What Happens When “Loose” Loses an “O”?

powered by LanguageTool

“Loose” is an adjective, and “to lose” is a verb. But why is there confusion when it comes to the forms “looser” and “loser”?

We use "loose" as an adjective, whereas "(to) lose" appears mostly as a verb.
Both words are correct—but when should you use them?
Correct Use

  • Loose is most often used as an adjective, but can also be used as a verb or noun.
  • Whereas (to) lose is a verb that means “to be unable to continue possessing” or “maintaining/to suffer defeat/to be unable to find something again.”

“Loose” versus “Lose”—What's the Difference?

Every so often, the most ordinary words can cause the greatest difficulty in our everyday language. The words lose and loose, for instance, are spelled nearly the same, but have very distinct meanings. The confusion results in people mixing up their meanings, their basic forms, and their modified forms (with suffixes). We will explain all possible variations of both words, and include definitions and examples.

By the way, if you listen carefully, you can hear the difference: Loose /luːs/ has a voiceless “s” sound and rhymes with “the use,” while (to) lose /luːz/ has a softer “s” and rhymes with “to use.” You can feel vibrations in your throat only for the second one.

The Main Challenge: Loose or Lose?

The confusion between loose and lose arises from the many parts of speech both words can serve as. Generally speaking, we use loose as an adjective, whereas (to) lose appears mostly as a verb. Both words have several distinct, and sometimes even overlapping meanings.

Loose (Adjective)

  1. (physically) not fastened, held, secured, arranged, or combined; not solid
  2. figuratively detached from anything; free
  3. not fitting tightly

Lose (Verb)

  1. to be unable to continue possessing or maintaining
    also: to suffer deprivation
  2. to fail to win, to suffer defeat

  3. to be unable to find something again
    also: to get rid of something

While (to) lose predominantly serves as a verb, loose can appear as an adjective (see above), but also more rarely as a noun, or even as a verb.

  • to be at a loose end, to hang loose, to let something loose, to turn something loose, to stay loose, to set loose, to cut loose, to cast loose, to break loose, to tear loose.

But if you have lost an “o,” then you are lose the first definition.

The Second Step: Looser or Loser?

The challenge of distinguishing the two words doesn’t stop there, unfortunately. There are several modifications of both lose and loose:

  • The verb, lose, has a third-person form: loses. For its past tense, you need to use lost and (have) lost, whereas its gerund form is losing.
  • The adjective, loose, has a comparative form, meaning that something is looser than something else. Something might also be the most loose, or the 'loosest' (superlative form of 'loose').
  • From its function as a noun, loose can derive looses, loose’s, and looses’.
  • Loose (as a verb) can carry the same inflections as its counterpart lose, which makes the distinction even more perplexing: looses, loosed, (have) loosed, loosing.

Besides these direct modifications, there are even more expressions related to both words:


  • Looseness (noun, the quality of being loose):
    The looseness of this definition is recognizable to everybody.
  • (to) Loosen (verb, synonym for (to) loose), including loosens, loosened, loosening:
    You have to loosen the knot before you can use the sail.
  • Loosely (adverb, similar to the adjective loose):
    The keyboard was still loosely connected to the computer.
  • Loosie / loosey (informal noun, US English, individually sold cigarettes).
    Do you have a loosie for me, too?


  • Loss, lossage, losings (money) (nouns, the result of losing something):
    It’s their loss if they prefer not to meet us.
  • Losable (adjective, describing something that is likely to get lost):
    Your purse is so small! It would be too losable for me.
  • Loser (noun, someone who loses all the time), including losers:
    Your dad is such a loser!
  • Loserdom, loserness, loserhood (nouns, characteristics of being a loser):
    Due to his loserdom, he doesn’t have much money.
  • Lost (adjective, unable to find the (metaphorical) way, or the direction):
    We were getting lost, as you didn’t return our calls.
  • Lostness (noun, the state of being lost):
    She was well-known for her lostness.

As you can see, there are a large number of possible word derivations. So, the terms loser and looser both exist, and have entirely different definitions; this is where the confusion is at its peak.

“Loose” or “Lose”—Which One is Correct?

Please Remember

Imagine that you are trying to double the “o” by making the word a bit looser.

But if you fail, you’re a loser because the second “o” can't fit.

Although there are many different forms of lose and loose, the following constructions are never correct:

  • Lose’s and loses’ (as lose is never a noun),
  • losest and losely (as lose is never an adjective),
  • loosers and loosers’ (as looser is never a noun),
  • losen, losens, losened, losening (as losen is not a word)

Even if this seems like quite the number of potential forms of lose and loose, LanguageTool always knows which term to use. As an intelligent spelling and grammar checker, it corrects errors as you type and combines your loose ideas into a flawless text. You’ll never lose your words again—especially with the practical synonym feature, which helps you to distinguish between the several meanings of lose and loose.
