By the way, I don't know for sure what "take revenge" means, but what
about {noD} "retaliate"?

SuStel: 

"Take revenge" has an important emotional component that "retaliate"
lacks.

I'm not sure that's true of {noD}:

batlh Heghlu'chugh noDnISbe' vay' 
An honorable death requires no vengeance. TKW

cheQIHchugh manoDbe''a' 
Wrong us, shall we not seek revenge? TKW

nurraj nIHlu'ta'mo' manoD 
We will avenge your stolen pride ["dignity"] (PB early draft)

le'yo'raj nIHlu'ta'mo' penoD jatlh qeylIS 
And Kahless spoke to them ... about avenging their stolen pride PB
 
Klingons may not distinguish between the two ideas; that is, they may take all these matters personally.

Ah! Then I take it back; noD is the perfect verb for take revenge!
