Extraordinary feat in outskirts of Surrey gets protection (6)
I believe the answer is:
safety
'protection' is the definition.
(I've seen this before)
'extraordinary feat in outskirts of surrey' is the wordplay.
'extraordinary' is an anagram indicator.
'in' is an insertion indicator.
'outskirts of' means to remove the middle letters.
'surrey' with its middle taken out is 'sy'.
'feat' anagrammed gives 'afet'.
'afet' inserted inside 'sy' is 'SAFETY'.
'gets' is the link.
(Other definitions for safety that I've seen before include "The condition of being free from danger" , "Sort of catch" , "Freedom from danger or harm" , "Protection" , "Type of match or valve" .)
