CURE

Rhotic accents of Scotland and Ireland and South-west England typically have [u(:)], with Orkney and Shetland showing [uə]. [uə/ʊə] is also usual over much of non-rhotic Britain, with a tendency to a disyllabic [(ɪ)uwə] in Wales. A comparatively recent innovation in RP for the CURE vowel is [ɔ:], and this is also found in accents characteristic of Northern and West Midland England and, with [o:], in British Creole.

Unlike other accents of the British Isles, where the phenomenon of ‘yod-deletion’  has only limited application, the accent of East Anglia has no [j] before /u:/ after any consonant: this, together with a realization of the CURE vowel as [з:/ə:], results in such homophones as cure/cur.
