Man's man? (7)
This clue is a double definition.
'man's' is the first definition.
'man?' is the second definition.
(Other definitions for douglas that I've seen before include "bloke" , "Manx capital" , "Capital of the Isle of Man" , "See 13" , "place of Man" .)
'mans man?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
This is all the clue.
Can you help me to learn more?
