He tries to bring fish to the bank (6)
I believe the answer is:
angler
'he tries to' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'fish to the bank' is the wordplay.
'fish' becomes 'angle' (angle can mean to fish).
'to the bank' becomes 'r' (I can't explain this - if you can you should believe this answer much more).
'angle'+'r'='ANGLER'
'bring' is the link.
Can you help me to learn more?
(Other definitions for angler that I've seen before include "person hoping to catch fish" , "Sportsman" , "I may do casting" , "Fisher with hook and line." , "Walton's was Compleat" .)
