Ceremony read out? Correct! (5)
I believe the answer is:
right
'correct' is the definition.
('right' can be a synonym of 'correct')
'ceremony read out?' is the wordplay.
'ceremony' becomes 'rite' (rite is a kind of ceremony).
'read out?' shows a homophone (sound like) (I've seen 'read out' mean this).
'rite' sounds like 'RIGHT'.
(Other definitions for right that I've seen before include "Fair or just" , "Privy Councillors are so honourable" , "Morally good; rectify" , "Legal entitlement" , "Just - correct - title" .)
