Try a ruse to fix where your taxes go (8)
I believe the answer is:
treasury
'where your taxes go' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'try a ruse to fix' is the wordplay.
'to fix' is an anagram indicator (I've seen 'fixed' mean this).
'try'+'a'+'ruse'='tryaruse'
'tryaruse' is an anagram of 'TREASURY'.
Can you help me to learn more?
(Other definitions for treasury that I've seen before include "Finance ministry" , "British Department of Finance" , "Government finance department" , "Place where great valuables are stored" , "Government financial department" .)
