It has magic associations at the break of dawn (4)
I believe the answer is:
wand
'it has magic associations at the break' is the definition.
The definition suggests a singular noun which matches the answer.
'of dawn' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'dawn' with letters rearranged gives 'WAND'.
Can you help me to learn more?
(Other definitions for wand that I've seen before include "Extremely angry" , "that may be shaken for a spell" , "Fairy's stick" , "spelling aid" , "Rod of magician or water-diviner" .)
