Having butterflies fluttering over sun? (7)
I believe the answer is:
nervous
'having butterflies' is the definition.
I can't tell whether this defines the answer.
'fluttering over sun?' is the wordplay.
'fluttering' indicates anagramming the letters.
'over'+'sun'='oversun'
'oversun' anagrammed gives 'NERVOUS'.
Can you help me to learn more?
(Other definitions for nervous that I've seen before include "Frightened" , "full of trepidation" , "'Apprehensive, uneasy (7)'" , "Twitchy" , "Easily agitated, timid" .)
