Shot on the table in sanctuary (6)
I believe the answer is:
safety
'sanctuary' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for safety that I've seen before include "State of security" , "Absence of danger" , "immunity" , "The condition of being protected from danger" , "one finds in numbers" .)
