Works at the Met (6)
I believe the answer is:
operas
'works at the met' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for operas that I've seen before include "Tosca and Lucia Di Lammermoor" , "O spare these dramas" , "Stage dramas" , "Dramatic works set to music" , "Dramas set to music" .)
