kitty-corner

No, it's got nothing to with cats! It does have everything to do with the French word quatre, or four, though. This wonderful American word is used to talk about the location of things, usually on the street. It's most often used of intersections (where two or more roads come together), which generally have four corners.

It means that something is located diagonally across from something else. For example, the Bank of Spain is kitty-corner from Casa de América on Cibeles Square: the Corte Inglés's Goya store has two buildings, which are kitty-corner from each other at the intersection of Goya, Alcalá, Conde de Peñalver and Narvaez streets.

Alternate forms include catercorner, kitty-cornered, cata-cornered, and cater-cornered.
