It's used in a new form for scholastic work (7)
I believe the answer is:
studies
'a new form for scholastic work' is the definition.
I can't tell whether this defines the answer.
'it's used' is the wordplay.
'it's used' anagrams to 'STUDIES'.
But, I'm not clear how the anagram is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for studies that I've seen before include "Work done to acquire learning" , "Applies the mind to learning" , "Closely inspects; rooms" , "lessons" , "Scrutinises" .)
