Make free (of) (3)
I believe the answer is:
rid
'make free of' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rid that I've seen before include "Free (someone of something unwanted)" , "Clear, remove" , "Free from something unpleasant" , "Throw off, unburden" , "Free, deliver, clear" .)
