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

'blētsian' changed from the Old English word 'blētsung' 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.'
