After love, reap terrible drama (5)
I believe the answer is:
opera
'drama' is the definition.
(I've seen this before)
'after love reap terrible' is the wordplay.
'after' is a charade indicator (letters next to each other).
'love' becomes 'o' (In tennis, 'love' means 'zero').
'terrible' indicates an anagram.
'reap' with letters rearranged gives 'pera'.
'o'+'pera' is 'OPERA'.
(Other definitions for opera that I've seen before include "Eg, Carmen" , "Drama or comedy set to music" , "Lulu, say" , "Musical entertainment" , "La Scala production, perhaps" .)
