Sue ignoring charming writing (5)
I believe the answer is:
prose
'writing' is the definition.
(I've seen this in other clues)
'sue ignoring charming' is the wordplay.
'sue' becomes 'prosecute' (I've seen this before).
'ignoring' indicates named letters should be taken away.
'charming' becomes 'cute' (I've seen this before).
'prosecute' with 'cute' taken out is 'PROSE'.
(Other definitions for prose that I've seen before include "Normal written language" , "Literary genre" , "Ordinary writing" , "Not poetry" , "Text" .)
