Trivium teaches French and English the way language was taught for a thousand years — through the three classical arts. Grammar: the rules of well-formed speech. Logic: the order of valid thought. Rhetoric: the grace of persuasion. Most language apps train you to tap the right answer. Trivium trains you to understand — and then to say something worth hearing. A YEAR OF STUDY Enroll, take a brief placement, and begin exactly where you stand. Your course unfolds over 52 weeks of short chapters across the three pillars, each ending in real practice: a line of writing, a minute spoken aloud. STUDY THAT RESPECTS YOU • Comprehension first — every rule explained before it is drilled • Spaced repetition returns each idea just before you forget it • Spot the fallacy, master figures of speech, untangle double meanings • Write and speak from the first week — the voice leads • British or American English — choose your spelling, pronunciation and Magister at enrollment • The Magister, your AI preceptor, reads your attempts and lifts your lines to their next rung YOUR CIRCLE Invite a friend and walk the same path — each of you earns extra days of full access. Send a kind word when they need one. There are no leaderboards and no rankings in Trivium. Only study. YOUR LEXICON Save words and turns of phrase as you meet them, and return to them whenever you wish. FOR WHOM Students preparing essays and exams. Professionals who want authority on the page and in the room. Learners of French or English who want fluency with depth. Anyone who suspects that language, thought, and persuasion are one art — as the ancients knew. Begin with a free week of full access. After that the study continues free — a new lesson each day, your reviews always open, and the whole Lexicon. Trivium Scholar opens unlimited lessons and the Magister: yearly or monthly.
