Lose vs. Loose: What's the Difference?

Quick Answer

lose (1 "o") = verb — to misplace something or fail to win

loose (2 "o"s) = adjective — not tight, not firmly attached

Explanation

LOSE (verb) — one "o"

To be unable to find / to fail to win

lose → lost → lost

"Don't lose your keys."

"We might lose the game."

"I always lose track of time."

LOOSE (adjective) — two "o"s

Not tight, not firmly attached, free

opposite: tight, fixed, secure

Memory trick: "loose" has a double-o that has come loose — two o's floating free. "lose" rhymes with "whose" and "choose" — single-o verb.
