        <p>The word <strong>ampersand</strong> is a corruption of the phrase "and per se & (and)", meaning "and intrinsically the word and (represented by the symbol &)".</p>
      <p>The ampersand can be traced back to the 1st century A.D. and the Old Roman cursive, in which the letters E and T occasionally were written together to form a ligature.</p>
