At the break of dawn, it can be magic! (4)
I believe the answer is:
wand
'can be magic' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'at the break of dawn it' is the wordplay.
'dawn' can be anagrammed to 'WAND'.
However, I'm not clear how this is indicated.
Can you help me to learn more?
(Other definitions for wand that I've seen before include "Rod of magician or water-diviner" , "Thin rod" , "Magician's rod" , "Sorceror's magic stick" , "spelling aid" .)
