I used "eery" yesterday in a text and was corrected jokingly by my correspondent to "eerie." Looking at it after the fact, neither 'looks' right to me and both get through auto-correct with no red underline. Some cursory googling showed that both are at least technically correct, but I'm curious as to preferred or standard usage. I read a lot and I guess I've rarely seen the word in print, and even then it was probably the adverb form eerily.
So, beyond actual correctness, are both equally acceptable? Regional differences?
