Emblem; sign (6)
I believe the answer is:
symbol
I believe this is a double definition.
'emblem' is the first definition.
(I've seen this before)
'sign' is the second definition.
(symbol is a kind of sign)
(Other definitions for symbol that I've seen before include "Meaningful mark" , "Something representative" , "Sign - representation" , "Mark or sign with special meaning" , "Representative mark" .)
