Morphology

mental + age

The meaning 'level of intellectual development expressed as an age' is directly and compositionally derived from 'mental' (relating to the mind or cognition) plus 'age' (a measure in years); a B1 learner who knows both constituents can infer this sense. This is a common cross-linguistic compound (e.g., Spanish 'edad mental', French 'âge mental') and follows a straightforward descriptive pattern, so it is transparent despite being a technical term.

Etymology

The phrase mental age comes from early intelligence tests that compared a person's thinking to the average abilities of different ages. It links mental meaning 'thinking' and age meaning 'years', so 'mental age' is the age whose average thinking level matches a person's ability.
