I comply with new structure of games (7)
I believe the answer is:
olympic
'of games' is the definition.
(Olympic can mean relating to the Olympic Games)
'i comply with new structure' is the wordplay.
'i comply' anagrams to 'OLYMPIC'.
However, I am not clear how this is indicated.
Can you help me to learn more?
(Other definitions for olympic that I've seen before include "re situation in Greece" , "of certain events" , "Of Summer or Winter games" , "Of ancient Greek site (of original games)" , "of champion" .)
