Settings are parts of the act (6)
I believe the answer is:
scenes
This clue could be a double definition.
'settings' is the first definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'parts of the act' is the second definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe there's a link between them I don't understand?
'are' is the link.
Can you help me to learn more?
(Other definitions for scenes that I've seen before include "Subdivisions of a drama" , "Landscapes" , "Excerpts from a film - or aggressive outbursts" , "Vistas, settings" , "Stage settings" .)
