Features

LinguaMorpha was built around a simple conviction: the grammar of these languages is knowable. There are rules, the irregular forms group into patterns, and once you can see those patterns, the language stops feeling arbitrary.

LinguaMorpha is a morphology-first study app. Latin covers every declension, every adjective pattern, the degrees of comparison where classical Latin has them, macron-accurate checking, plus a sentence parser that labels every word of a Latin sentence. Spanish covers verb conjugation in sixteen tenses, noun gender and plurals, set phrases and thousands of example sentences, and single-word vocabulary. French covers verb conjugation in sixteen tenses, noun gender and plurals, and phrases. All three languages share one marking scheme.

Each course is a complete study system in its own right — pick the one you actually want to learn and ignore the rest. They share machinery (the adaptive engine, the drill screens, the help system), not a learning path. The differences are the size of the catalogue and the grammar specific to each language.

What's in each course

What each course covers, in full, is on its own page: Latin (over 600 verbs, over 650 nouns, the sentence parser and the agreement drill), Spanish (over 1,100 verbs, over 1,600 nouns, over 270 set phrases, the Traps decks) and French (over 900 verbs, over 1,400 nouns, sixteen tenses including the literary ones).

The rest of this page is what they all share.

How the patterns are made visible

In all three languages, conjugation tables mark each form so you can see where it departs from its pattern, and by how much. A form that follows its pattern gets no colour, so the marking tells you something real.

The marks mean the same thing everywhere. Red falls on just the part that departs; a form that is red throughout has to be learned as a whole. An underline marks the ending the pattern predicts, on regular and irregular forms alike — the part you do not have to learn separately. Blue is used only in Spanish, for the separate ending set of the strong preterites (tuve, pude).

The full key, with worked examples, is in the Spanish conjugation tables guide.

How you study

There are five ways in, and all of them share one vocabulary catalogue and one adaptive engine, so an answer given in any of them counts in all of them. Grammar lessons take you through verb, noun and adjective morphology in a fixed order. Theory gathers every theory page of the course in one place: the rules, explained, in grammar text and paradigms you read rather than answer. Practice Sets are ready-made sessions you launch as a unit; run the bundled ones, or build and share your own. Self Study puts you in full control: you choose the words, the groups and tenses, and which drill to run. Tests put every test for your level on one page, with the theory one tap away. And at any time outside a drill, Look up takes any form you type and tells you what it is; in Latin, a second mode parses a whole sentence.

Where you study

iPhone, iPad and Mac are all full study platforms — every drill, Self Study, Practice Sets, Grammar lessons, the reference tables and your progress reports are on each. LinguaMorpha runs natively on all three, with a companion app for Apple Watch. With Universal Purchase, the iPhone/iPad and Mac apps share one purchase, so a language you unlock on one is unlocked on the other. See The app for the platforms and languages.

On the Mac, the app is built for the desktop rather than scaled up from the phone: a sidebar, Settings in its own window, import and export in the File menu, the User Guide in the Help menu, keyboard shortcuts, and a verb's reference sheet you can save as a PDF — made for studying at a desk, with a keyboard.

Apple Watch is deliberately small — a reference, not a place to study: choose verbs and tenses, then read their conjugation. No drills, no progress, no lessons. Spanish and French only.

Adaptive learning

Every answer you give is recorded in a database on your device. Each session's words are chosen in this order:

  1. Words you got wrong last time come first. Answering one correctly removes the flag.
  2. New words and review words fill the remaining places. New words come in order of importance — a combination of CEFR level and frequency, so common A1 words come before rare C2 words. Review words come weakest first, adjusted for how recently you saw them, so the review rotates.

A Learning pace setting (Relaxed / Balanced / Intensive) sets the mix of review and new words. In a flashcard session, a card you get wrong can come round again, but never twice in a row. (Every course is adaptive in the same way — Latin, Spanish and French alike.)

Privacy

Everything stays on your device — no account, no cloud sync, no tracking or analytics. See the full Privacy Policy.

Because nothing syncs through a server, moving your data is always something you do yourself: export your study history and your Practice Sets as files, and import them on another device. Nothing leaves your device unless you export it.
