cover up
In political or legal contexts, this term carries a strong negative connotation, implying a deliberate and often illegal attempt to deceive the public or authorities. It suggests a calculated effort to suppress evidence or silence witnesses, distinguishing it from a simple mistake or accidental omission.
In a physical sense, the term is neutral and refers to the act of shielding something from the environment or adhering to social norms of modesty. When used intransitively regarding clothing, it often implies a requirement for propriety or protection against weather, rather than a desire to hide a secret.
