This article uses the example of Kabiye, one of the national languages of Togo, to illustrate the way in which miscues (errors in reading) can be a result of a toneless orthography being applied to a tone language. However, the author finds that the non-representation of tone in the orthography only accounts for a part of the problem. Hidden or unclear morpheme boundaries can have a greater effect, both in themselves and in the fact that they can further conceal tone by masking the roots of morphemes. The author suggests that, if the roots were made explicit, tone could be deduced to a much greater extent without having to be written.
