Namely different people who have not taken orders (6)
I believe the answer is:
laymen
'people who have not taken orders' is the definition.
'laymen' can be an answer for 'people' (layman is a kind of person). I'm not sure about the rest of the definition.
'namely different' is the wordplay.
'different' indicates anagramming the letters.
'namely' with letters rearranged gives 'LAYMEN'.
Can you help me to learn more?
(Other definitions for laymen that I've seen before include "amateurs" , "fellows in congregation" , "People with little expertise" , "Amateur" , "Non-professionals" .)
