'superannuated' originates from Latin, specifically the word 'superannuatus,' where 'super-' meant 'beyond' and 'annus' meant 'year.'

'superannuatus' transformed into the French word 'superannuer,' and eventually became the modern English word 'superannuated' through Middle English.

Initially, it meant 'beyond the years,' but over time it evolved into its current meaning of 'outdated or retired due to age.'
