Blanked out as wine took effect (8)
I believe the answer is:
redacted
'blanked out' is the definition.
The answer and definition can be both related to change as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'wine took effect' is the wordplay.
'wine' becomes 'red' (red is a type of wine).
'took effect' becomes 'acted' (I can't justify this - if you can you should believe this answer much more).
'red'+'acted'='REDACTED'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for redacted that I've seen before include "Obscured part of a text for legal or security reasons" , "Like some scripts" , "Edited for publication" , "censored" .)
