'indiscretion' originates from Latin, specifically the word 'indiscretio,' where 'in-' meant 'not' and 'discretio' meant 'separation or discernment.'

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

Initially, it meant 'lack of discernment,' but over time it evolved into its current meaning of 'lack of good judgment or care.'
