Orthography Oko is a language without a working orthography. Although some educated members of the Oko speaking communities have at one time or the other proposed an orthography for the language, for example, Akerejola (1971) and Adegbija (1993), none of their proposals have been duly given much recognition due to lack of literacy in the language.
