One with purse covered in gold, returned in perfect state (6)
I believe the answer is:
utopia
'perfect state' is the definition.
(I've seen this in another clue)
'one with purse covered in gold returned' is the wordplay.
'one with' becomes 'i' (I can't explain this - if you can you should give a lot more credence to this answer).
'purse' becomes 'pot' (both can mean a fund).
'covered in' means one lot of letters goes inside another.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'returned' shows that the letters should be reversed in order.
'i'+'pot'='ipot'
'ipot' inserted into 'au' is 'aipotu'.
'aipotu' written backwards gives 'UTOPIA'.
'in' is the link.
Can you help me to learn more?
(Other definitions for utopia that I've seen before include "Ideal country" , "Imagined state of perfection" , "Bliss; paradise" , "place of bliss" , "Place of perfect happiness" .)
