Proprietor of beastly place near the eastern tip of Scotland!
I believe the answer is:
laird
'proprietor of beastly place' is the definition.
'laird' can be an answer for 'proprietor' (I've seen this before). I am unsure of the 'of beastly place' bit.
'near the eastern tip of scotland' is the wordplay.
'near' says to put letters next to each other.
'the eastern' becomes 'lair' (I am not sure about this - if you are sure you should believe this answer much more).
'tip of' says to take the final letters.
The final letter of 'scotland' is 'd'.
'lair'+'d' is 'LAIRD'.
Can you help me to learn more?
(Other definitions for laird that I've seen before include "Big landowner" , "Estate landowner" , "Scottish estate-owner" , "Scottish squire" , "Man owning land" .)
