TKD-A adds the meanings of "request, plead."

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.

How do Klingons talk about praying to and worshipping religious figures? The context is specifically about Kahless.

For “pray,” when appropriate, you can use words like qoy’ “plead, beg” and tlhob “request, ask, plead,” but there’s a specific word for “pray to” or “entreat” or “implore” or “beseech” a religious (or similar) figure: qIw.

To “worship” as part of a religious belief or rite or service (that is, or to worship a deity or revered figure in that sort of context), the verb is ’am.

To “worship” or “adore” something/someone in a more secular sense (like “I worship the ground you walk on”), the verb is voj.
