Ŏnĕipŏt is spoken by around 3000 people in southern Sudan and certain regions in Western Ethiopia. It is a member of the Nilo-Saharan language family, but because of its isolation Ŏnĕipŏt is not very closely related to other languages. Although an official orthography using the Latin alphabet was defined in 1978, the language still has no official status. The language is not educated in schools. Today Ŏnĕipŏt is still hardly ever written, but survives mostly as a spoken language.
Together with some Caucasian languages it is one of the few existing languages using the character ebreve. This character is often used for words with double-meanings. For example 'Ŏnĕi' can have the meaning 'real' and 'untrue', depending on the rest of the word.
