Carry mark for clan symbol (5)
I believe the answer is:
totem
'clan symbol' is the definition.
(I've seen this before)
'carry mark' is the wordplay.
'carry' becomes 'tote' (toting is a kind of carrying).
'mark' becomes 'm'.
'tote'+'m'='TOTEM'
'for' is the link.
(Other definitions for totem that I've seen before include "symbolic animal" , "Symbol, emblem" , "Venerated object" , "Sort of pole" , "family emblem" .)
