One of the three subjects of the trivium—the basic tier of a classical education, itself based on a Roman model—was Latin grammar.

trivium 的三个科目之一——古典教育的基本层次，本身基于罗马模式——是拉丁语法。

All knowledge was once ordered in relation to the seven liberal arts-grammar, rhetoric, and logic, the trivium; arithmetic, geometry, astronomy, and music, the quadrivium.

所有的知识科——语法、修辞学和逻辑学——三项小知识相关联。算术、几何、天学和音乐，四艺。

And if you need a piece of trivia for your next cocktail party: that trivium mentioned in the first paragraph was, indeed, the source of trivia.

如果您在下一次鸡尾酒会上需要一些琐事：第一段中提到的琐事确实是琐事的来源。
