For those preferring "quotable facts", there's a summary of the video
interview at the Klingon Language Wiki:

{'an} a verb meaning to be a waste as in That's a waste.

Okrand:
"But it's not like 'I waste the Coca Cola'; you need -moH for that."
[...] "I sent him out there knowing he's not going to come back = I
sacrificed him. [it's with -moH] because I caused him to be a waste, I
caused that to be 'wasteful'."
