Possibly secure and free from danger (6)
I believe the answer is:
rescue
'free from danger' is the definition.
(I've seen this in another clue)
'possibly secure' is the wordplay.
'possibly' indicates anagramming the letters.
'secure' is an anagram of 'RESCUE'.
'and' is the link.
(Other definitions for rescue that I've seen before include "Save from harm" , "Deliver from danger" , "Save from peril" , "Help out of difficulty, save" , "Extricate" .)
