regress

Etymology

The noun is borrowed from Anglo-Norman regresse or Middle French regres,^[1] with their source Latin regressus (“a return, retreat, going back”).^{[1][2][3][4][5]} Compare Spanish regreso, Portuguese regresso and Italian regresso.^[1] The Latin noun is from the past participle of regredior (“to go back”),^[1][2][3][4] formed from re- (“back”) and gradior (“to step, walk”),^[2][3][4][6] from Proto-Indo-European *ghredh- (“to walk, go”).^[2][6] The English verb comes directly from the past-participial stem of that Latin verb;^[1][7] French régresser is not recorded until 1878.^[1] Its psychological sense follows German regredieren, first recorded in that sense in 1912 or earlier.^[1]

Earliest recorded meaning

A right in law, to return to the possession of land or property, chiefly in Scots law: 1444.^[1] Barnhart dates the noun about 1375 in the sense "a going back, return",^[3] and Etymonline to the late 14th century,^[2] but the Middle English Dictionary's only record is of 1477,^[8] and the revised OED's first example of that sense is of 1478.^[1] The verb is recorded before 1525, in astronomy,^[1] then from 1552 in the general sense of going back.^[1][9][3]

Semantic evolution

The noun was at first largely a legal term,^[1][2] used of the right to re-enter land, of the document recording that right, the letter of regress (1481), of the claim to compensation against someone (1467), and of the right to return to a resigned benefice (1620).^[1] The general sense of going back or coming back appears in 1478, in a parliamentary record,^[1][8] and Johnson (1755) still defined the noun as "passage back; power of passing back".^[10] The notion of going back to an earlier state is older in the noun (before 1522, in G. Douglas's translation of Virgil) than in the verb (1650, in Sir T. Browne).^[1] Logic made the noun a working back in thought from effect to cause (1620),^[1][2] and later a series in which each step needs a further explanation, as in an infinite regress.^[11][7] The verb was applied to the retrograde motion of the moon's nodes before 1525,^[1] which Barnhart and Etymonline first find only in 1823.^[3][2] It was used of diseases and tissues from 1853,^[1] of tending toward an average from 1885, in Galton,^[1] and of a sea withdrawing from the land from 1920.^[1] In 1915, in B. M. Hinkle's translation of Jung, it took on the sense of reverting to an earlier psychological state,^[1] a sense Etymonline dates to 1926.^[2] It became transitive in that field in 1949, to cause someone to do so,^[1][9] and in statistics in 1954, to calculate regression coefficients.^[1][11]
