So a cricket club has hesitation in playing it (6)
I believe the answer is:
soccer
'playing it' is the definition.
I can't tell whether this definition defines the answer.
'so a cricket club has hesitation' is the wordplay.
'a cricket club' becomes 'cc' (cricketing abbreviation).
'has' means one lot of letters go next to another.
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'so'+'cc'+'er'='SOCCER'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for soccer that I've seen before include "Informally, game" , "... players playing this (colloquially)" , "Roy Keane's game" , "Association football" , "Ball game" .)
