Etymology

The word fox comes from Old English and derives from Proto-Germanic * fuhsaz. This in turn derives from Proto-Indo-European * puḱ- "thick-haired, tail." Male foxes are known as dogs, tods, or reynards; females as vixens; and young as cubs, pups, or kits, though the last term is not to be confused with the kit fox, a distinct species. "Vixen" is one of very few modern English words that retain the Middle English southern dialectal "v" pronunciation instead of "f"; i.e., northern English "fox" versus southern English "vox". A group of foxes is referred to as a skulk, leash, or earth.
