"Wuthering Heights" setting (4)
I believe the answer is:
moor
'wuthering heights setting' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for moor that I've seen before include "Tether (a boat)" , "Berth, tie up" , "Heathland" , "Open land - secure a boat - North African" , "Heath - a North African Muslim" .)
