Everyone at home is very tired (3,2)
I believe the answer is:
all in
'very tired' is the definition.
'all in' can be an answer for 'tired' (similar in meaning). I am not sure about the 'very' bit.
'everyone at home' is the wordplay.
'everyone' becomes 'all' (all people).
'at home' becomes 'in' (similar in meaning).
'all'+'in'='ALL-IN'
'is' is the link.
Can you help me to learn more?
(Other definitions for all in that I've seen before include "Inclusive; tired" , "Jiggered" , "Quite exhausted - everyone at home" , "Pooped" , "Exhausted - with no holds barred (3-2)" .)
