ampersand
     
         "&" {ASCII} character 38.
     
        Common names: {ITU-T}, {INTERCAL}: ampersand; amper; and.
        Rare: address (from {C}); reference (from C++); bitand;
        background (from {sh}); pretzel; amp.
     
        A common symbol for "and", used as the "address of" operator
        in {C}, the "reference" operator in {C++} and a {bitwise}
        {AND} operator in several programming languages.
     
        {UNIX} {shells} use the character to indicate that a task
        should be run in the {background}.
     
        The ampersand is a ligature (combination) of the cursive
        letters "e" and "t", invented in 63 BC by Marcus Tirus [Tiro?]
        as shorthand for the Latin word for "and", "et".
     
        The word ampersand is a conflation (combination) of "and, per
        se and".  Per se means "by itself", and so the phrase
        translates to "&, standing by itself, means 'and'".  This was
        at the end of the alphabet as it was recited by children in
        old English schools.  The words ran together and were
        associated with "&".  The "ampersand" spelling dates from
        1837.
