   Note: Until the time of Walker (1791), vase was made to rhyme
         with base, case, etc., and it is still commonly so
         pronounced in the United States. Walker made it to
         rhyme with phrase, maze, etc. Of modern English
         practice, Mr. A. J. Ellis (1874) says: "Vase has four
         pronunciations in English: v[add]z, which I most
         commonly say, is going out of use, v[aum]z I hear most
         frequently, v[=a]z very rarely, and v[=a]s I only know
         from Cull's marking. On the analogy of case, however,
         it should be the regular sound."
         The Merriam-Webster's 10th Colletgiate Dictionary says:
         "U. S. oftenest v[=a]s; Canada usu. and U. S. also
         v[=a]z; Canada also & U. S. sometimes v[aum]z."
         One wit has noted that "a v[aum]z is a v[=a]z that
         costs more than $100.", suggesting that the former is
         considered a higher-class pronunciation.
         [1913 Webster + PJC]

   3. (Bot.) The calyx of a plant.
      [1913 Webster]
