Wonderful wand bringing light (4)
I believe the answer is:
Here is my best explanation:
'light' is the definition.
(I have seen 'First light' mean 'dawn' so perhaps 'light' could also mean 'dawn')
'wonderful wand' is the wordplay.
'wand' anagrams to 'DAWN'.
Though, I'm not clear how this is indicated.
'bringing' acts as a link.
Can you help me to learn more?
