Vase

The noun 's vase' has different pronunciations in British and American English.

• In British RP, vase rhymes with 'cars' and 'Mars': 'vahz', IPA: /vɑːz/. (An older pronunciation, 'vawse', /vɔːs/, rhyming with 'horse' and 'cause', may still occasionally be heard.)
• In American GA, vase has the vowel of 'late', 'place' and 'lays', /eɪ/. The final sibilant may be either voiced oe unvoiced, so that vase rhymes either with 'case' or 'raise'. Some older verse written in Britain appears to ask for this pronunciation, but this may be a question of eye rhyme. Byron, for example - who enjoyed games with tortured rhymes - wrote in Don Juan:

... and rich with all contrivances which grace

Those gay recesses: - many a precious stone

Sparkled along its roof, and many a vase

Of porcelain held in the fettered flowers.

Byron Don Juan (1823), Canto VI xcvii, 49, cited OED.
