Egyptian cross (4)
I believe the answer is:
ankh
'egyptian cross' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ankh that I've seen before include "Ansate cross" , "Egyptian hieroglyph representing life" , "Hank (anag) - cross symbolising eternal life" , "Egyptian cross" , "Waylay" .)
