'rasp' originates from Old French, specifically the word 'rasper', where 'ras-' meant 'to scrape'.

'rasper' transformed into the Middle English word 'raspen', and eventually became the modern English word 'rasp'.

Initially, it meant 'to scrape or rub with a rough tool', but over time it evolved into its current meaning of 'to make a harsh, grating sound'.
