'sugarcoat' originates from the combination of 'sugar' and 'coat', where 'sugar' meant 'sweet substance' and 'coat' meant 'cover'.

'sugarcoat' changed from the literal meaning of covering something with sugar to a figurative sense of making something more palatable.

Initially, it meant 'to cover with sugar', but over time it evolved into its current meaning of 'to make something seem more pleasant'.
