Scot with a lot (5)
I believe the answer is:
laird
'scot with a lot' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for laird that I've seen before include "One's landed in Scotland" , "He's landed in Scotland" , "rich Scotsman" , "Scot. landowner" , "Big landowner" .)
