Outlined more clearly, like entries in new OED, ... (9)
I believe the answer is:
redefined
'outlined more clearly like entries' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'in new oed' is the wordplay.
I cannot quite understand how this works, but
'in' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for redefined that I've seen before include "Given a new explanation" , "specified differently" , "Again determined" .)
