What's the difference between: Is it ok for you?, and: Is it ok with you?

What is the difference and in which context you can use:

Is it ok for you?

or:

Is it ok with you?

Solution 1:

Is it OK for you?

would be asked in order to confirm whether something provided for the other person is suitable for them, e.g. after giving them a cup of coffee.

Is it OK with you?

would be asked in order to gain agreement from the other person that a proposal is acceptable, e.g. "Is it OK with you if we meet at 6 instead of 7?"

Incidentally, the emphasis in the pronunciation is generally not the same for both. In the first the stress is usually on the "K" of "OK". In the second, the stress is on "you".

Solution 2:

ELL is the right place for posting such doubts.

Keeping it simple,when we say something is ok with us, it means that it is agreeable to us. However, when we say something is ok for us, it means that it is convenient for us. For example:

A: How about having Korean food for dinner tonight?

B: Sure. That’s ok with me. I like Korean food.

A: I’d like to get together with you at 3:00 this afternoon. Is that time ok for you?

B: I’m afraid not. I have another appointment at 3:00, but 4:30 is ok for me.
