State funds misused at Surrey (8)
I believe the answer is:
treasury
'state funds' is the definition.
'treasury' can be an answer for 'funds' (treasury is a kind of funds). I'm not sure about the 'state' bit.
'misused at surrey' is the wordplay.
'misused' is an anagram indicator.
'at'+'surrey'='atsurrey'
'atsurrey' with letters rearranged gives 'TREASURY'.
Can you help me to learn more?
(Other definitions for treasury that I've seen before include "Place where great valuables are stored" , "Finance ministry" , "Bank" , "Its valued contents" , "Repository of government funds" .)
