Etymology

Origin of tract¹

First recorded in 1350–1400; (in senses referring to extent of space) from Latin tractus “stretch (of space or time), a drawing out,” equivalent to trac-, variant stem of trahere “to draw” + -tus suffix of verbal action; tract ¹ def. 4 is from Medieval Latin tractus, apparently identical with the above, though literal sense unexplained

Origin of tract²

1400–50; late Middle English tracte, apparently shortening of Medieval Latin tractātus tractate

Explanation

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." In addition to referring to areas of land and small booklets, the word tract can describe complicated systems or structures in the body. If you were to unwind your intestine, an important part of your digestive tract, it would not stretch across a large tract of land, but only 25-28 feet — but that's still pretty long! (You probably don't need to read a tract on human anatomy to realize this would be an unhealthy experiment.)
