Declinatio: Latin Grammar
Learn Latin, Read the Aeneid
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Latin endings tell you how words fit together. Declinatio helps you recognize them, put them to use, and read Caesar in the original.
FORM PRACTICE
Practice a noun form, check your answer, and learn how the stem and ending fit together.
SENTENCE COMPLETION
Put Latin cases into context. Complete a Latin sentence with the correct form, using an English translation and an optional hint.
LECTIŌ — READ CAESAR AND NEPOS
Read Caesar's Gallic War and the Lives of Miltiades, Hamilcar and Hannibal by Cornelius Nepos in the original Latin.
Fill in missing Latin words as you read, with form prompts, an English translation and optional hints to help you. Get feedback on each answer, tap any word to see its dictionary entry, meaning and grammatical form, and pick up where you left off in each chapter.
Explore all of Book I of the Gallic War, plus Caesar's landing in Britain (Book IV), Ambiorix's revolt and the siege of Cicero's camp (Book V), and the Gauls and their Druids (Book VI).
VERBA — BUILD YOUR VOCABULARY
Learn 600 common words from Declinatio's Caesar and Nepos readings, ranked by estimated frequency and grouped into decks of 100. The first deck accounts for about half of those texts. Review words at spaced intervals to help them stick.
SENTENTIAE — DAILY SENTENCES
Practice with eight sentences a day, matched to your level, from Caesar, Cicero, Vergil, Catullus, the Vulgate and more. Fill in one missing form in each sentence. When you're ready for longer reading, try the Pōns guided passages: two adapted readings from Eutropius and Nepos that help you work toward Caesar.
SMART REVIEW
Keep what you've learned fresh with a daily review tailored to your progress. Recognize new verb forms before practicing them from memory. Forms return when they're due for practice, and your mastery map fills in as you learn.
