- trivia (n.)
- "trivialities, bits of information of little consequence," by 1932, from the title of a popular book by U.S.-born British aphorist Logan Pearsall Smith (1865-1946) first published in 1902 but popularized in 1918 (with "More Trivia" following in 1921 and a collected edition including both in 1933), containing short essays often tied to observation of small things and commonplace moments. Trivia is Latin, plural of trivium "place where three roads meet;" in transferred use, "an open place, a public place." The adjectival form of this, trivialis, meant "public," hence "common, commonplace" (see trivial). The Romans also had trivius dea, the "goddess of three ways," another name for Hecate, perhaps originally in her triple aspect (Selene/Diana/Proserpine), but also as the especial divinity of crossroads (Virgil has "Nocturnisque hecate triviis ululata per urbes"). John Gay took this arbitrarily as the name of a goddess of streets and roads for his mock Georgic "Trivia: Or, the Art of Walking the Streets of London" (1716); Smith writes in his autobiography that he got the title from Gay.
I KNOW too much; I have stuffed too many of the facts of History and Science into my intellectuals. My eyes have grown dim over books; believing in geological periods, cave dwellers, Chinese Dynasties, and the fixed stars has prematurely aged me. ["Trivia," 1918 edition]
Then noted c.1965 as an informal fad game among college students wherein one asked questions about useless bits of information from popular culture ("What was Donald Duck's address?") and others vied to answer first.
Nobody really wins in this game which concentrates on sports, comics and television. Everyone knows that Amos's wife on the "Amos 'n' Andy Show" is Ruby, but who knows that she is from Marietta, Georgia? Trivia players do. They also know the fourth man in the infield of Tinker-to-Evers-to-Chance, the Canadian who shot down Baron Von Richtofen, and can name ten Hardy Boy books. ["Princeton Alumni Weekly," Nov. 9, 1965]
The board game Trivial Pursuit was released 1982 and was a craze in U.S. for several years thereafter.
- trivial (adj.)
- "ordinary" (1580s); "insignificant, trifling" (1590s), from Latin trivialis "common, commonplace, vulgar," literally "of or belonging to the crossroads," from trivium "place where three roads meet," in transferred use, "an open place, a public place," from tri- "three" (see three) + via "road" (see via). The sense connection is "public," hence "common, commonplace."
The earliest use of the word in English was early 15c., a separate borrowing in the academic sense "of the trivium" (the first three liberal arts -- grammar, rhetoric, and logic); from Medieval Latin use of trivialis in the sense "of the first three liberal arts," from trivium, neuter of the Latin adjective trivius "of three roads, of the crossroads." Related: Trivially. For sense evolution to "pertaining to useless information," see trivia.

- Trojan (adj.)

Trojan horse was figurative of ambush-from-within in Roman times (equus Troianus); attested in English from 1570s; the computer virus sense is attested by 1982.
As a noun from mid-14c., "inhabitant of ancient Troy;" in early modern English, the noun could mean "a determined fellow, one who fights or works hard," from the Trojans' long resistance to the Greeks in the Trojan War, but also in 17c., it was a colloquial term for "person of dissolute life, carousing companion."

Sense of "sing in a full, rolling voice" (first attested 1570s) and that of "fish with a moving line" (c.1600) both are extended technical uses from the general sense of "roll, trundle," the former from "sing in the manner of a catch or round," the latter perhaps confused with trail or trawl. Figurative sense of "to lure on as with a moving bait, entice, allure" is from 1560s. Meaning "to cruise in search of sexual encounters" is recorded from 1967, originally in homosexual slang.
- troll (n.1)
- supernatural being in Scandinavian mythology and folklore, 1610s (with an isolated use mid-14c.), from Old Norse troll "giant being not of the human race, evil spirit, monster." Some speculate that it originally meant "creature that walks clumsily," and derives from Proto-Germanic *truzlan, from *truzlanan (see troll (v.)). But it seems to have been a general supernatural word, such as Swedish trolla "to charm, bewitch;" Old Norse trolldomr "witchcraft."
The old sagas tell of the troll-bull, a supernatural being in the form of a bull, as well as boar-trolls. There were troll-maidens, troll-wives, and troll-women; the trollman, a magician or wizard, and the troll-drum, used in Lappish magic rites. The word was popularized in literary English by 19c. antiquarians, but it has been current in the Shetlands and Orkneys since Viking times. The first record of the word in modern English is from a court document from the Shetlands, regarding a certain Catherine, who, among other things, was accused of "airt and pairt of witchcraft and sorcerie, in hanting and seeing the Trollis ryse out of the kyrk yeard of Hildiswick."
Originally conceived as a race of malevolent giants, they have suffered the same fate as the Celtic Danann and by 19c. were regarded by peasants in in Denmark and Sweden as dwarfs and imps supposed to live in caves or under the ground.
They are obliging and neighbourly; freely lending and borrowing, and elsewise keeping up a friendly intercourse with mankind. But they have a sad propensity to thieving, not only stealing provisions, but even women and children. [Thomas Keightley, "The Fairy Mythology," London, 1850]

Sense transferred to "device used to transmit electric current to streetcars, consisting of a trolley wheel which makes contact with the overhead wires" (1888), then "streetcar drawing power by a trolley" (1891), which probably is short for trolley-car, attested from 1889.
- 1610s, "slovenly woman," often with implications of moral looseness, probably from troll (v.) in sense of "roll about, wallow."
