jatlh SuStel:

<muS> jatlhpu' 'Iv? <parHa'> jatlhlu'pu'. pIm <-qangqu'> <'e' parHa'> je.

(Although we know we can put -Ha' on a lot of adverbials, we have no evidence we can put any other verb suffixes on them.)

rap <-qangqu'> <'e' parHa'> je not 'e' vIchup. 'a motlh cha'DIchmo' qaS wa'DIch.

It is interesting news to me that we have no evidence for other suffixes than -Ha' being used on adverbials. I know I've seen -qu' used thus by skilled speakers, though offhand I couldn't tell you who or when.
