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

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

Initially, it meant 'able to distinguish or separate,' and this meaning has largely remained the same in modern usage.
