Trifles in the theatre (5)
I believe the answer is:
plays
'trifles in the theatre' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for plays that I've seen before include "Dramatist's works" , "Dramas" , "Theatrical works" , "Dramatic works" , "Stage works" .)
