'autonomous' originates from Greek, specifically the word 'autonomos,' where 'auto-' meant 'self' and 'nomos' meant 'law.'

'autonomos' transformed into the Latin word 'autonomus,' and eventually became the modern English word 'autonomous' through Middle English.

Initially, it meant 'self-governing or having its own laws,' but over time it evolved into its current meaning of 'independent or self-sufficient.'
