'reside' originates from Latin, specifically the word 'residere,' where 're-' meant 'back' and 'sedere' meant 'to sit.'

'residere' transformed into the Old French word 'resider,' and eventually became the modern English word 'reside' through Middle English.

Initially, it meant 'to sit back or remain,' and over time it evolved into its current meaning of 'to live or dwell in a place.'
