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 see how this works, but
'everything' could be 'all' (all things) and 'all' is present in the answer.
'bound' could be 'tied' (similar in meaning) and 'tied' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
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" .)
