lustrous

Etymology

It is formed from English luster + -ous,^{[2][3][4][5][6]} and the OED compares Old French lustreux.^[2] The noun luster is from French lustre (“gloss, radiance”),^[3][7] from Italian lustro,^[7][2] a Romance noun from Latin lūstrō (“to light up, illumine”),^[2][7][3] probably from lūx (“light”).^[2][7] Etymonline traces it to a suffixed form of Proto-Indo-European *leuk- (“light, brightness”).^[3]

Earliest recorded meaning

Having a sheen or gloss: in Shakespeare's All's Well That Ends Well, "good sparks and lustrous",^[2][8] dated 1601 in the 1989 edition of the OED and by Merriam-Webster,^[9][4] but before 1616 in the revised OED, which dates it by the Folio of 1623.^[2] The OED's earliest dated record is then figurative, from Francis Bacon in 1605.^[2] Etymonline dates the word to about 1600,^[3] and Dictionary.com to 1595–1605.^[10]

Semantic evolution

From the start the word described both a physical sheen and, figuratively, brilliance of mind or character: Bacon wrote of a "lustrous" imagination.^[2][8] Johnson (1755) defined it as "bright; shining; luminous", quoting both Shakespeare and Bacon.^[8] Etymonline records the sense "giving or shedding light" from 1742.^[3] The figurative use belongs to a wider pattern, from the late 16th century, of describing pride in terms of reflected light.^[11] The derivatives lustrously and lustrousness appear in the 19th century.^[5][9]
