Tragic queen revealing identification amidst celebration (4)
I believe the answer is:
dido
'tragic queen' is the definition.
(I've seen this before)
'identification amidst celebration' is the wordplay.
'identification' becomes 'ID' (abbreviation).
'amidst' indicates putting letters inside (amidst can mean between or within).
'celebration' becomes 'do' (I've seen this in other clues).
'id' going within 'do' is 'DIDO'.
'revealing' is the link.
(Other definitions for dido that I've seen before include "Lover of Aeneas" , "---- and Aeneas, opera by Purcell" , "Queen < singer" , "Former queen of Carthage" , "She loved Aeneas" .)
