From *back* + *forty*, the term originated in the American 1860s following the passage of the Homestead Acts. Under these statutes, settlers were granted a quarter section of land. As a standard section was nominally one square mile containing 640 acres, a quarter section comprised 160 acres. This allotment was further partitioned into four quarter-quarter sections of 40 acres each.

The division of the 160-acre homestead created two front forty-acre plots and two back forty-acre plots. The latter term designated the most remote portion of the farm, situated furthest from the main buildings and the public road. The expression remains a linguistic relative of *north forty*, *backcountry*, and *backwater*.
