Writer embraced by fat Scottish landowner (5)
I believe the answer is:
laird
'scottish landowner' is the definition.
(I've seen this in another clue)
'writer embraced by fat' is the wordplay.
'writer' becomes 'I' (the person who is writing these clues).
'embraced by' is an insertion indicator.
'fat' becomes 'lard' (lard is a kind of fat).
'i' put into 'lard' is 'LAIRD'.
(Other definitions for laird that I've seen before include "Scots landowner" , "He's landed in Scotland" , "Big landowner" , "Scottish owner of large estate" , "One's landed in Scotland" .)
