He represents a male following (5)
I believe the answer is:
agent
'he represents' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'a male following' is the wordplay.
'male' becomes 'gent' (gent is a kind of male).
'following' is a charade indicator (letters next to each other).
'a'+'gent'='AGENT'
Can you help me to learn more?
(Other definitions for agent that I've seen before include "One may be working" , "Middleman" , "Spy; representative" , "Person who does business on behalf of another" , "One does business on behalf of another" .)
