Tragic queen made love (4)
I believe the answer is:
dido
'tragic queen' is the definition.
(I've seen this before)
'made love' is the wordplay.
'made' becomes 'did' ('do' can be a synonym of 'make').
'love' becomes 'o' (love means zero in tennis).
'did'+'o'='DIDO'
(Other definitions for dido that I've seen before include "Ancient queen of Carthage" , "Tyre lady" , "Founding queen of Carthage (did next to nothing!)" , "Operatic heroine" , "Lover of Aeneas" .)
