With care regularly correcting text acknowledging person's role (9)
I believe the answer is:
crediting
'text acknowledging person's role' is the definition.
I can't tell whether this defines the answer.
'with care regularly correcting' is the wordplay.
'with' says to put letters next to each other.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'correcting' becomes 'editing' (I am not sure about this - if you are sure you should believe this answer much more).
The alternate letters of 'care' are 'cr'.
'cr' next to 'editing' is 'CREDITING'.
Can you help me to learn more?
(Another definition for crediting that I've seen is " Believing or trusting".)
