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, comparative and superlative, 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

Each course is complete on its own — pick the one you actually want to learn and ignore the rest. What each covers, in full, is on its own page: Latin (over 600 verbs, over 550 nouns, the sentence parser and the agreement drill), Spanish (over 1,100 verbs, over 1,400 nouns, over 240 set phrases, the Traps decks) and French (over 900 verbs, over 1,350 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

Three ways to study share one vocabulary catalogue and one adaptive engine, so an answer given in any of them counts in all of them. Two of them — Self Study and Practice Sets — let you choose exactly which words and forms you want to work on.

Choosing what to study

In Self Study, the words in play are decided by one screen, Select word scope, which combines two filters:

Topics — a tree of topic tags (Food, Travel, Health, Family and more). Tags with subgroups expand, so you can select a whole theme or only the subgroups you want.
CEFR level — A1 through C2 — limits the pool to the levels you are working on.

The two filters combine: a word has to pass both. Pick Food, then A1–A2, and you get the beginner-level food vocabulary and nothing else. The scope applies to every Self Study hub at once, in both the reference lists and the drills.

A Practice Set works differently: it brings its own word list and is not affected by your word scope. When you build one, you can also narrow by frequency — how common the words are — which Self Study does not offer. A set you build is saved as a description (word types, levels, frequency, topics, the exercises and the tenses), so it keeps up with the catalogue: new words that match the description join the set.

Self Study

Self Study puts you in full control. You choose the words with the filters above, the verb groups, tenses or other groups in each hub, and which drill to run — meaning, conjugation, recognition, gender and more. Best when you have a specific goal: a particular tense, a topic, or a single grammar point to drill.

Every hub is built from the same four sections, whatever the language and whatever the word type — verbs, nouns, adjectives, adverbs, pronouns, prepositions, numerals, other vocabulary or phrases. Learn the layout once and you know your way around all of them:

Setup — decide what is in the pool: which verb groups and tenses, which noun groups, which word groups. Everything below draws on what you choose here.
Theory — the rules, explained. Grammar text and paradigms you read rather than answer.
Study — browse what you selected, with translations, and open any item for its full forms. Nothing is recorded, so you can look things up without it counting against you.
Drills — active practice: flashcards and graded drills. Every answer is recorded and feeds the adaptive engine that decides what you see next.

The split between Study and Drills is the one worth knowing: looking a form up is never scored, and practising it always is. A hub leaves out a section only where there is nothing to put there — the Spanish Traps decks are closed, so that hub has no Setup.

Practice Sets

Practice Sets are ready-made sessions — a CEFR level, a topic, a single tense — that you launch as a unit instead of setting everything up each time. The app supplies a library for each course that has sets, but the real point is that you build your own: describe the words, tenses and exercises you want, name the set, and run it any time. Export your whole library to one file — a backup, and the way to move your sets between your own devices — or share individual sets with another learner, who imports them after a review screen.

Grammar lessons

Grammar lessons take you through verb, noun and adjective morphology in a fixed order — for Latin through the declensions and the verb system, for Spanish and French largely by tense — each lesson with a Study and a Practice phase. When a lesson introduces new verbs, an Only new box keeps the verb exercises to those verbs; untick it to practise the verbs from earlier lessons too, so older material stays fresh.

The Spanish lessons number over sixty and reach the subjunctive and the imperative: Presente de Subjuntivo at B1 (formation from the yo form, the irregulars it inherits, the six verbs that don't derive, and the triggers), Imperfecto de Subjuntivo at B2 (si clauses and softened requests), and Imperativo (the tú command, the eight short forms, and the negative — which uses the subjunctive again). Five of the sixteen tenses are not part of the lessons, all of them compound tenses, and all can be drilled in Self Study.

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.

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.

Your answers stay on the device that recorded them — there is no cloud sync. To move your study history and Practice Sets to another device, export them as files and import them there. See The app for the platforms and languages.

Adaptive learning

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

Words you got wrong last time come first. Answering one correctly removes the flag.
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, as files you control. You can export your study history and your Practice Sets to files and import them on another device, and you can share individual Practice Sets by exporting just those and sending the file however you like — whoever imports it chooses to rename, overwrite or skip any set with the same name as one they already have. Nothing leaves your device unless you export it.
