I have singled out a few verbs for review here because their patterns of conjugation are either irregular or difficult.
(1) ndapohkaaw vai-ąą he cooks
Difficulty: hidden vowel (ă) and shift in consonant from (d) to (t)
Nátpohkah
Kŭnátpohkah  
Ndúpohkaaw
Nàtpohkahnah 
Kŭnàtpohkahnah
Kŭnatpohkahnookw
Kŭnatpohkahmah
Ndúpohkaak
Explanation:
(nu) + (ndupohkąą) = nátpohkah
The prefix (nu) puts stress on the deleted vowel between (n) and (d)
This vowel turns out to be (a)
The cluster (nd) expands to (nat)
Ngataaw-ndapokah. I want to cook.
Ndapohkąątookw. Let’s cook.
Natpohkah wuyaaθ. I’m cooking meat. (s98)
