Push violently the wrong way and spoil (3)
I believe the answer is:
mar
'spoil' is the definition.
(I know that spoil can be written as mar)
'push violently the wrong way' is the wordplay.
I cannot really understand how this works, but
'way' could be 'r' (abbreviation for right) and 'r' is present in the answer.
The remaining letters 'ma' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for mar that I've seen before include "Ram into and spoil" , "Make imperfect" , "Ruin" , "Detract from" , "wreck" .)
