'shaver' originates from the Old English word 'sceafan', which meant 'to scrape or shave'.

'sceafan' transformed into the Middle English word 'shaven', and eventually became the modern English word 'shave', from which 'shaver' is derived.

Initially, it meant 'to scrape or shave', but over time it evolved into its current meaning of 'a device or person that shaves'.
