literature language linguistics africa design


Vowels are separated into low, rising, and high categories, which are presumably the only tonal delineations in Igbo. The notable absence of a corresponding “falling” tone, I first thought, creates problems for adapting the script to a language like Yorùbá, where, for example, the ọ̀ in Báyọ̀ carries a “falling” rather than a “low” tone when the sound is properly rendered. But on a second look, I find that what is meant as “rising” here is actually the same as a “mid” tone in Yorùbá.
