'blessing' originates from Old English, specifically the word 'blētsung,' where 'blētsian' meant 'to consecrate or make holy.'

'blētsung' transformed into the Middle English word 'blescing,' and eventually became the modern English word 'blessing.'

Initially, it meant 'to make holy or consecrate,' but over time it evolved into its current meaning of 'a beneficial thing or prayer for divine favor.'
