Ordered, trim and neat for strict disciplinarian (8)
I believe the answer is:
martinet
'strict disciplinarian' is the definition.
(I've seen this before)
'ordered trim and neat' is the wordplay.
'ordered' is an anagram indicator.
'and' is a charade indicator (letters next to each other).
'trim' put after 'neat' is 'neattrim'.
'neattrim' is an anagram of 'MARTINET'.
'for' acts as a link.
(Other definitions for martinet that I've seen before include "Tyrant, one who demands strict obedience" , "General" , "Strict disciplinarian - met train (anag)" , "Person who demands strict obedience" , "Disciplined type" .)
