Strangely genial Conservative perfectly sweet (7)
I believe the answer is:
angelic
'perfectly sweet' is the definition.
'angelic' can be an answer for 'sweet' (synonyms). I am unsure of the 'perfectly' bit.
'strangely genial conservative' is the wordplay.
'strangely' is an anagram indicator.
'conservative' becomes 'c' (UK political abbreviation).
'genial' is an anagram of 'angeli'.
'angeli'+'c'='ANGELIC'
Can you help me to learn more?
(Other definitions for angelic that I've seen before include "sweet-natured too" , "Sweet and well-behaved" , "Nice gal (anag.)" , "Saintly" , "Payment for release" .)
