Morphology

of + age

The meaning 'having reached a particular age' is directly and transparently derived from combining 'of' (marking an attribute or relation) with 'age' (years of life); the phrase simply attributes age to the subject, so 'old enough' or 'legally adult' is predictable. This of + noun adjectival pattern is a common, compositional English structure and is cross-linguistically familiar, so a B1 learner who knows the constituents should infer the meaning.

Etymology

The phrase of age comes from old ways of saying someone was a certain age, meaning they had reached that number of years. So today of age is a short way to say 'old enough' or 'legally an adult', and it can also mean something has reached a set number of years.
