Eastern money consumed for legislative body (6)
I believe the answer is:
senate
'for legislative body' is the definition.
(I've seen this before)
'eastern money consumed' is the wordplay.
'eastern' shows that the letters should be reversed in order (letters written right to left or east to west).
'money' becomes 'nes' (I can't justify this - if you can you should give a lot more credence to this answer).
'consumed' becomes 'ate' (to eat is to consume food).
'nes' backwards is 'sen'.
'sen'+'ate'='SENATE'
Can you help me to learn more?
(Other definitions for senate that I've seen before include "Legislative assembly" , "Upper council of university" , "Roman state council" , "Upper assembly of US" , "The upper house in parliament or oireachtas" .)
