'quenchable' originates from Middle English, specifically the word 'quenchen,' where 'quench-' meant 'to extinguish or satisfy.'

'quenchen' transformed into the modern English word 'quench,' and eventually became 'quenchable' by adding the suffix '-able.'

Initially, it meant 'capable of being extinguished,' but over time it evolved into its current meaning of 'capable of being satisfied or extinguished.'
