Copper abandoned remote obsession (8)
I believe the answer is:
farthing
'copper abandoned remote obsession' is the definition.
The answer and definition can be both related to property as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'remote obsession' is the wordplay.
'remote' becomes 'far' (synonyms).
'obsession' becomes 'thing' (I've seen this before).
'far'+'thing'='FARTHING'
Can you help me to learn more?
(Other definitions for farthing that I've seen before include "Old British coin" , "Obsolete small coin" , "It used to be one quarter of a penny" , "Former British coin" , "Old piece" .)
