New Etude in D not prepared for publication (8)
I believe the answer is:
unedited
'new etude in d not prepared for publication' is the definition.
I can't tell whether this definition defines the answer.
'new etude in d' is the wordplay.
'new' indicates anagramming the letters.
'etude'+'in'='etudein'
'etudein' with letters rearranged gives 'unedite'.
'unedite'+'d'='UNEDITED'
Can you help me to learn more?
(Other definitions for unedited that I've seen before include "As written, without correction" , "Never before published" , "unchanged" , "Left as seen" , "as it was first presented?" .)
