On the face of things, option 3 would be preferred, rendering '''ca'ai''', '''ka'ei''', '''nu'oi''' and '''nau'a''' redundant. And some people's understanding of '''ca'a''' et al is consistent with this. The snag is that '''ca'a''' et al are understood by others (including [[ma'oste]] gloss and Woldy) to involve an element of capability.

* I should add that I believe that originally '''ca'a/ka'e/nu'o''' were intended to have the meanings given above under (C), and the notion of capability crept in through a failure of understanding which then got cemented in official documents.
* But the argument pro pattern 3 is being revived: see [[CAhA as sumtcita|CAhA as sumtcita]].

** On the [[CAhA as sumtcita|CAhA as sumtcita]] page, I argue for A = 1 '''mu'ei''', B = 3 '''ca'a''', C = 3 '''nu'o'''. Therefore I am not in favour of any of '''ca'ai''', '''ka'ei''', '''nu'oi''' and '''nau'a'''.
