Spell word for academic session (4)
I believe the answer is:
term
I believe this clue is a triple definition!
'spell' is the first definition.
(term can mean a spell or period)
'word' is the second definition.
(term is a kind of word)
'for' is a link.
'academic session' is the third definition.
(I've seen this in another clue)
(Other definitions for term that I've seen before include "Period of school life" , "Word or expression for some particular thing" , "Fixed period of time" , "Scholastic period" , "Division of the school year" .)
