Majestic state (8)
I believe the answer is:
victoria
'majestic state' is the definition.
'victoria' can be an answer for 'state' (Victoria is an example). I'm unsure of the 'majestic' bit.
'majestic state' is the wordplay.
'majestic' becomes 'victor' (I can't justify this - if you can you should give a lot more credence to this answer).
'state' becomes 'IA'.
'victor'+'ia'='VICTORIA'
Can you help me to learn more?
(Other definitions for victoria that I've seen before include "English queen" , "Station - plum - sponge - queen" , "Queenly" , "Queen and Falls" , "place where one may be stationed?" .)
