Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you enter them into the search window. If a compound term doesn’t appear in the drop-down list, try entering the term into the search window and then hit the search button (instead of the “enter” key).

[Middle English trivialle, of the trivium (from Medieval Latin triviālis, from trivium, trivium; see TRIVIUM) and Latin triviālis, ordinary (from trivium, crossroads).]

trivi·al·ly adv.

Synonyms: trivial, trifling, paltry, petty, picayune
These adjectives all apply to what is unimportant and of little consequence. Trivial and trifling refer to what is so insignificant as to be utterly commonplace or unremarkable: "Both sides appreciated that behind this apparently trivial matter of naval salutes lay weighty issues of sovereignty at sea" (Simon Schama). "Now he was smitten with compunction, yet irritated that so trifling an omission should be stored up against him after nearly two years of marriage" (Edith Wharton).
Paltry describes what falls so far short of what is required or desired that it arouses contempt: "The mere fact of grave issues in life depending on such paltry things is monstrously ludicrous" (George Gissing).
Petty usually refers to what is of minor or lesser significance: "Religious slurs, temper tantrums, insults, coercion, debt: all petty things, really, irritantstoo minor, it would seem, to move five reasonable people to murder" (Donna Tartt).
What is picayune is of negligible value or importance: "Everything was numbers-orientedbetter to close out thirty-five picayune cases than go after two quality ones" (Selwyn Raab).

Word History: The word trivial entered Middle English with senses quite different from its most common contemporary ones. We find in a work from 1432-50 mention of the "arte trivialle," an allusion to the three liberal arts that made up the trivium, the lower division of the seven liberal arts taught in medieval universitiesgrammar, rhetoric, and logic. The history of trivial goes back to the Latin word trivium, formed from the prefix tri-, "three," and via, "road." Trivium thus meant "the meeting place of three roads, especially as a place of public resort." The publicness of such a place also gave the word a pejorative sense that we express in the phrase the gutter, as in "His manners were formed in the gutter." The Latin adjective triviālis, derived from trivium, thus meant "appropriate to the street corner, commonplace, vulgar." Trivial is first recorded in English with a sense identical to that of triviālis in 1589. Shortly after that trivial is recorded in the sense most familiar to us, "of little importance or significance," making it a word now used of things less weighty than grammar, rhetoric, and logic.
