Make safe and unusually secure (6)
I believe the answer is:
rescue
'make safe' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'unusually secure' is the wordplay.
'unusually' indicates an anagram.
'secure' anagrammed gives 'RESCUE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for rescue that I've seen before include "Get over, on top of" , "Free from danger or captivity" , "Save from harm" , "Being presumptuous" , "delivery" .)
