Carry mark — symbol (5)
I believe the answer is:
totem
'symbol' is the definition.
(thesaurus)
'carry mark' is the wordplay.
'carry' becomes 'tote' (toting is a kind of carrying**).
'mark' becomes 'm'.
'tote'+'m'='TOTEM'
(Other definitions for totem that I've seen before include "Object believed to have spiritual significance" , "Spiritually significant emblem" , "Image representing tribe" , "Natural thing adopted as an emblem" , "Motet (anag.)" .)
