verb (past and past participle lost /lɒst/)[with object]
- see heart.
Old English losian 'perish, destroy', also 'become unable to find', from los 'loss'
The verb lose is sometimes mistakenly written as loose, as in this would cause them to loose 20 to 50 per cent (correct form is ... to lose 20 to 50 per cent). There is a word loose, but it is very different—normally an adjective, meaning ‘untethered; not held in place; detached’, as in loose cobbles; the handle was loose; set loose.
