Morphology

gray + matter

The primary anatomical meaning (‘the darker tissue of the brain’) is directly and compositionally derived from 'gray' (a color) + 'matter' (substance), so a B1 learner who knows both words can infer the literal sense. The extended informal meaning 'intelligence' is a motivated metaphor based on the literal brain tissue sense and is therefore largely inferable from the constituents and cross-linguistically familiar.

Etymology

The noun gray matter names the darker part of the brain and the words gray and matter give the image of brain 'stuff' that looks gray. Because this part does the thinking, calling someone's gray matter means their 'intelligence' or 'brainpower'.
