Account of proposed law
I believe the answer is:
bill
This might be a double definition.
'account' is the first definition.
(synonyms)
'proposed law' is the second definition.
'bill' can be an answer for 'law' (thesaurus). I'm unsure of the 'proposed' bit.
'of' is the link.
Can you help me to learn more?
(Other definitions for bill that I've seen before include "Projecting mouth of a bird" , "Banknote; beak" , "informing of damage" , "amount owed" , "The fellow" .)
