Everybody informed? Completely? (3,4)
I believe the answer is:
all told
'completely?' is the definition.
Both the definition and answer are adverbs. Perhaps you can see a link between them that I don't see?
'everybody informed?' is the wordplay.
'everybody' becomes 'all' (I've seen this before).
'informed?' becomes 'told' (telling is a kind of informing).
'all'+'told'='ALL TOLD'
Can you help me to learn more?
(Other definitions for all told that I've seen before include "In total" , "To summarise" , "Taking everything into account" , "Everyone informed" , "Taking every one into account" .)
