Does he show degrees of sportsmanship? (6)
I believe the answer is:
angler
'does he show degrees of sportsmanship?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'does he show' is the wordplay.
I cannot really understand how this works, but
'show' could be 'er' (US medical drama) and 'er' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for angler that I've seen before include "He fishes with rod and line" , "who looks for compliments" , "I may do casting" , "Hook and line fisherman" , "Strait; -- of Lochalsh" .)
