- I always loose my umbrella when it rains.→ lose (verb needed)
How do you tell them apart when spelling?
The clearest test is pronunciation. Loose has a soft, hissing 's' sound and rhymes with goose, moose, and juice. Lose has a 'z' sound and rhymes with choose, whose, and news. Saying the word aloud slowly usually reveals which spelling you need.
A second clue is the grammar: loose sits before a noun or after 'be' (feels loose, a loose fit), while lose takes a direct object and changes form with tense (lose, lost, losing).
