As part of a religious belief or rite or service.

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.
