Morphology

mental + capacity

The meaning 'intellectual ability' is directly and compositionally derived from 'mental' (relating to the mind) + 'capacity' (ability), so a B1 learner who knows both words can readily infer the MWE. This adjective+noun combination follows a transparent, cross-linguistically common pattern for expressing types of ability, so its sense is predictable without prior exposure.

Etymology

Mental capacity is a picture of the mind as a container. The mental part is the mind and the capacity part is the amount a container can hold. So it means 'the ability to understand, think, and make decisions'.
