Squire’s way right around county (9)
I believe the answer is:
landowner
'squire's' is the definition.
(thesaurus)
'way right around county' is the wordplay.
'way' becomes 'lane' (lane is a kind of way**).
'right' becomes 'r' (common abbreviation).
'around' means one lot of letters goes inside another.
'county' becomes 'down' (County Down in Northern Ireland).
'lane'+'r'='laner'
'laner' enclosing 'down' is 'LANDOWNER'.
(Other definitions for landowner that I've seen before include "Possessor of real estate" , "One possessing estate" , "man of property" , "One with estates" , "One with much property" .)
