Usage

What's the difference between lose and loose? Lose is a verb most commonly meaning to fail to win or to misplace something, as in I hate to lose in chess or Don’t lose your key. Loose is most commonly used as an adjective meaning not tight or free or released from fastening, attachment, or restraint, as in a loose screw or Let him loose! Lose ends with a z sound and rhymes with choose. Loose ends with an s sound and rhymes with moose. One reason that the two words are sometimes confused is that loose can also be used as a verb, most commonly meaning to free something from a restraint, as in loose the cannons! Perhaps the most common misuse of these words is when loose is used when lose should be. To remember the difference, remember this sentence: You could lose loose screws. (First comes the verb lose, with one o, followed by the adjective loose, with two o’s). Here’s an example of lose and loose used correctly in a sentence. Example: If you carry around loose cash, you could lose it—put it in your wallet. Want to learn more?

Etymology

Origin of lose

First recorded in before 900; Middle English losen, Old English -lēosan; replacing Middle English lesen, itself also reflecting Old English -lēosan; cognate with German verlieren, Gothic fraliusan “to lose”; see loss

Explanation

The verb to lose means something has gone missing. Maybe it's your car keys. Maybe it's points in a game. Maybe it's the love of your life. Sorry about that. You can physically lose something by misplacing it, or you can lose your pride in a competition. You can lose a game, you can lose your library book, you can lose money, you can lose your business, you can lose sight of your child, you can even lose your mind — basically, you can lose just about anything. Losing something is usually not a good thing, unless it's that annoying boyfriend or weight.
