Make secure? (6)
I believe the answer is:
'make secure?' is the definition.
I can't tell whether this defines the answer.
'make secure?' is the wordplay.
'make' indicates an anagram.
'secure' is an anagram of 'RESCUE'.
(Other definitions for rescue that I've seen before include "liberation" , "Pull from danger" , "Save someone from a dangerous situation" , "Extricate" , "Free - recovery" .)
