Okrand, HolQeD 7:4: What I wanted to do with tlhob and ghel is to distinguish between two different meanings for the English verb "ask." There are two "ask's." There's the "ask" where you ask a question and there's "ask" where you make a request. I wanted it to be two different verbs, though apparently there are times when the "request" verb is used to ask a question as well [PK: lutlhob naDevvo' vaS'a'Daq majaHlaH'a'?] So maybe the way it works is that ghel can ask a question and only ask a question and the other one can mean that and is also used to request or plead or something like that.
