Light makes air dance around (8)
I believe the answer is:
radiance
'light' is the definition.
(I know that radiance is a type of light)
'air dance around' is the wordplay.
'around' indicates an anagram.
'air'+'dance'='airdance'
'airdance' anagrammed gives 'RADIANCE'.
'makes' acts as a link.
(Other definitions for radiance that I've seen before include "This light" , "Luminous state" , "Glow of joy" , "Glow (as of happiness)" , "shine" .)
