Morphology

knock + off

The particle 'off' can signal cessation or removal, which gives a cue toward 'stop', but the verb 'knock' (to hit) does not independently convey stopping; the imperative use ('knock it off') is conversational and idiomatic. Because the meaning relies on a conventionalized phrasal-verb use rather than straightforward compositional semantics, a B1 learner who only knows the constituent words would likely need prior exposure to fully understand it.

Etymology

Knock off as 'to kill' may come from the violent image of knocking someone off their feet, a hit that puts them down for good. That's why criminals use it to mean 'to kill'.
