One who argues that a sporting club needs deer around? (7)
I believe the answer is:
debater
'one who argues that a sporting' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'club needs deer around?' is the wordplay.
'club needs' becomes 'bat' (as in sporting equipment. I am not sure about the 'needs' bit.).
'around?' indicates putting letters inside.
'bat' going into 'deer' is 'DEBATER'.
Can you help me to learn more?
(Other definitions for debater that I've seen before include "Speaker in parliament perhaps" , "Wrangler" , "disputatious type" , "Person discussing" , "argumentative person" .)
