Time to put letters in order (5)
I believe the answer is:
spell
This clue is a double definition.
'time' is the first definition.
(I've seen this before)
'to put letters in order' is the second definition.
(Other definitions for spell that I've seen before include "Letter by letter, read out" , "Give out letters" , "... mean" , "Formula believed to have magical force" , "JP" .)
