Usage

What does sanction mean? Sanction has two main senses that are almost opposites: it can refer to authorizing or approving something, or to penalizing or disciplining someone or something. Sanction can be used as a verb (meaning to authorize or to penalize) or a noun (meaning approval or penalty). It is most commonly used in official contexts. As a noun referring to a penalty, it is especially applied to situations in which one country’s government imposes economic sanctions on another to try to force it to comply with laws or certain expectations. Example: Economic sanctions are intended to force regimes to play by the rules, but they often end up hurting the average citizen.

Etymology

Origin of sanction

First recorded in 1555–65; from Latin sānctiōn- (stem of sānctiō ), equivalent to sānct(us) (past participle of sancīre “to prescribe by law”) + -iōn- noun suffix; see -ion

Explanation

Sanction has two nearly opposite meanings: to sanction can be to approve of something, but it can also mean to punish, or speak harshly to. Likewise, a sanction can be a punishment or approval. Very confusing — the person who invented this word should be publicly sanctioned! See if you can guess the meaning of sanction in the following contexts. Before invading Iraq, the U.S. and its allies first imposed sanctions on the country, refusing to supply the country with much-needed trade items. Did you guess that sanction = "punishment"? You were right! But by trading with China at the same time, the U.S. quietly sanctioned that nation's known instances of human rights abuses. Did you guess that sanction = "approval"? You're right again!
