'perpetual' originates from Latin, specifically the word 'perpetuus,' where 'per-' meant 'through' and 'petere' meant 'to seek.'

'perpetuus' transformed into the Old French word 'perpetuel,' and eventually became the modern English word 'perpetual' through Middle English.

Initially, it meant 'lasting through time,' but over time it evolved into its current meaning of 'never-ending or constant.'
