A girl to rave about (4)
I believe the answer is:
vera
'a girl to rave about' is the definition.
(I've seen this before)
'rave about' is the wordplay.
'about' indicates an anagram.
'rave' is an anagram of 'VERA'.
(Other definitions for vera that I've seen before include "Duckworth, Lynn" , "and 15: Singing Dame" , "__ Lynn, the forces' sweetheart" , "Girl's name (meaning faith or true)" , "A girl to rave about" .)
