'quench' originates from Old English, specifically the word 'cwencan,' where 'cwencan' meant 'to extinguish or put out.'

'cwencan' transformed into the Middle English word 'quenchen,' and eventually became the modern English word 'quench.'

Initially, it meant 'to extinguish or put out,' but over time it evolved to include the meaning of 'satisfying thirst.'
