Morphology

knock + out

The literal sense 'to render unconscious' is transparently built from 'knock' (to strike) + 'out' (into an unconscious state), and the figurative sense 'to impress or overwhelm' is a metaphorical extension of that physical impact. This metaphorical transfer is partially predictable but not fully obvious to a B1 learner who has not encountered the idiomatic use, so the expression is only partially transparent.

Etymology

Knock out — The sense 'to impress' comes from the image of being stunned or overwhelmed, as if a great show or person has hit you hard and left you speechless. That's why knock out is also used to mean 'to impress or overwhelm someone greatly'.
