Means of escape, a cure, path that’s unusual? (9)
I believe the answer is:
parachute
'means of escape' is the definition.
(a parachute can be used to escape)
'a cure path that's unusual?' is the wordplay.
'that's unusual?' indicates an anagram (I've seen 'unusual' mean this).
'a'+'cure'+'path'='acurepath'
'acurepath' with letters rearranged gives 'PARACHUTE'.
(Other definitions for parachute that I've seen before include "canopy" , "Equipment to break a fall from the sky" , "Devise for making descent from an airplane" , "Drop from plane" , "It breaks a fall from the sky" .)
