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 tract1

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