Tells them to cut cents out of credit notes for a change (6)
I believe the answer is:
editor
'tells them to cut' is the definition.
I can't tell whether this definition defines the answer.
'cents out of credit notes for a change' is the wordplay.
'out of' suggests deleting specific letters.
'for a change' is an anagram indicator.
'credit'+'notes'='creditnotes'
'creditnotes' with 'cents' removed is 'rdiote'.
'rdiote' is an anagram of 'EDITOR'.
Can you help me to learn more?
(Other definitions for editor that I've seen before include "Press fellow" , "Reviewer of text" , "Journalist in charge of publication" , "Script-preparer" , "One who orders copy" .)
