You and I go in, being more willing to (7)
I believe the answer is:
readier
'more willing to' is the definition.
I can't tell whether this defines the answer.
'you and i go in' is the wordplay.
'you and i' becomes 'rear' (I can't justify this - if you can you should believe this answer much more).
'go' becomes 'die' (synonyms).
'in' means one lot of letters goes inside another.
'rear' enclosing 'die' is 'READIER'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for readier that I've seen before include "More willing" , "More prepared" , "more immediately available" .)
