Features¶

LinguaMorpha is a morphology-first language platform. Latin covers every declension, every adjective pattern, comparative and superlative, macron-accurate checking, plus a sentence parser that handles arbitrary Latin text. Spanish covers full verb conjugation across every major tense, noun gender and plurals, ~6,000 phrases, and single-word vocabulary. French covers full verb conjugation, noun gender and plurals, with irregulars colour-coded as in Spanish. Italian and Portuguese arrive as free updates over the coming months.

Each module is a complete study system in its own right — pick the one you actually want to learn and ignore the rest. They share infrastructure (the adaptive engine, the drill loop, the example-sentence rendering, the help system), not a learning path. The differences are catalogue size and language-specific grammar quirks.

Latin¶

Latin gets the deepest morphological coverage because Latin's morphology is itself the deepest. Coverage as of v1.0:

~300 verbs across all five conjugations, with full tense paradigms (present-system + perfect-system, indicative + subjunctive + imperative, active + passive, plus participles, gerundive, infinitives, supine).
~270 nouns across all five declensions, including i-stem 3rd-declension, 4th-declension neuters, and plūrāle-tantum entries (moenia, līberī).
~150 adjectives across all five patterns (1st/2nd-decl -us/-a/-um, -er/-a/-um, 3rd-decl two-ending fortis/-e, 3rd-decl one-ending ingēns, 3rd-decl three-ending ācer/-cris/-cre) — with comparative and superlative derivation.
11 pronouns with full case×number×gender paradigms (the personal, demonstrative, relative, and interrogative classes).
29 numerals — ūnus / duo / trēs with full declension, quattuor through centum as indeclinable reference cards.

Macron-accurate answer checking¶

The default answer-check is lenient on macrons — typing rosa when rōsa is correct counts as right with a gentle reminder. A toggle in Preferences switches this to strict for users who want the long vowels in their muscle memory. (Macron drill — a dedicated drill that asks you to type a stripped word with its macrons restored — arrives in v1.5.)

Sentence parser¶

Open Self Study → Identify a Form and switch to Sentence mode. Paste any Latin sentence — Caesar's opening, a Vulgate verse, your homework — and tap Parse. Each word becomes a chip showing its lemma, case, number, gender, tense, voice, and translation. Words with multiple parses (Latin is full of these — vēris could be gen.sg of vēr or 2sg.fut.ind of vēreor) show every parse stacked, sorted by pedagogical likelihood. Tap a chip to jump to that word's full paradigm.

Concordance drill¶

The drill that no other Latin app implements. Show a one-line Latin sentence with a blank where an adjective should go. The noun appears in its inflected form; the learner picks the adjective form that agrees in case, number, and gender. Wrong answers explain which axis was wrong — "bonum agrees with a neuter noun — puella is feminine."

Example sentences¶

Every noun and adjective in the catalogue has three auto-generated example sentences that pipe the lemma through the same template library the concordance drill uses. About 1,100 sentences in total across the Latin catalogue, all rendered in real Latin syntactic context with the focus form bolded and a case+number tag below. Hand-curated examples take precedence where they exist (about 28 nouns so far); the auto-examples fill the gap for everyone else.

Spanish¶

A complete Spanish module, fully wired into the same Setup / Study / Test pipeline as Latin. Nothing here assumes you know any Latin — Spanish stands entirely on its own.

Verbs¶

Practise conjugation across all the major Spanish tenses for around 1,100 verbs.

Conjugation Drill — given a verb, tense, and person, type the correct form or pick from multiple choices. Switchable on the fly.
Recognition — given a conjugated form, identify the verb, tense, and person using three scroll wheels.
Word Meanings flashcards — Spanish ↔ your language, both directions.
Past Participle, Gerundio, and Indefinido drills — focused flashcard decks for the forms that carry the most irregularity. The decks always include all irregular members of your selection, plus a sample of regulars.
Conjugation tables — full tables for every verb, with irregular forms colour-coded: red on just the parts of a form that deviate from the regular pattern (stem changes, irregular yo forms, y-verbs, irregular future stems), and the whole form in red where it's entirely irregular — including strong preterite verbs and forms of ser, ir, haber.

Verbs are filterable by CEFR level (A1–C2), frequency, topic (travel, food, work, …), and verb group (regular -ar / -er / -ir, stem-changing e→ie / e→i / o→ue, go-verbs, zco-verbs, j-verbs, guir-verbs, y-verbs, uir-verbs, strong preterite, reflexive, impersonal, gusto-type, stative). You can also toggle individual tenses on or off.

Nouns¶

Around 1,300 Spanish nouns, with practice for gender, plurals, and alternate-gender pairs.

Pick the correct article — el or la?
Singular / Plural — produce the correct plural from the singular form.
Alternate gender pairs — practise nouns whose meaning changes with the article (el capital = money/capital, la capital = capital city; el orden = order/sequence, la orden = command).
Meaning flashcards — Spanish ↔ your language.
Reference notes — gender rules and an explainer for alternate-gender pairs.

