Raised concerns about setter emulating a heavenly being (8)
I believe the answer is:
seraphic
'emulating a heavenly being' is the definition.
I can't tell whether this definition defines the answer.
'raised concerns about setter' is the wordplay.
'raised' shows that the letters should be reversed in order (going up in a down clue).
'concerns' becomes 'cares' ('care' can be a synonym of 'concern').
'about' means one lot of letters goes inside another.
'setter' becomes 'Phi' (Independent crossword setter).
'cares' back-to-front is 'serac'.
'serac' placed around 'phi' is 'SERAPHIC'.
Can you help me to learn more?
(Other definitions for seraphic that I've seen before include "serene" , "To do with top angels" , "Angelic" , "Like the highest ofder of angels" .)
