Magic period? (5)
I believe the answer is:
spell
I believe this is a double definition.
'magic' is the first definition.
(thesaurus)
'period?' is the second definition.
(spell can mean a period of time)
(Other definitions for spell that I've seen before include "Name letters of a word" , "Give out letters" , "Name in order the letters of the alphabet involved" , "Trance" , "Short time, splinter" .)
