All right, here’s the skinny: After all vs. afterall

Among the common grammar errors I’ve spotted during my many years of editing is the use of “afterall.” This probably arises from the same inclination to make “all right” one word by combining them to become “alright.” Alas, “after all,” meaning “in spite of contrary views or expectations” is always two words. In short, “after all” is all right, “afterall” isn’t.
