Order change to accommodate clubs (5)
I believe the answer is:
edict
'order' is the definition.
('edict' can be a synonym of 'order')
'change to accommodate clubs' is the wordplay.
'change' becomes 'edit' (editing is a kind of changing**).
'to accommodate' is an insertion indicator.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'edit' going around 'c' is 'EDICT'.
(Other definitions for edict that I've seen before include "Official order" , "Cited (anag) - proclamation" , "Declaration" , "Canon" , "Legally binding proclamation" .)
