Adjectives -- or pronouns -- will hold back such writing (5)
I believe the answer is:
prose
'writing' is the definition.
(I've seen this in other clues)
'adjectives or pronouns will hold back' is the wordplay.
'hold' indicates a hidden word (I've seen 'holds' mean this).
'back' says the letters should be written in reverse.
'esorp' is hidden within 'adjectives or pronouns will'.
'esorp' in reverse letter order is 'PROSE'.
'such' acts as a link.
(Other definitions for prose that I've seen before include "Literary genre" , "Ropes (anag.)" , "Not poetry" , "Normal written language" , "Non-verse" .)
