Historical changes

Nyole has an interesting development from Proto-Bantu *p → Nyole . Schadeberg (1989) connects this sound change to rhinoglottophilia, where the sound change developed first as  →  → . Then, given the acoustic similarity of  and breathy voice to nasalization, the sound change progressed as  →  → . The velar place of articulation development is due to velar nasals being the least perceptible of the nasals and its marginal status in (pre-)Nyole and other Bantu languages. In closely related neighboring languages, *p developed variously into  or  or was deleted. This historical development results in so-called "crazy" alternations, like  resulting in  as in the following:

 n-ŋuliira ("hear" stem form) : puliira "I hear"
 n-ŋumula ("rest" stem form) : pumula "I rest"

In the above two words, when the first person singular subject prefix  is added to the stem starting with , the initial consonant surfaces as . In other forms (like  "to hear" and  "to rest"), the original stem-initial  can be seen. Writing System
