Arrange to get rid of (7)
I believe the answer is:
dispose
I believe this is a double definition.
'arrange' is the first definition.
(I've seen this before)
'get rid of' is the second definition.
(I've seen this in another clue)
'to' acts as a link.
(Other definitions for dispose that I've seen before include "Arrange - to get rid (of)" , "Spies do (anag) - get rid of" , "make an arrangement" , "Incline" , "Arrange (in order)" .)
