Locks guarding entrance to Scottish minister's residence (5)
I believe the answer is:
manse
'minister's residence' is the definition.
(house for a religious minister)
'locks guarding entrance to scottish' is the wordplay.
'locks' becomes 'mane' (I've seen this in other clues).
'guarding' means one lot of letters goes inside another.
'entrance to' indicates taking the first letters.
The initial letter of 'scottish' is 's'.
'mane' placed around 's' is 'MANSE'.
(Other definitions for manse that I've seen before include "Scots minister's house" , "Accommodation" , "church property?" , "Pile of rector'" , "Presbyterian minister's residence" .)
