Origin

disputed origin

From back + forty, meaning “back side of a farm”. In the Homestead Acts (1860s–), farmers were granted a quarter section; a section was nominally 1 square mile containing 640 acres, a quarter section was 160 acres, and the quarter section was itself subdivided into four quarter-quarter sections of 40 acres each: two front forty and two back forty. Compare north forty, back of beyond, backcountry, and backwater.

Examples
SIMPLE

CONTEXTUAL

We rarely visit the back forty of the property because the weeds are too tall.

COMPLEX
