Agreed everything was bound to come out (7)
I believe the answer is:
tallied
'agreed' is the definition.
('tally' can be a synonym of 'agree')
'everything was bound to come out' is the wordplay.
I cannot quite understand how this works, but
'everything' could be 'all' (all things) and 'all' is present in the answer.
'bound' could be 'tied' ('tie' can be a synonym of 'bind') and 'tied' is present in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tallied that I've seen before include "Reckoned debt or score" , "Agreed; calculated" , "Matched" , "Corresponded - kept score" , "Agreed, corresponded" .)
