Copper attending disturbance overlooking last odd item (5)
I believe the answer is:
curio
'odd item' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'copper attending disturbance overlooking last' is the wordplay.
'copper' becomes 'cu' (chemical symbol).
'attending' is a charade indicator (letters next to each other).
'disturbance' becomes 'riot' (I've seen this in another clue).
'overlooking last' means to remove the last letter.
'riot' with its final letter taken away is 'rio'.
'cu'+'rio'='CURIO'
Can you help me to learn more?
(Other definitions for curio that I've seen before include "Rare and unusual item" , "Something unusual, perhaps worthy of collecting" , "(Unusual) collector's item" , "Antique" , "Object that is interesting, being rare or unusual" .)
