Religious symbol carried by Khan repeatedly (4)
I believe the answer is:
ankh
'religious symbol' is the definition.
(ancient Egyptian symbol)
'carried by khan repeatedly' is the wordplay.
'khan repeatedly' means two replacements for 'khan'.
'carried by' indicates the answer is hidden within the clue.
'ANKH' is hidden in the letters of 'khan khan'.
(Other definitions for ankh that I've seen before include "Egyptian cross" , "Hank (anag) - cross symbolising eternal life" , "Egyptian hieroglyph representing life" , "Cross with a loop at the top, symbol of life in ancient Egypt" , "Ancient Egyptian symbol of life - khan (anag)" .)
