'accusable' originates from Latin, specifically the word 'accusabilis,' where 'accusare' meant 'to call to account.'

'accusabilis' transformed into the Old French word 'accusable,' and eventually became the modern English word 'accusable' through Middle English.

Initially, it meant 'capable of being called to account,' but over time it evolved into its current meaning of 'capable of being accused or charged with a crime or offense.'
