virgule
     
         Rare, and ambiguous: {slash} or {comma}.
     
        "Virgule" (or rather, Latin "virgula", meaning "little rod"
        or, vividly enough, "little penis") was the name of a
        punctuation character shaped like a small {slash} and used in
        the Latin writing system much like a modern {comma} -- hence
        the ambiguity of this term in modern English.
     
        Compare French "virgule" and Italian "virgola", meaning
        "comma" (not "slash"); Italian "doppia virgola" and
        "virgoletta", both meaning "{double quote}".
