Having wings, he rose fluttering (4)
I believe the answer is:
eros
'having wings he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'rose fluttering' is the wordplay.
'fluttering' indicates an anagram.
'rose' is an anagram of 'EROS'.
Can you help me to learn more?
(Other definitions for eros that I've seen before include "In Greek myth, the god of love" , "God of love; life instinct (Freud)" , "Circus boy" , "very centre of London?" , "divinity" .)
