Spider on the snooker table? (4)
I believe the answer is:
rest
'spider' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'on the snooker table?' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'the snooker table?' becomes 'st' (this might be a standard abbreviation I've not previously seen).
're'+'st'='REST'
Can you help me to learn more?
(Other definitions for rest that I've seen before include "Pole in Crucible?" , "What's left over" , "Motionlessness" , "Leisure" , "Holiday" .)
