Yemba is one of the Cameroonian national languages that has been taught and written for 90 years. From a diachronic perspective, a lot of efforts have been made regarding the standardisation of this language, particularly the tone orthography. Despite achievements related to the awareness of the tonal phenomenon, the graphic representation of tones and the routes to handle the tone orthography, there remains a real challenge on the issue, namely designing efficient standard spelling norms. More so, important lessons can be drawn from the historical review of tone orthography in the Yemba language.
