'tolerant' originates from Latin, specifically the word 'tolerare,' where 'toler-' meant 'to bear or endure.'

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

Initially, it meant 'to endure or bear something,' but over time it evolved into its current meaning of 'showing willingness to accept or tolerate.'
