Singer Ora (4)
I believe the answer is:
rita
'singer ora' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rita that I've seen before include "The Beatles' lovely girl" , "Lovely -- , meter maid (Beatles)" , "...Hayworth, ...Coolidge, ... ''Educating ...''" , "subject of education" , "-- Hayworth, US film actress" .)
