Respect trained staff in the palace? (7)
I believe the answer is:
sceptre
'staff in the palace?' is the definition.
'sceptre' can be an answer for 'staff' (sceptre is a kind of staff). I am not sure about the 'in the palace?' bit.
'respect trained' is the wordplay.
'trained' indicates anagramming the letters (to train can mean to grow something into a shape).
'respect' with letters rearranged gives 'SCEPTRE'.
Can you help me to learn more?
(Other definitions for sceptre that I've seen before include "Royal baton" , "Royal symbol" , "Part of the royal regalia" , "Respect (anag) -- symbol of ruler's authority" , "Queen's staff" .)
