Staff go moving around back of theatre not visible to audience (8)
I believe the answer is:
offstage
'not visible to audience' is the definition.
I can't tell whether this defines the answer.
'staff go moving around back of theatre' is the wordplay.
'moving around' indicates anagramming the letters.
'back of' indicates one should take the final letters.
The last letter of 'theatre' is 'e'.
'staff'+'go'='staffgo'
'staffgo' is an anagram of 'offstag'.
'offstag'+'e'='OFFSTAGE'
Can you help me to learn more?
(Other definitions for offstage that I've seen before include "out of sight of the audience" , "No longer acting" , "Behind-the-scenes" , "Not visible to the audience" , "not visible from house" .)
