A man who might be representative (5)
I believe the answer is:
agent
'be representative' is the definition.
(I've seen this before)
'a man' is the wordplay.
'man' becomes 'gent' (gent is a kind of man).
'a'+'gent'='AGENT'
'who might' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for agent that I've seen before include "He or she acts for actors" , "that may be secret?" , "Catalyst" , "Factor, spy" , "factor in Scotland" .)
