Horse and trap showing sign of neglect (6)
I believe the answer is:
cobweb
'sign of neglect' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'horse and trap' is the wordplay.
'horse' becomes 'cob' (type of horse).
'and' says to put letters next to each other.
'trap' becomes 'web' (web is a kind of trap).
'cob'+'web'='COBWEB'
'showing' is the link.
Can you help me to learn more?
(Other definitions for cobweb that I've seen before include "Spider silk" , "An arachnid's mesh" , "Literary fairy" , "Spun trap" , "Spider's lattice-work" .)
