Singer Suzanne (4)
I believe the answer is:
vega
'singer suzanne' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for vega that I've seen before include "Brightest star of constellation Lyra" , "Fifth brightest star" , "heavenly body" , "Star in Lyra; grassy plain (Spanish)" , "First magnitude star" .)
