This is the American Editor, a trade publication for people whose business it is to make sure words aren't spelled wrong. Can you spot the typo? Yes, it's on the cover.
And no, I don't think it's a pun.
I also caught a major slip-up within (technically two, if you count Associated Press style for complete sentences). See it?
Hint: It's the guy's name.
These probably aren't accidental. I think they're trying to keep us on our toes.
