'discernibility' originates from Latin, specifically the word 'discernere,' where 'dis-' meant 'apart' and 'cernere' meant 'to separate or distinguish.'

'discernere' transformed into the Old French word 'discernir,' and eventually became the modern English word 'discern' through Middle English.

Initially, it meant 'to separate or distinguish,' but over time it evolved into its current meaning of 'the quality of being able to be perceived or recognized.'
