Lose and loose differ by a single letter, which is exactly why they're so easy to mix up in writing — even though they aren't pronounced the same.
The Meanings
Lose (verb) means to no longer have something, or to fail to win.
Don't lose your keys again.
They expect to lose the match.
Loose, most commonly used as an adjective, means not tight, not firmly attached, or free from restraint.
This sweater is too loose on me.
The dog got loose from its leash.
How They Sound
This is the part most people miss: lose and loose are not pronounced the same.
- Lose rhymes with "choose" — /luːz/, with a voiced /z/ sound.
- Loose rhymes with "goose" — /luːs/, with a voiceless /s/ sound.
Say "choose" and "goose" out loud, back to back. That buzzing "z" versus the hissing "s" at the end is the only sound difference between lose and loose too.
Why the Confusion Happens
The mix-up is purely visual. "Loose" simply has one extra "o". Because the words look so similar on the page, it's easy for a slip in spelling to sneak past, especially while typing quickly.
Natural Examples
I don't want to lose this opportunity.
Make sure the handle isn't loose before you climb.
We can't afford to lose another game this season.
Her jeans were baggy and loose after she lost weight.
Memory Trick
Loose has an extra "O" — extra room, extra space, not tight. Picture that second "o" as the slack in a loose knot.
Another way in: remove one "o" from loose, and you lose it. The shorter word is the one about losing something.

Remember It
Lose is short and buzzes like "choose." Loose is longer and hisses like "goose." Same look, almost — completely different sound, completely different meaning.
