Arrange to command (5)
I believe the answer is:
order
I believe this clue is a triple definition!
'arrange' is the first definition.
(I know that order is a kind of arrange)
'to' is the second definition.
(thesaurus)
'command' is the third definition.
(I know that order is a type of command)
(Other definitions for order that I've seen before include "Annual film award (5)" , "booking" , "Regulation" , "demand" , "pattern" .)
