'scratcher' originates from the English word 'scratch,' which comes from Middle English 'scracchen,' meaning 'to scratch or scrape.'

'scracchen' transformed into the modern English word 'scratch,' and 'scratcher' was derived from it by adding the suffix '-er' to denote a tool or person that performs the action.

Initially, 'scratcher' referred to a person or tool that scratches, and this meaning has largely remained the same in modern usage.
