Plant found in hedgerow by bishop leading hike (7)
I believe the answer is:
bramble
'plant found in hedgerow' is the definition.
'bramble' can be an answer for 'plant' (I have seen 'Prickly plant ' mean 'bramble' so perhaps 'plant' could also mean 'bramble'). I am not sure about the 'found in hedgerow' bit.
'bishop leading hike' is the wordplay.
I cannot quite see how this works, but
'bishop' could be 'b' (chess abbreviation) and 'b' is located in the answer.
The remaining letters 'ramble' 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).
'by' acts as a link.
Can you help me to learn more?
(Other definitions for bramble that I've seen before include "Thorny bush" , "Rough, prickly shrub" , "Prickly hazard" , "Briar" , "Gather fruit" .)
