Part of a theatre largely reconstructed (7)
I believe the answer is:
gallery
'part of a theatre' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'largely reconstructed' is the wordplay.
'reconstructed' indicates anagramming the letters.
'largely' with letters rearranged gives 'GALLERY'.
Can you help me to learn more?
(Other definitions for gallery that I've seen before include "Theatre area" , "Eg, the Tate" , "Group of spectators" , "Place to display art" , "Long passage" .)
