"Can we trust him?"
A thought just hit me. Sure, it's perfectly clear, but the way that suffix types are described in The Klingon Dictionary, i.e. the way that they must be used in order; and that two suffixes of the same type can't be used in a word, would be mind-shattering to me (very time-consuming to say the least). I mean that the progression by which I've learned here has made it all seem very natural, and almost obvious.
