Disentangle from a mangled Crete taxi (9)
I believe the answer is:
extricate
'disentangle' is the definition.
(I know that disentangle can be written as extricate)
'a mangled crete taxi' is the wordplay.
'a mangled' is an anagram indicator.
'crete'+'taxi'='cretetaxi'
'cretetaxi' is an anagram of 'EXTRICATE'.
'from' acts as a link.
(Other definitions for extricate that I've seen before include "wriggle free" , "Disentangle, release from difficulty" , "Free from entanglements" , "Free (something) from difficulty" , "Get free from" .)
