Easy to work with second composition (5)
I believe the answer is:
essay
'composition' is the definition.
(I've seen this before)
'easy to work with second' is the wordplay.
'to work with' indicates anagramming the letters (letters worked into a new order).
'second' becomes 's' (common abbreviation).
'easy' mixed up with 's' makes 'ESSAY'.
(Other definitions for essay that I've seen before include "Trial, piece of writing" , "Short literary piece: attempt" , "Test" , "Short treatise" , "Try; short written work" .)
