Morphology

rap + on + the + knuckle

The literal parts (a 'rap' as a quick blow and 'knuckles' as finger joints) directly evoke a small physical strike, so a learner could plausibly infer a sense of mild punishment. However, the common usage meaning 'to reprimand or punish mildly' depends on a figurative extension from physical hitting to rebuke, which is not fully predictable without exposure.

Etymology

The idiom rap on the knuckles comes from the image of a teacher giving a quick rap to a child's knuckles with a ruler as a small punishment. So the phrase now means 'to criticize or punish someone mildly'.
