☞ 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: which I most commonly say, is going out of use, hear most frequently, ery rarely, and 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 vās; Canada usu. and U. S. also vāz; Canada also & U. S. sometimes väz.”
One wit has noted that “a väz is a vāz that costs more than $100.”, suggesting that the former is considered a higher-class pronunciation. [ 1913 Webster + PJC ]
