He may provide a cup for the snooker player (6)
I believe the answer is:
potter
'snooker player' is the definition.
(pots balls)
'he may provide a cup for the' is the wordplay.
I cannot quite see how this works, but
'cup' could be 'pot' and 'pot' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for potter that I've seen before include "Dabble; dawdle" , "at the wheel?" , "Pootle" , "Mess (around)" , "Creator of ceramics" .)
