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'm not certain of the 'in the palace?' bit.
'respect trained' is the wordplay.
'trained' is an anagram indicator (train can mean to shape or manipulate).
'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" .)
