Is it o or oo ?

And why do 'above' and 'love' look a lot like 'lose' in their word structure, but don't sound like 'lose'? And why does 'blood' (with two oo's: note) have the same vowel sound as above or love? ... Welcome to the ridiculous world of English spelling. 'That's just the way it is.'

They are SPELLED differently because they are PRONOUNCED DIFFERENTLY.

"Lose" is pronounced with a soft "z" sound : "l-oo-ze"

"Loose" is pronounced with a hard "ss" sound : "l-oo-ss-e".

Don't try to be clever. YOU do not make the rules. You have to respect the rules which have existed for centuries, and which are used by everyone else. If you don't like them, too bad.

Lose is to misplace or be unaware of the location of something. If we lose something, it is lost. In contrast, loose is the opposite of tight. Clothes are loose if the size is too big for someone. Also, hanging loose means being very relaxed, as in loose as a goose.

Lose is the opposite of win, and loose is the opposite of tight. It's very confusing but again, English is a very hard language to learn, especially as an ASL.

Lose is the opposite of win. Loose is the opposite of tight. That's just the way it is. You might as well ask why your nose runs and your feet smell. Or why you drive on parkways and park on driveways...etc.

Because English spelling is not phonetic. There are historical reasons why lose is spelled that way.
