Trace exit in order to set free (9)
I believe the answer is:
extricate
'set free' is the definition.
(I've seen this before)
'trace exit in order' is the wordplay.
'in order' is an anagram indicator (the letters in a new order).
'trace'+'exit'='traceexit'
'traceexit' is an anagram of 'EXTRICATE'.
'to' acts as a link.
(Other definitions for extricate that I've seen before include "Free from entanglement" , "Disentangle, set free" , "Free from entanglements" , "wriggle free" , "Free (someone) from difficulty" .)
