Titular changeling has accepted being divine (9)
I believe the answer is:
archangel
'accepted being divine' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'titular changeling has' is the wordplay.
'has' indicates the answer is hidden within the clue.
'ARCHANGEL' can be found hidden inside 'titular changeling'.
Can you help me to learn more?
(Other definitions for archangel that I've seen before include "Highest ranking member of the celestial hierarchy" , "one coming from above with message maybe" , "Divine messenger - Russian port" , "Michael, for example - Russian port" , "The head celestial messenger" .)
