Paul Simon wrote a song entitled "Thinking too much". In it he makes reference to analyzing a love affair. Just when we think we have it, we don't. Not that we shouldn't think, but often it's when we think too much that we make mistakes. Rather we should just let it happen as it is supposed to happen.
Such is the case with today's typo: Affiar. The "i" and the "a" are separated quite a bit on the keyboard. Perhaps because we are thinking too much about it, we stroke the "i" key first. As a matter of fact, it has been done 105 times in OhioLink.
This is one that originally appeared in the B list, but in actuality now must be promoted to the A list (those of highest probability) in the Typographical errors in library databases.
