Settled, secure and free (6)
I believe the answer is:
rescue
'free' is the definition.
(I've seen this in another clue)
'settled secure' is the wordplay.
'settled' indicates anagramming the letters.
'secure' is an anagram of 'RESCUE'.
'and' is the link.
(Other definitions for rescue that I've seen before include "delivery" , "Save - deliver" , "Free someone from trouble" , "Deliver from danger" , "Save from danger or distress" .)