Filter by CEFR level, frequency, or topic (home, food, body, technology, …).

Personal topics¶

In addition to the bundled topics that ship with the app, you can add your own topics to any verb or noun. Open a word's detail view, tap + in the Topics row, and either type a new tag (like exam, tricky, or kitchen) or pick from one you've used before. Personal topics live alongside the bundled topics in the same filter and behave the same way — you can mix them freely with CEFR level, frequency, and the standard topic categories.

The data is stored locally on your device. There is no cloud sync; tags survive app updates but stay on the device they were created on.

Phrases and Words¶

Phrases is the largest drillable pool in the app — around 6,000 entries. It combines ~240 curated set phrases (greetings like buenos días and mucho gusto, time expressions like en punto and de vez en cuando, conversational chunks like a pesar de and sin embargo) with ~5,700 example sentences synthesised from the verb and noun catalogues. Every example sentence you'd see on a verb or noun detail card is also drillable here as its own phrase. Toggle the Example topic to switch the synthesised layer on or off as a single bucket.

Words covers single-word vocabulary that isn't a verb or noun — adjectives (with masculine/feminine pairs merged into one entry), adverbs, prepositions, conjunctions, and numbers. Filterable by grammatical category.

Both sections follow the same Setup / Study / Test pipeline as Verbs and Nouns. Practice is via flashcards in either direction (Spanish ↔ your native language, or a random mix).

Speech¶

LinguaMorpha uses iOS speech synthesis to read Spanish forms aloud. iOS includes Spanish voices at three quality levels — Standard, Enhanced, and Premium. The Enhanced and Premium voices are free to download from iOS Settings and sound much better than the default. See the Getting Started guide for step-by-step instructions. A speed slider in the app lets you slow speech down for listening practice.

Latin doesn't have a native iOS TTS voice in v1.0. (An approximate classical pronunciation mode using the Italian voice with a transformation layer arrives in v1.5.)

External dictionary lookups¶

Every Spanish verb and noun detail view has a Look up row with chip buttons for four well-known online dictionaries: Linguee, WordReference, Reverso, and RAE (the Real Academia Española). Tap a chip and the lookup opens in an in-app Safari sheet — you don't leave LinguaMorpha. The toggles for which services appear live in Settings → Dictionary Services. (Latin doesn't surface these — the sentence parser is the equivalent reference path.)

Adaptive learning¶

Every answer you give is recorded in a local database on your device. Sessions are built using a strict priority order:

Unseen words first, ordered by significance — A1 very-common words before C2 rare words.
Previously-seen words, ordered by correct rate, weakest first. Ties broken by oldest last-seen date.

A Learning Pace setting (Relaxed / Balanced / Intensive) adjusts the balance between new vocabulary and review. Within a single session, each word appears exactly once. (Adaptive learning is fully wired for Spanish in v1.0; Latin-side performance tracking lands in a follow-up release — drills work, they're just not yet adaptive.)

Guided Grammar Lessons (v1.3)¶

The structured-curriculum side of the app returns in v1.3. Lessons walk through verb and noun morphology in textbook-aligned chapters — paced to Wheelock or LLPSI for Latin, paced by tense for Spanish, with Study and Practice phases for each. An Include previous toggle lets you mix in earlier lessons to keep older material fresh.

Hidden in v1.0 to keep the launch focused; the implementation is there and tested, just feature-flagged off.

What's coming¶

LinguaMorpha is a platform. Latin, Spanish, and French are available now; Italian and Portuguese complete the Western Romance family as free updates, plus the structured-lessons system. Each new module is a complete study system in its own right — no required order, no prerequisite climb. Every one of these is included free with the app.

v1.3 — Guided lessons return (Latin + Spanish first).
v1.4 — Italian.
v1.5 — Macron drill, etymology bridge, approximate classical TTS for Latin.
v1.6 — Portuguese.

Roadmap order may shift; every module listed here is committed.

Settings¶

A few settings let you tune how the app fits your study habit:

Active language — flip between Latin and any installed modules (Spanish in v1.0).
Display language — single toggle (🇬🇧 / 🇳🇱) flips the app's chrome and the translations on flashcards between English and Dutch.
Session Size — how many words appear in each session: 10, 20, 30, 50, or All.
Learning Pace — Relaxed, Balanced, or Intensive. Biases the balance between new vocabulary and review.
Auto-advance — when on, a correct answer moves to the next card after a short pause.
Speech — pick a Spanish voice and adjust the speaking speed.
Strict macrons — switches the Latin answer-check from lenient (macron-folded) to strict.
Dictionary Services — choose which of Linguee, WordReference, Reverso, and RAE appear in the Look up row on Spanish verb and noun detail views.

You can reset your study history from Settings → Data → Reset Progress — by module, by category, or all at once. Your word-selection filters are not affected.

Privacy¶
