'indolent' originates from Latin, specifically the word 'indolentem,' where 'in-' meant 'not' and 'dolere' meant 'to feel pain.'

'indolentem' transformed into the French word 'indolent,' and eventually became the modern English word 'indolent' through Middle English.

Initially, it meant 'not feeling pain,' but over time it evolved into its current meaning of 'lazy or avoiding activity.'
