'aftertimes' originates from Middle English, specifically the word 'after' combined with 'time', where 'after' meant 'following' and 'time' referred to a period or duration.

'after' combined with 'time' in Middle English to form 'aftertime', and eventually became the modern English word 'aftertimes' as its plural form.

Initially, it meant 'times following a specific event', and this meaning has largely remained the same in modern usage.
