Word of the Day -- Catercorner

Here's a fun word.  When I was a kid, my mom used to say kittycorner and my dad said, "No, it's catercorner."  They were both right, both are acceptable uses of the definition, which is "something in a diagonal or oblique position".  What's interesting to me is that two derivatives, kittycorner and cattycorner both take "cater" and turn it into something feline related, when in actual fact it is from the Middle French word quatre (or catre) and means the number "four" in English.  The English in turn adopted the word to refer to the 4 dotted side of dice.  Perhaps because a 4 dotted die can suggest an "X", cater eventually came to refer to something that is diagonal from something else.  Eventually "corner" was added to become catercorner.
