Group of monks giving command (5)
I believe the answer is:
order
This clue is a double definition.
'group of monks' is the first definition.
(I've seen this in another clue)
'command' is the second definition.
(I know that order is a type of command)
'giving' acts as a link.
(Other definitions for order that I've seen before include "in which things are properly arranged?" , "Direct or requisition" , "association" , "Decree" , "demand" .)
