1. make something seem less unpleasant or negative than it really is
Professional
Social
sugarcoat the truth/fact/opinion
This expression, adapted from the process of coating medicine, particularly tablets, with sugar in order to disguise the unpleasant taste and therefore make them easier to swallow, is used to refer to making something bad seem more acceptable, or easier to cope with and accept. Usually this is done through speech, and can often involve lying, or, at the very least, witholding the full truth of something. It is common in both a social and professional context, and shares a similar meaning to the phrases 'whitewash' and 'gloss over.'
