It has its association with kicks (6)
I believe the answer is:
soccer
'it has its association with kicks' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for soccer that I've seen before include "American football?" , "Ball game" , "Association football" , "Informally, game" , "The beautiful game?" .)
