'age-related' originates from the combination of 'age' and 'related', where 'age' refers to the length of time a person has lived or a thing has existed, and 'related' means connected or associated with.

'Age-related' is a modern English term formed by combining 'age' and 'related', both of which have roots in Old English and Latin.

Initially, it meant 'connected to age', and this meaning has remained consistent in modern usage.
