Aid for snooker player as pride’s shattered (6)
I believe the answer is:
spider
'aid for snooker player' is the definition.
(spider is a type of rest in snooker)
'pride's shattered' is the wordplay.
'shattered' is an anagram indicator.
'prides' anagrammed gives 'SPIDER'.
'as' acts as a link.
(Other definitions for spider that I've seen before include "One has eight legs" , "Webster" , "Snooker player's rest; eight-legged creature" , "Rest for a cue (with eight legs?)" , "Insect-eater" .)
