Bound to include everyone in league (7)
I believe the answer is:
tallied
'bound to include everyone in league' is the definition.
I can't judge whether this defines the answer.
'bound to include everyone' is the wordplay.
'bound' becomes 'tied' (similar in meaning).
'to include' is an insertion indicator.
'everyone' becomes 'all' (all people).
'tied' enclosing 'all' is 'TALLIED'.
Can you help me to learn more?
(Other definitions for tallied that I've seen before include "Corresponded - kept score" , "Agreed, corresponded" , "Matched" , "Agreed; calculated" , "Reckoned debt or score" .)
