Doctor respects symbols of power (8)

I believe the answer is:

sceptres

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

'symbols of power' is the definition.
'sceptres' can be an answer for 'symbols' (sceptre is a kind of symbol). I am not sure about the 'of power' bit.

'doctor respects' is the wordplay.
'doctor' indicates an anagram.
'respects' is an anagram of 'SCEPTRES'.

Can you help me to learn more?

(Other definitions for sceptres that I've seen before include "Ceremonial or emblematic staffs" , "Offer respects to crowns" , "Insignia of royalty" , "Batons borne by kings" , "'Ceremonial staffs, of royalty, say (8)'" .)

I've seen this clue in The Hindu.
