Content of less articulate literary work (5)
I believe the answer is:
essay
'literary work' is the definition.
(I've seen this in another clue)
'content of less articulate' is the wordplay.
'content of' says to take the centre.
'articulate' becomes 'say' (synonyms).
The middle of 'less' is 'es'.
'es'+'say'='ESSAY'
(Other definitions for essay that I've seen before include "Attempt - piece of writing" , "Try; a piece of writing" , "Endeavour" , "Trial, piece of writing" , "Old experiment" .)
