To go and do wrong can be enjoyable! (4)
I believe the answer is:
good
'be enjoyable' is the definition.
(thesaurus)
'to go and do wrong' is the wordplay.
'and' says to put letters next to each other.
'do wrong' becomes 'od' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'go'+'od'='GOOD'
'can' is the link.
Can you help me to learn more?
(Other definitions for good that I've seen before include "benefit" , "Well done! Health-giving" , "Well-behaved, kind, or virtuous" , "Obedient" , "Having desirable qualities" .)
