Excited roar following gold light in the sky! (6)
I believe the answer is:
aurora
'light in the sky' is the definition.
'aurora' can be an answer for 'light' (thesaurus). I am unsure of the 'in the sky' bit.
'excited roar following gold' is the wordplay.
'excited' indicates anagramming the letters.
'following' means one lot of letters go next to another.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'roar' is an anagram of 'rora'.
'rora' after 'au' is 'AURORA'.
Can you help me to learn more?
(Other definitions for aurora that I've seen before include "Light phenomenon of polar regions" , "Northern or southern lights" , "dawn arrives" , "Dawn, Sleeping Princess" , "Roman goddess of the dawn" .)
