Would one have journos re-do it potentially? (6)
I believe the answer is:
editor
'would one have journos' is the definition.
I can't judge whether this definition defines the answer.
're-do it potentially?' is the wordplay.
'potentially?' indicates anagramming the letters (letters have the potential to spell a new word).
're'+'do'+'it'='redoit'
'redoit' with letters rearranged gives 'EDITOR'.
Can you help me to learn more?
(Other definitions for editor that I've seen before include "Person who revises and prepares for publication" , "One who revises another's writing" , "Reviser" , "Newspaperman" , "cutter?" .)
