Unknown figure is elevated in style of heavenly regions (7)
I believe the answer is:
elysian
'unknown figure is elevated in style of heavenly regions' is the definition.
I can't judge whether this defines the answer.
'unknown figure is elevated in style' is the wordplay.
'unknown figure' becomes 'y' (unknown value in algebra).
'elevated' shows that the letters should be reversed in order (in a down clue, letters go up).
'in' indicates putting letters inside.
'style' becomes 'elan' (synonyms).
'is' written backwards gives 'si'.
'y'+'si'='ysi'
'ysi' inserted inside 'elan' is 'ELYSIAN'.
Can you help me to learn more?
(Other definitions for elysian that I've seen before include "glorious" , "Of abode of the blessed dead in Greek mythology" , "Like paradise" , "Nile, say (anag)" , "Pertaining to divine fields" .)
