Run past, wild and free? (7)
I believe the answer is:
unstrap
'free?' is the definition.
(thesaurus)
'run past wild' is the wordplay.
'wild' indicates an anagram.
'run'+'past'='runpast'
'runpast' is an anagram of 'UNSTRAP'.
'and' is the link.
(Other definitions for unstrap that I've seen before include "Release" , "Remove fastenings from" , "loose" , "Loosen tie" .)
