Coach employs magic for big sporting occasion (7,5)
I believe the answer is:
olympic games
'big sporting occasion' is the definition.
The answer and definition can be both related to natural events as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'coach employs magic' is the wordplay.
'coach' is an anagram indicator (coach can mean to change or improve).
'employs'+'magic'='employsmagic'
'employsmagic' anagrammed gives 'OLYMPIC GAMES'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for olympic games that I've seen before include "sporting festival" , "Four-yearly event" , "Two thousand and twelve London event" , "Event whose sign here" , "Periodic sporting contests" .)
