A bad shot? Wrong! (5)
I believe the answer is:
amiss
'wrong' is the definition.
(synonyms)
'a bad shot?' is the wordplay.
'bad shot?' becomes 'miss' (I can't justify this - if you can you should give a lot more credence to this answer).
'a'+'miss'='AMISS'
Can you help me to learn more?
(Other definitions for amiss that I've seen before include "Wrong (a girl!)" , "Badly - wrong" , "Faulty" , "Wrorg" , "Revealing fault" .)
