Reconstruction
The impositive form *-bùmbɪka "to put in the ashes to bake" appears mainly in Eastern Bantu, and may not be reconstructable to the level of Proto-Bantu. It often loses its impositive sense and replaces the original *-bùmba, except when the underived form gains a more specialized meaning. The meaning sometimes generalizes away from cooking to mean burying or covering an object. Forms with the separative extensions *-ʊk-/-ʊd- can shift from "remove from ashes" to more general meanings such as "uncover; discover; reveal". A sense of bringing an animal out of hiding results in even more divergent meanings such as "rouse the game", "wake up", "dash out", or "stampede".
