Fishing spot for Scots (4)
I believe the answer is:
loch
'fishing spot for scots' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for loch that I've seen before include "A Scottish lake like Lomond" , "Eg, Ness" , "Body of (Scottish?) water" , "A Scottish lake like Ness" , "Ness or Lomond, for instance" .)
