Put in order, men finally put away (6)
I believe the answer is:
neaten
'put in order' is the definition.
(I've seen this in another clue)
'men finally put away' is the wordplay.
'finally' says to take the final letters.
'put away' becomes 'eaten' (I've seen this before).
The last letter of 'men' is 'n'.
'n'+'eaten'='NEATEN'
(Other definitions for neaten that I've seen before include "set in order" , "Make tidy" , "Spruce up" , "Straighten up" , "Groom" .)
