Bouncer sent out by club? (4,4)
I believe the answer is:
golf ball
'club?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'bouncer sent out by' is the wordplay.
'bouncer' becomes 'ball' (something that bounces).
'sent out' becomes 'golf' (I am not sure about this - if you are sure you should believe this answer much more).
'by' says to put letters next to each other.
'ball' put after 'golf' is 'GOLF-BALL'.
Can you help me to learn more?
(Other definitions for golf ball that I've seen before include "Object driven by club towards hole" , "It may be hit by putter" , "one must take on one's rounds" , "Pill" , "Links projectile" .)
