sceptre

I'm a little stuck... Click here to teach me more about this clue!

'wand' is the definition.
(I know that wand can be written as sceptre)

'respect for royal' is the wordplay.
'respect' can be anagrammed to 'SCEPTRE'.
But, I am not clear how this is indicated.

Can you help me to learn more?

(Other definitions for sceptre that I've seen before include "Queen's staff" , "Staff of regency" , "Royal baton" , "Royal symbol" , "Rod of office" .)
