'autobiographer' originates from Greek, specifically the word 'autobiographia,' where 'auto-' meant 'self', 'bios' meant 'life' and 'graphein' meant 'to write.'

'autobiographer' changed from Greek 'autobiographia' into Late Latin/'autobiographia', passed into Modern French as 'autobiographie' and English as 'autobiography', and finally formed as the agent noun 'autobiographer' with the suffix '-er'.

Initially, it meant 'self-writing' (the act or account of writing one's life), but over time it evolved into the current meaning of 'a person who writes an account of their own life.'
