Hi Sue,

However your use of vocabulary in the other sentences is fine.

Is my use of the term fine too?

Hi Sue,
Is my use of the term fine too?

No. Fine is only used in affirmative sentences, for example :

How are you?
I'm fine.But not : *I'm not fine / *Are you fine? (The asterisk means it's not correct.)

So, a conversation might go :

Is that OK?
Yes, that's fine or
No, it's not OK

with OK being used instead of fine in interrogative/negative contexts.

So your use of fine was wrong because you used it in an interrogative.

This is what is called colligation - the tendency for a word to occur, or be restricted to, specific grammatical contexts. It happens quite a lot and is one of the things that makes language learning soooo difficult.
