I don't see the suffix "Qo'" as being from the Klingon Dictionary.
What type number of suffix is it? Where did it come from?
It's a verb suffix of type "rover" which means "Don't/Won't". See Section 4.3 page 47 of TKD.
But despite its classification of rover, it must always come between any type 8 and type 9 suffixes. It doesn't actually "rove."
