'indelicate' originates from Latin, specifically the word 'indelicatus,' where 'in-' meant 'not' and 'delicatus' meant 'dainty or delicate.'

'indelicatus' transformed into the French word 'indélicat,' and eventually became the modern English word 'indelicate' through Middle English.

Initially, it meant 'not delicate or dainty,' but over time it evolved into its current meaning of 'lacking sensitivity or tact.'
