Respect rocking Rod! (7)
I believe the answer is:
sceptre
'rod' is the definition.
(I have seen 'Rod of office ' mean 'sceptre' so perhaps 'rod' could also mean 'sceptre')
'respect rocking' is the wordplay.
'rocking' indicates an anagram.
'respect' anagrammed gives 'SCEPTRE'.
(Other definitions for sceptre that I've seen before include "Royal staff (paired with 2 down)" , "Staff carried by monarch" , "Staff of regency" , "Official staff" , "Ruler's staff" .)
