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.[2]
Sheko, together with the Dizi and Nayi languages, is part of a cluster of languages variously called "Maji" or "Dizoid".
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).
Phonology
Apart from the above-mentioned retroflex consonants, the phonology of Sheko is characterized by a total 28 consonant phonemes,[3] five long vowels and six short vowels,[4] plus four phonemic tone levels.[5]
Consonants
Hellenthal (2010, p. 45) lists the following consonant phonemes of Sheko:
Unlike other Dizoid languages, Sheko has no contrast between /r/ and /l/.[6] Consonants are rarely geminated,[7] and there is a syllabic nasal/n̩/[8]
Vowels
Hellenthal (2010, p. 56) lists the following long and short vowels of Sheko: /i/, /iː/, /e/, /eː//ə/, /a/, /aː/, /u/, /uː/, /o/, /oː/.
Tones
Sheko is one of very few languages in Africa that have four distinct phonemic tone levels.[9] Tone distinguishes meaning both in the lexicon and in the grammar, particularly to distinguish persons in the pronominal system.[10]
