Passionate singer uplifted (4)
I believe the answer is:
avid
'passionate' is the definition.
(I've seen this before)
'singer uplifted' is the wordplay.
'singer' becomes 'diva' (diva can mean a female opera singer).
'uplifted' says the letters should be written in reverse.
'diva' written backwards gives 'AVID'.
(Other definitions for avid that I've seen before include "Greedy - enthusiastic" , "Mad for diva" , "Keen and eager" , "Keen, enthusiastic" , "Greedily eager" .)
