Murphy, it seems, will take a shot at a duck (6)
I believe the answer is:
potato
'murphy' is the definition.
(I know that murphy can be written as potato)
'it seems will take a shot at a duck' is the wordplay.
'it seems' becomes 'pot' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'will take' indicates putting letters inside.
'a shot' is an anagram indicator.
'a duck' becomes 'o' (resembles zero - 'duck' in cricket).
'at' is an anagram of 'ta'.
'pot' going around 'ta' is 'potat'.
'potat'+'o'='POTATO'
Can you help me to learn more?
(Other definitions for potato that I've seen before include "hard to handle when hot" , "Edible tuber; hole in stocking (colloq.)" , "Inert person" , "Starchy tuber" , "Murphy (informal)" .)
