sanction
This word is a rare auto-antonym, meaning it can express two opposite concepts depending on the context. In a positive sense, it functions as a stamp of legitimacy, conveying a feeling of authority, legality, and formal endorsement. It is often used in legal or ecclesiastical settings where a higher power grants a green light to an action. In a negative sense, it describes a tool of punishment or diplomatic pressure. This usage carries a heavy, restrictive tone, evoking images of frozen assets, trade embargoes, and isolation. The shift in meaning usually depends on whether the word describes granting a right or removing a privilege.
Countable when referring to a specific penalty or a particular act of approval (a sanction). Uncountable when referring to the general concept of official authorization.
