Soften edge of snooker table (7)
I believe the answer is:
cushion
'soften' is the definition.
(I know that soften can be written as cushion)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for cushion that I've seen before include "Protect from blow" , "Dampen" , "Large pad" , "Part of a billiard table" , "See 9" .)
