Magic turn (5)
I believe the answer is:
spell
I believe this is a double definition.
'magic' is the first definition.
(thesaurus)
'turn' is the second definition.
('spell' can be a synonym of 'turn')
(Other definitions for spell that I've seen before include "Letter by letter, read out" , "Put letters in right order" , "Formula believed to have magical force" , "Magical charm; period" , "Period of time - bewitching utterance" .)
