sanction

What does "sanction" mean?
The word "sanction" is unique because it holds two contradictory meanings. It can mean to give official permission or approval for something, or it can mean to impose a penalty, such as a trade embargo or legal restriction, to force compliance. Think of it as the ultimate exercise of authority: you are either opening the gate with a blessing or slamming it shut as a punishment. In formal and political contexts, you will most often see it used in the sense of "imposing sanctions." When used to mean approval, it often appears in legal or institutional settings, such as "official sanction." Because of this dual meaning, context is everything; always look for clues like "approved" versus "imposed" to determine whether the subject is being rewarded or punished.
