Support phase where actors wait (9)
I believe the answer is:
backstage
'actors wait' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'support phase' is the wordplay.
'support' becomes 'back' (to back is to support or endorse).
'phase' becomes 'stage-' (synonyms).
'back'+'stage'='BACKSTAGE'
'where' is the link.
Can you help me to learn more?
(Other definitions for backstage that I've seen before include "dressing room area" , "Wings etc" , "Behind the scenes (theatrically)" , "out of the limelight" , "away from public view" .)
