Dishonour results if many go wrong (6)
I believe the answer is:
infamy
'dishonour results' is the definition.
'infamy' can be an answer for 'dishonour' (I've seen this before). I'm unsure of the 'results' bit.
'if many go wrong' is the wordplay.
'go wrong' indicates an anagram.
'if'+'many'='ifmany'
'ifmany' with letters rearranged gives 'INFAMY'.
Can you help me to learn more?
(Other definitions for infamy that I've seen before include "Disrepute" , "Public disgrace" , "bad report" , "Wicked reputation" , "Villainous act" .)
