"OED to prove that the right word and the wrong word were the same word in the 14th Century."

Again, since this seems to be unclear to you, the OED says that feint is an acceptable form of faint in the sense of timid.

But perhaps you know better than the OED. You are the spelling police. LOL

I know enough not to use the OED as my source for American language norms.
