Brilliant quality of artist, one inspired by art (8)
I believe the answer is:
radiance
'brilliant quality' is the definition.
'radiance' can be an answer for 'quality' (I have seen 'Glowing quality' mean 'radiance' so perhaps 'quality' could also mean 'radiance'). I'm not sure about the 'brilliant' bit.
'artist one inspired by art' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'one' becomes 'i' (Roman numeral).
'inspired by' is an insertion indicator (some letters breathed in or 'inspired' by others).
'art' becomes 'dance' (dance is a kind of art).
'i' going into 'dance' is 'diance'.
'ra'+'diance'='RADIANCE'
'of' is the link.
Can you help me to learn more?
(Other definitions for radiance that I've seen before include "Glow of joy" , "Brilliance of glow" , "Effulgence" , "Luminous state" , "Glow (of good health?)" .)
