'self-accuse' originates from the combination of 'self' and 'accuse', where 'self' refers to one's own person and 'accuse' comes from Latin 'accusare', meaning 'to call to account'.

'accusare' transformed into the Old French word 'acuser', and eventually became the modern English word 'accuse'.

Initially, it meant 'to call to account', but over time it evolved into its current meaning of 'to charge with a fault or offense'.
