(A). A solitary man; the only inhabitant of a place. The tale of Defoe is well known, which describes Robinson Crusoe as cast on a desert island, where he employs the most admirable ingenuity in providing for his daily wants.
Whence creeping forth, to Duty's call he yields, And strolls the Crusoe of the lonely fields.
Bloomfield: Farmer's Boy.
