Catch some cod, with a bit of help (3)
I believe the answer is:
cop
'catch' is the definition.
(I've seen this before)
'some cod with a bit of help' is the wordplay.
'some' suggests taking the first letters.
'with' says to put letters next to each other.
'a bit of help' becomes 'op' (I am not sure about this - if you are sure you should believe this answer much more).
The first letter of 'cod' is 'c'.
'c'+'op'='COP'
Can you help me to learn more?
(Other definitions for cop that I've seen before include "Policeman (informal)" , "Police officer (slang)" , "Get" , "Policeman (colloq.)" , "Policeman (sl)" .)
