'slicer' originates from the English word 'slice', which comes from the Old French word 'esclice', meaning 'a splinter or fragment'.

'esclice' transformed into the Middle English word 'slice', and eventually became the modern English word 'slicer'.

Initially, it meant 'a splinter or fragment', but over time it evolved into its current meaning of 'a tool or person that slices'.
