Student of wizardry, snooker player? (6)
I believe the answer is:
potter
'snooker player?' is the definition.
(pots balls)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for potter that I've seen before include "Wizard Harry" , "eg Harry or Beatrix" , "Creator of ceramics" , "Dabble; dawdle" , "One who works with clay" .)
