Oh no! That crazy man is back again and coming right towards us! Quick! Run in the opposite direction! Go the other way!
Opposite is an adjective that describes something found on the exact other side of a space—or even an idea. You say "black," I say "white": we're on opposite sides of the debate. You might notice the similarity of opposite to the nouns opponent and opposition or to the verb oppose. An opponent is someone you are matched against. To help remember opposite, think of a tennis match: two players oppose each other from opposite ends of the court.
