trivium

Etymology

It is borrowed from Medieval Latin trivium (“grammar, rhetoric and logic”),^[2][3][4][5] recorded in this sense from the 9th century,^[4] a special use of the classical noun for a place where three roads meet, and so a frequented place or public street.^[4][3][6][7] That noun is formed from Latin tri- (“three”) and via (“road, way”),^{[6][2][8][9][10]} the second of which goes back to Proto-Indo-European *wegh-.^[2] The same noun is the source of trivial, through triviālis,^[4][6] and its plural is the source of trivia.^[4][6]

Earliest recorded meaning

The three lower liberal arts of medieval schools, grammar, rhetoric and logic: Merriam-Webster Unabridged dates the word to 1647,^[5] Etymonline has it by 1751,^[4] and the OED and Barnhart give 1804, in Ranken's History of France.^[6][3]

Semantic evolution

The medieval term covered the three arts regarded as the foundation for the other four of the seven liberal arts, arithmetic, geometry, astronomy and music, which made up the quadrivium.^[4][9][10] Merriam-Webster Unabridged notes that it was required of anyone seeking bachelor's status.^[5] The Shorter Oxford labels the word historical in this sense.^[11] In 1870 zoology applied it, with bivium, to the three front ambulacra of an echinoderm.^[6][5] According to Ayto, the idea of lesser subjects led to trivial for "of little importance" in the 16th century,^[10] though Etymonline explains that sense from "public" and so "commonplace", after the crossroads.^[4]
