Definition of whitewash

The term "whitewash" originates from the practice of using a mixture of chalk and water to cover flaws and blemishes on walls and surfaces. This practice dates back to the 16th century. Over time, the term evolved to describe concealing or covering up unpleasant or embarrassing situations, like a politician using a press conference to gloss over a scandal. This metaphorical meaning first appeared in the 19th century, emphasizing the act of hiding something unpleasant with a superficial layer of white paint.
