In betting, a borderline thing? (5)
I believe the answer is:
hedge
'thing?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'in betting a borderline' is the wordplay.
I cannot quite see how this works, but
'borderline' could be 'edge' (I've seen this in another clue) and 'edge' is located in the answer.
A single letter 'h' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hedge that I've seen before include "sort of fund" , "Avoid making definite statement" , "Bushy boundary" , "Row of linked shrubs" , "Living barrier" .)
