Wrong bit used, correct on paper (3-4)
I believe the answer is:
sub-edit
'correct on paper' is the definition.
(sub-editors correct bits of newspapers)
'wrong bit used' is the wordplay.
'wrong' indicates anagramming the letters.
'bit'+'used'='bitused'
'bitused' anagrammed gives 'SUB-EDIT'.
I've seen this clue in The Times.
Want a hint initially instead of a full solution?
