Winged creature, vaguely clear, about to hover (9)
I believe the answer is:
'winged creature' 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?
'vaguely clear about to hover' is the wordplay.
'vaguely' is an anagram indicator.
'about' indicates putting letters inside.
'to hover' becomes 'hang' (I've seen this in another clue).
'clear' anagrammed gives 'arcel'.
'arcel' enclosing 'hang' is 'ARCHANGEL'.
Can you help me to learn more?
(Other definitions for archangel that I've seen before include "Russian city", "Among others, Michael", "one coming from above with message maybe", "What we call a port", "foreign port".)
