Denounce editor's review before Blanchett (9)
I believe the answer is:
deprecate
'denounce' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'editor's review before blanchett' is the wordplay.
'editor' becomes 'ed' (abbreviation).
'review' says the letters should be written in reverse.
'before' becomes 'pre' (prefix meaning 'before').
'blanchett' becomes 'cate' (I can't explain this - if you can you should give a lot more credence to this answer).
'ed' back-to-front is 'de'.
'de'+'pre'+'cate'='DEPRECATE'
Can you help me to learn more?
(Other definitions for deprecate that I've seen before include "Deplore; disparage" , "Express strong disapproval of" , "Disapprove of" , "Deplore or belittle" , "Feel and express disapproval of" .)
