Monk withdrawing just so rite can change (10)
I believe the answer is:
cistercian
'monk' is the definition.
(I know that Cistercian is a type of monk)
'withdrawing just so rite can change' is the wordplay.
'withdrawing' shows that the letters should be reversed in order.
'just so' becomes 'sic' ('so' in Latin. I am not sure about the 'just' bit.).
'change' indicates anagramming the letters.
'sic' reversed gives 'cis'.
'rite'+'can'='ritecan'
'ritecan' anagrammed gives 'tercian'.
'cis'+'tercian'='CISTERCIAN'
Can you help me to learn more?
(Other definitions for cistercian that I've seen before include "Man following order" , "Monk" .)
