Representation of Gates... (5,3)
I believe the answer is:
stage set
'representation of gates' is the definition.
'stage set' can be an answer for 'representation' (stage set is a kind of representation). I'm unsure of the 'of gates' bit.
'representation of gates' is the wordplay.
I cannot quite see how this works, but
'representation' could be 'set' (set is a kind of representation) and 'set' is located in the answer.
an anagram of 'gates' is 'stage' which is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for stage set that I've seen before include "Scenery and furniture" , "Theatre scenery etc" , "dramatic backdrop" , "play ready to start" .)
