Easy to work with school composition (5)
I believe the answer is:
essay
'composition' is the definition.
(I've seen this in another clue)
'easy to work with school' is the wordplay.
'to work with' indicates an anagram (letters worked into a new order).
'school' becomes 'S'.
'easy' with its letters mixed up with 's' makes 'ESSAY'.
(Other definitions for essay that I've seen before include "Make an effort to write one" , "Composition; attempt" , "Short literary piece: attempt" , "Attempt - piece of writing" , "Have a shot at a written piece" .)
