One year's hedging right behind spring border (8)
I believe the answer is:
boundary
'border' is the definition.
(I know that border can be written as boundary)
'one year's hedging right behind spring' is the wordplay.
I cannot really understand how this works, but
'one' could be 'un' (northern English dialect form of 'one') and 'un' is located in the answer.
'right' could be 'ar' (I've seen this in other clues) and 'ar' is found within the answer.
'year' could be 'y' and 'y' is found within the answer.
The remaining letters 'bod' is a valid word 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 boundary that I've seen before include "Line marking the outer limits" , "line between states" , "Four, perhaps" , "Line determining the limits of an area" , "Limit (of an area)" .)
