Found on a billiard table it may be used for a rest (7)
I believe the answer is:
cushion
'a rest' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'found on a billiard table it may be' is the wordplay.
I cannot really understand how this works, but
'on' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'used for' is the link.
Can you help me to learn more?
(Other definitions for cushion that I've seen before include "See 9" , "absorb shock?" , "Protect from blow" , "Soften (the effect of an impact)" , "Padded pillow" .)
