vestigial

Etymology

It is formed from English vestige + -al.^[2] The OED, Merriam-Webster Unabridged, Barnhart and Dictionary.com take the base directly as Latin vestīgium (“footprint, trace”),^[3][4][5][6] the source of the English noun through French,^[7][5] and the Shorter Oxford writes the suffix as -ial.^[8] The further origin of the Latin noun is uncertain.^[7][5] De Vaan finds a link with vestis (“clothes”) senseless, and thinks an older *verstīgium attractive, connected with verrō (“to sweep”), so that the word may first have meant a track or furrow.^[9]

Earliest recorded meaning

Of or like a vestige, a mere trace of what has been, originally in biology: 1850 in Etymonline.^[2] The OED and Barnhart give 1877, in the 8th edition of Gray's Anatomy, of certain organs or structures,^[3][5] and Dictionary.com 1880–85.^[6]

Semantic evolution

The word arose in biology, close to the time when the noun vestige, in use for a mark or trace since about 1600, came to mean a vestigial organ or tissue, by 1859.^[2] It kept this technical use for an organ or part that has grown degenerate or lost its function in the course of evolution.^[8][10] From 1892 it was also used generally, of anything surviving as a faint remnant,^[3] as in "a vestigial flicker of anger", quoted by the Shorter Oxford from the Atlantic.^[8] The vestigial side band, one partly attenuated before transmission, is recorded from 1940.^[3][8]
