- A tract is a large, open piece of land — like that tract of farmland you bought when you decided your dream in life was to raise llamas. Tract is also a word for a short pamphlet or booklet, like that tract you recently read entitled "The Care and Feeding of Llamas."

- tract (n.1) "area," mid-15c., "period or lapse of time," from Latin tractus "track, course, space, duration," lit, "a drawing out or pulling," from stem of trahere "to pull, draw," from PIE root *tragh- "to draw, drag, move" (source also of Slovenian trag "trace, track," Middle Irish tragud "ebb;" perhaps with a variant form *dhragh-; see drag (v.)). The meaning "stretch of land or water" is first recorded 1550s. Specific U.S. sense of "plot of land for development" is recorded from 1912; tract housing attested from 1953.
