'smear' originates from Old English, specifically the word 'smerian,' where 'smer-' meant 'to anoint or rub with oil.'

'smerian' transformed into the Middle English word 'smeren,' and eventually became the modern English word 'smear.'

Initially, it meant 'to anoint or rub with oil,' but over time it evolved into its current meaning of 'to spread or apply a substance.'
