Rubbish may be shot here (4)
I believe the answer is:
tosh
'rubbish' is the definition.
(both can mean nonsense)
'be shot here' is the wordplay.
'shot' anagrams to 'TOSH'.
However, I'm not clear how the anagram is indicated.
'may' acts as a link.
Can you help me to learn more?
(Other definitions for tosh that I've seen before include "garbage'" , "mate!" , "Pal" , "Cobblers" , "moonshine" .)
