Emblem of royalty (7)
I believe the answer is:
sceptre
'emblem of royalty' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sceptre that I've seen before include "Royal staff (paired with 2 down)" , "Official staff" , "Staff carried by monarch" , "Royal baton" , "Queen's staff" .)
