Morphology

steel + trap

The image combines 'steel' (strength, hardness) and 'trap' (a device that captures), so a learner who knows both words can plausibly infer a metaphorical meaning of a mind that 'captures' or holds things strongly. The connection is metaphorical and involves a transfer of physical properties to mental ability, so the precise nuance (rapid comprehension and retention) is not fully predictable without exposure.

Etymology

Steel trap is an expression that compares a very quick, sharp mind to a real steel trap, whose jaws snap shut and hold things tightly. That's why calling someone a steel trap means their memory or thinking is very quick and does not let go, or 'very quick to notice or remember'.
