Cross with a loop on the top that often appears in Egyptian personal names (4)
I believe the answer is:
ankh
(Other definitions for ankh that I've seen before include "Ancient Egyptian symbol of life - khan (anag)" , "Hank (anag) - cross symbolising eternal life" , "Ansate cross" , "Egyptian hieroglyph representing life" , "Cross with a loop at the top, symbol of life in ancient Egypt" .)
