What does loose mean and what does lose mean?
Loose is an adjective meaning not firmly fixed or not fitting tightly, and it survives as a rare verb meaning to set free. Lose is a verb meaning to no longer have something, to misplace it, or to fail to win. The Cambridge entry for loose and the Cambridge entry for lose confirm the split, and one line shows it: a loose hinge wobbles, and you lose a glove.
| Sense | Word | Plain meaning | Example |
|---|---|---|---|
| Not firmly fixed | loose | Not firmly attached | One bolt on the shelf is loose. |
| Not fitting tightly | loose | Baggy or roomy | He wore a loose shirt all summer. |
| Free from control | loose | Set free, a rare verb | The keeper loosed the dogs at dusk. |
| No longer have | lose | Misplace or forfeit | Do not lose the spare key. |
| Fail to win | lose | Be beaten | Our team may lose on Saturday. |
| Let fall away | lose | Shed or reduce | The company lost money last year. |
The adjective sense of loose covers objects and clothing, while the verb lose always needs a subject that does the losing. That is why the two words can never swap places without breaking the sentence.
What is the difference between loose and lose?
The difference is word class first and meaning second. Loose describes a noun, so it sits beside it or after a linking verb; lose shows an action, so it needs a subject to perform it. A one-letter trap such as abel vs able fails for a similar reason, and another spelling pair, addition vs edition, shows how one letter can shift a whole meaning.
| Test | Loose | Lose |
|---|---|---|
| Part of speech | adjective, rarely a verb | verb |
| Core meaning | not tight or not fixed | to no longer have |
| Typical role | describes a noun | shows an action |
| Sound at the end | a hissing s, as in goose | a buzzing z, as in whose |
| Spelling clue | double o, as in too | single o, as in do |
| Common phrase | a loose screw | lose a match |
Choose loose when you are describing something that is not tight or not fixed, and choose lose when the sentence needs the action of losing.

Register makes no difference here, because the two words are not rivals in the same slot. The test is always grammatical: if you need a describing word, choose loose, and if you need an action word, choose lose. Say the pair aloud, hearing the z sound in lose, and the spelling will follow the sound. A quick check is to swap in a known pair: if tight fits the slot, the adjective loose is wanted, and if find does not fit an action slot, the verb lose is wanted.

Frequently asked questions about loose and lose
Why do people confuse loose and lose?
The two spellings differ by a single letter, and in fast typing the eye and hand treat them as the same shape. Their meanings are also loosely related to letting something go, which blurs the choice. Word class is the reliable test: loose describes and lose acts.
Is loose ever a verb?
Yes, but rarely. Loose works as a verb meaning to set free or release, as in loosed the dogs, and it appears mostly in older or literary writing. In everyday use the verb is almost always lose. The related verb loosen, meaning to make less tight, is far more common than loose as a verb.
What is the past tense of lose?
The past tense and past participle of lose are both lost, as in we lost the match and the key is lost. The form loosed belongs only to the rare verb loose, meaning released. Mixing them up, as in loosed the match, is a common slip.
Is there a sound trick to tell them apart?
Yes. Loose ends with a light hissing s, while lose ends with a buzzing z, so the words rhyme with goose and whose. The spelling follows the same pattern: a double o like too signals the s sound, and a single o like do signals the z sound.
