Close of play (8)
I believe the answer is:
epilogue
This could be a double definition.
'close' is the first definition.
(I know that epilogue is a type of close)
'play' is the second definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'of' is the link.
Can you help me to learn more?
(Other definitions for epilogue that I've seen before include "Short postscript" , "Short concluding section in literary work" , "Concluding part" , "Final part of book" , "End-of-play speech" .)
