Somewhat changed it? Ordinarily that’s my job! (6)
I believe the answer is:
editor
'my job' is the definition.
I can't judge whether this defines the answer.
'somewhat changed it? ordinarily' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'EDITOR' can be found hidden inside 'changed it ordinarily'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for editor that I've seen before include "Someone in the rag trade" , "One expected to make final" , "Person in charge of paper" , "Senior journalist" , "Rag worker" .)
