Lose - loose
From Hull AWE
Lose and loose are quite often confused. Do not make this mistake!
- To lose means basically the opposite of 'to find'. In a later development, it is the opposite of 'to win'. It is pronounced with a 'z' sound at the end, IPA: /lu:z/. The past (tense and participle) is lost; the third person singular of the present tense is loses. (See lose (irregular verb).)
- To loose, as a verb, means 'to untie', or 'let go'. It is pronounced with an '˜s' sound, IPA: /lu:s/. The past (tense or participle) is loosed. A cowboy may loose his horse into the open field. (It is close to the verb to loosen, which means 'to make less tight'. A man may loosen his tie, in order to breathe more easily.)
- There is also an adjective loose. It is the opposite of 'tight'.
