Major derivation

Major derivation is highly complex, but probably mostly regular; irregular forms often split off into their own verbs.

- Disyllables to which lengthening applied are unstable:
*damzo > dnããɹ
*damzodamzo > dnæɹodnæɹo
*dulo > duul
*dulodulo > dulodulo
*karu > kaar
*karukaru > kærokær
*kimu > kææmʷ
*kimukimu > kimʷukimʷ

Wherestern Whatic semivowel nasalization produced some alternations:
*semra > yĩĩn
*semrasemra > ɲɨnæɲɨnæ

How does this work, anyway?
