Order to get rid of (7)
I believe the answer is:
dispose
This clue is a double definition.
'order' is the first definition.
(thesaurus)
'get rid of' is the second definition.
(thesaurus)
'to' is the link.
(Other definitions for dispose that I've seen before include "Arrange - to get rid (of)" , "Spies do (anag) - get rid of" , "Place in order (as God does)" , "Place in order; bestow" , "make an arrangement" .)
