Legislature's better current tax cut (7)
I believe the answer is:
capitol
'legislature's' is the definition.
The answer and definition can be both groups as well as being singular nouns.
Maybe there's an association between them I don't understand?
'better current tax cut' is the wordplay.
'better' becomes 'cap' (both can mean to beat somebody else's attempt).
'current' becomes 'I' (physics symbol).
'tax cut' becomes 'tol' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'cap'+'i'+'tol'='CAPITOL'
Can you help me to learn more?
(Other definitions for capitol that I've seen before include "Washington building where USA Congress meets" , "US Senate and House of Representatives building" , "Home of the US Congress" , "government building" , "Seat of US Congress" .)
