Did You Know?
"Catercorner" also has the variants "kitty-corner" and "catty-corner," but despite appearances, no cats were involved in the creation of this word. "Cater" derives from the Middle French noun "quatre" (or "catre"), which means "four." English speakers adopted the word to refer to the four-dotted side of a die -- a side important in several winning combinations in dice games. Perhaps because the four spots on a die can suggest an X, "cater" eventually came to be used dialectically with the meaning "diagonal" or "diagonally." This "cater" was combined with "corner" to form "catercorner."
