   Syn: {Quaint}, {Odd}, {Antique}.

   Usage: Antique is applied to that which has come down from
          the ancients, or which is made to imitate some ancient
          work of art. Odd implies disharmony, incongruity, or
          unevenness. An odd thing or person is an exception to
          general rules of calculation and procedure, or
          expectation and common experience. In the current use
          of quaint, the two ideas of odd and antique are
          combined, and the word is commonly applied to that
          which is pleasing by reason of both these qualities.
          Thus, we speak of the quaint architecture of many old
          buildings in London; or a quaint expression, uniting
          at once the antique and the fanciful.
