, objects, indirect objects; affixes indicate case of noun phrases; verb affixes mark person, number, gender of subject; passives, causatives, comparatives; CV, CVC, CVV, CV:C, CVCC; tonal, 3 tones."
