'exhaustible' originates from Latin, specifically the word 'exhaurire,' where 'ex-' meant 'out' and 'haurire' meant 'to draw or drain.'

'exhaurire' transformed into the French word 'exhaustible,' and eventually became the modern English word 'exhaustible' through Middle English.

Initially, it meant 'to draw out completely,' but over time it evolved into its current meaning of 'capable of being used up or depleted.'
