'negligibility' originates from Latin, specifically the word 'negligibilis,' where 'neg-' meant 'not' and 'legere' meant 'to choose or pick.'

'negligibilis' transformed into the French word 'négligeable,' and eventually became the modern English word 'negligible' through Middle English.

Initially, it meant 'not worth choosing or picking,' but over time it evolved into its current meaning of 'insignificant or unimportant.'
