A year’s rent for an old place in Scotland (8)
I believe the answer is:
ayrshire
'old place in scotland' is the definition.
(historic county of Scotland)
'a year's rent for an' is the wordplay.
'a year's' becomes 'yrs' (abbreviation).
'rent' becomes 'hire' (I've seen this before).
'for' means one lot of letters go next to another (I've seen this in other clues).
'an' becomes 'a'.
'yrs'+'hire'='yrshire'
'yrshire' put after 'a' is 'AYRSHIRE'.
(Other definitions for ayrshire that I've seen before include "Former county of Scotland - breed of cattle" , "cow, perhaps" , "part of Scotland" , "Hardy breed of Scottish dairy cattle" , "milk supplier" .)
