'pinafore' originates from English, specifically the combination of 'pin' and 'afore,' where 'pin' meant 'to fasten' and 'afore' meant 'in front.'

'pinafore' changed from the English phrase 'pin afore' and eventually became the modern English word 'pinafore'.

Initially, it meant 'a garment pinned in front,' but over time it evolved into its current meaning of 'a sleeveless garment worn over other clothing.'
