'autograph' originates from Greek, specifically the word 'autographos,' where 'auto-' meant 'self' and 'graphos' meant 'written.'

'autographos' transformed into the Latin word 'autographum,' and eventually became the modern English word 'autograph' through Middle English.

Initially, it meant 'self-written,' but over time it evolved into its current meaning of 'a person's signature.'
