Extremely delicate and light (8)
I believe the answer is:
ethereal
'extremely delicate and light' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ethereal that I've seen before include "There in lea - it looks delicate" , "Delicate - airy" , "Ultra-refined" , "Warm approval" , "Having an unreal lightness or delicateness" .)
