Morphology

mental + acuity

The noun is directly built from 'mental' (pertaining to the mind) and 'acuity' (keenness or sharpness), so the combined meaning 'sharpness of mind' is transparently derivable from the constituents. This is a straightforward adjective+noun composition following common cross-linguistic patterns, so a B1 learner who knows both words would understand it.

Etymology

Mental acuity comes from the picture of a 'sharp' mind: mental means mind and acuity means sharpness, like a sharp knife or a clear eye that notices small details quickly. So it means 'the ability to think quickly and clearly'.
