Usage

What’s the difference between loose and lose? 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 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 ends with an s sound and rhymes with moose. Lose ends with a z sound and rhymes with choose. 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 loose and lose 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 loose

First recorded in 1175–1225; (adjective) Middle English los, loos, from Old Norse lauss “loose, free, empty”; cognate with Old English lēas ( see -less), Dutch, German los loose, free; (verb) Middle English leowsen, lousen, derivative of the adjective

Explanation

If something is loose, it's not attached very securely to anything. Be sure the horse trailer attached to your truck isn't loose, or it might just roll away on its own while you're on the highway. Loose means "not fixed." We can use it for things that you physically attach, like doorknobs or buttons, or for ideas that aren't rigid. If someone has loose morals, they don't have a strong moral code. A floppy dancer has loose limbs, and a loose ball is one that no one's holding. It's also a verb. To loose something is to set it free, which is different from losing it. You loose the wild squirrel you nursed back to health.
