'sue' is the definition.
(I've seen this before)

'ordinary language curiously pleasing' is the wordplay.
'ordinary language' becomes 'prose' (I've seen this before).
'curiously pleasing' becomes 'cute' (I can't justify this - if you can you should believe this answer much more).
'prose'+'cute'='PROSECUTE'

Can you help me to learn more?

(Other definitions for prosecute that I've seen before include "Bring before a criminal court" , "Practise" , "Carry out assessment" , "Take legal action" , "Represent the Crown in court" .)

I've seen this clue in The Independent.
