Etymology

Origin of competition

First recorded in 1595–1605; from Late Latin competītiōn-, stem of competītiō “agreement, rivalry,” from competīt(us) “agreed, met” (past participle of competere “to agree, come together, meet”; see compete ( def. )) + -iō -ion; sense influenced by competitor

Explanation

If you are trying to win or attempting to prove you're the best, you're in a competition. The word also describes your opponent in sports, business, and politics. If you're trying to beat out someone else — whether in the Olympics or a pie-baking contest — it's a competition, and the other contestants are called the competition too. If you describe something as a "friendly competition," you're saying the outcome isn't critical, or there's no money involved. If you do something impressive in order to win, people will say competition brings out the best in you. If you try to injure your opponent, they'll say it brings out the worst.
