tractable

Etymology

It is borrowed from Latin tractābilis (“that may be touched or handled; manageable, compliant”),^{[2][3][4][5][6][7]} from tractō (“to handle, manage”),^[2][3][4][8] the frequentative of trahō (“to draw, drag”),^[6][7][9] with the suffix -bilis.^[2][5] The Latin verb is also the source of treat.^[3][4][7] The OED compares the earlier treatable, from French,^[2][10] which Klein calls a doublet of tractable,^[9] and compares the Anglo-Norman and Middle French variants tractable and traictable of traitable, which the English spelling traictable probably follows.^[2]

Earliest recorded meaning

In a Middle English translation of Guy de Chauliac's Grande Chirurgie, from about 1425,^[4][2][11] where the parts in the middle of the belly are said to be more tractable than the sides: the Middle English Dictionary reads it as an anatomical term, "capable of contracting",^[11][7][3] while the revised OED (2026) takes it as "easy to handle, pliant".^[2]

Semantic evolution

The common modern sense, used of people and animals, "easy to control or influence, docile", is recorded from about 1504, in a translation of Thomas à Kempis,^[2][5] and "easily persuaded to" from 1509.^[2] Etymonline dates the word to the early 15th century and the sense "easy to deal with", of things and situations, to the 1550s.^[3] Two literal senses, "that can be touched or felt" and "that can be endured", appear in 1605 and died out in the 1690s;^[2] Etymonline notes that the literal Latin sense never became established in English.^[3] Johnson (1755) defined it as manageable, docile, compliant and governable.^[12] From the 18th century it was used in mathematics of expressions easy to manipulate or solve (before 1739), and in the 20th century of what is feasible or practical (1937).^[2] In Cheshire dialect it meant teachable.^[13]
