Evasion to conduct a competition (9)
I believe the answer is:
runaround
'evasion' is the definition.
(thesaurus)
'conduct a competition' is the wordplay.
'conduct' becomes 'run' (I've seen this in another clue).
'a competition' becomes 'around' (I am not sure about this - if you are sure you should believe this answer much more).
'run'+'around'='RUNAROUND'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for runaround that I've seen before include "deception" , "small car" .)
