And the rest turned up to cover property case (8)
I believe the answer is:
cassette
'case' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'and the rest turned up to cover property' is the wordplay.
'and the rest' becomes 'etc' (et cetera).
'turned up' says the letters should be written in reverse.
'to cover' means one lot of letters goes inside another.
'property' becomes 'asset' (I've seen this in another clue).
'etc' in reverse letter order is 'cte'.
'cte' enclosing 'asset' is 'CASSETTE'.
Can you help me to learn more?
(Other definitions for cassette that I've seen before include "It may contain film" , "Container that holds a magnetic tape" , "Recorder would accommodate this" , "Music player" , "Case for reel of magnetic tape" .)
