  • The example link that you gave me is about by me and with me but my question is why in that phrase "by me" and not "for me"

  • "By me" in this context means something like "according to me", "in my opinion". You may think that "for me" would be more logical, but "That's fine by me" is just an idiom. Commented Dec 2, 2019 at 9:48
  • @Να είστε αισιόδοξοι OK. Considering more similarity between the versions 'fine with/by', here's an explanation of the difference between 'fine for/with' me, by Brian Hartman: quora.com/… "It's fine for me." means some particular thing (object) is satisfactory to you. A coat may be fine for you. A cup of tea may be fine for you. But it's a thing. "It's fine with me." usually refers to a course of action

This is precisely meaning 3 in the Oxford Learners':

(also used as an exclamation) used to tell somebody that an action, a suggestion or a decision is acceptable

‘Bob wants to know if he can come too.’ ‘That's fine by me.’

"Fine by me" is a phrase that simply means "I think that's acceptable".


As far as I understand, 'this seat seems fine for me' implies that I can seat (myself) in.

While 'this seat seems fine by me' implies that in my opinion, anyone (else) might seat in it.

Funny, isn't it?

    Yes, language is sometimes strange, especially where idioms are involved. Fine by me is an idiom meaning "I accept/approve/have no objection".
