'endurable' originates from Latin, specifically the word 'endurabilis,' where 'endurare' meant 'to make hard or strong.'

'endurabilis' transformed into the Old French word 'endurable,' and eventually became the modern English word 'endurable' through Middle English.

Initially, it meant 'capable of being hardened or strengthened,' but over time it evolved into its current meaning of 'capable of being endured or tolerated.'
