'indulgent' originates from Latin, specifically the word 'indulgentem,' where 'indulgere' meant 'to be kind or tender.'

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

Initially, it meant 'to be kind or tender,' but over time it evolved into its current meaning of 'overly generous or lenient.'
