Member marching in order of age, Norman? Not exactly! (9)
I believe the answer is:
orangeman
'member' is the definition.
(Orangeman is an example)
'age norman? not exactly' is the wordplay.
'not exactly' indicates an anagram.
'age'+'norman'='agenorman'
'agenorman' is an anagram of 'ORANGEMAN'.
'marching in order of' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for orangeman that I've seen before include "one used to marching?" , "Member of a Protestant Irish society" , "Religious society member" , "Northern Ireland Protestant" .)
