Vowel systems CURE

There is only one clear case of /u:/ preceding /r/. And this is a non-standard case of a word which would more normally belong to the FORCE set.

There are also two possible cases of retention of ME /u:/, i.e. non-shifting of this to a diphthongal reflex. However, as the developments are not clear, and also involve forms which do show a development to a diphthong, we will deal with these cases when we discuss the POWER set.
