'ablush' originates from Middle English, specifically the word 'blushen,' where 'blush' meant 'to redden or become red in the face.'

'blushen' transformed into the modern English word 'ablush' through the addition of the prefix 'a-' to indicate a state of being.

Initially, it meant 'to become red in the face,' and this meaning has largely remained the same in modern usage.
