| petueu | s/he hears him/her | tshipetatin | I hear you |
The stem of these verbs alternates between u and a: the verb petueu has a stem that sometimes ends in u, and sometimes in a as in tshipetatin.
Here are some examples: petueu s/he hears him/her, tshipetun you hear me, tshipetatin I hear you, nipetakᵘ s/he hears me; natutueu s/he listens to him/her, tshinatutun you listen to me, tshinatutatin I listen to you, ninatutakᵘ s/he listens to me.
When conjugating verbs with alternating u stems, the alternative form of the stem ending in a is used in the following cases:
- With all inverse forms of the Independent; however, in the Western dialect, mixed inverse forms with a 4th person subject keep the stem ending in u, because they are conjugated differently.
