Latin is morphology. Make it automatic.
Every ending, every macron, drilled until a sentence stops being a puzzle and becomes a text.
You can know every paradigm by heart and still come unstuck in a test. Reciting a paradigm is a different act from recognising rēbus in the middle of a sentence.
Vocabulary apps test a list someone typed in. Parsers give answers, but never ask anything. LinguaMorpha does both, and in two directions: "what is corporibus?" and "give the dative plural of corpus".
It can do that because it builds every form itself. It tests any form, marks your answer down to the macron — lenient or strict, you choose — and on a mistake shows the paradigm behind it. Where a form has several readings, all of them count: rosae is genitive and dative singular, nominative and vocative plural.
Stuck mid-translation? The parser is already there — plus ten passages, from a beginner's story to unaltered Cicero, translated line by line.
Every form has been compared against an outside source. Every difference is documented in the open, on the site.

Who it is for
The self-learner. You are doing Latin without a teacher — Lingua Latina per se Illustrata under your own steam, or a textbook you work through yourself. Nobody tests you and nobody tells you it is nearly right. The app asks for the form instead of showing it, marks your answer down to the macron, and on a mistake names the paradigm behind it.
The reader. You can follow a text with a dictionary and a grammar but not without them. The parser checks your reading line by line, the readings put a parse behind every word, and the drills close the gaps the parser keeps finding.
The school pupil. Paradigms are not learned by reading them but by producing them, again and again, until they come by themselves. Scope the drills to the declensions, patterns and tenses your chapter has introduced — Wheelock, the school course, whichever it is — and drill until they stick: type the form for a case and number, conjugate in the tense asked, recognise what a form is. Every answer is checked, macron and all, not just shown. The app remembers what you got wrong and comes back to it. Besides that: the tables on your phone for the test, and the sentence parser for the homework.
How it compares. For Latin the alternatives are textbook companion sites, vocabulary lists and flashcard decks. LinguaMorpha puts the catalogue, the paradigm tables, the production and recognition drills, the parser, the readings and sessions that track what you get wrong into one app, instead of a collection of separate tools. It does not teach you to speak Latin, and it does not replace your textbook; it is what you use beside it.
Five ways to study
Grammar lessons, Theory, Practice Sets, Self Study and Tests — the same five in every course, sharing one catalogue and one adaptive engine, so an answer given in any of them counts in all of them. What each one is for →
From paradigm to text
Every form, every macron. Every noun, adjective, pronoun and verb form in the course is stored with its macrons, and the typed drills check them. The check is lenient by default: rosis for rosīs still counts, and the feedback reads Correct — watch the macron and shows where the long vowel goes. Turn on Exact spelling (Settings → Study) and a missing macron is wrong — for when vowel length is what you are learning. Either way, the written form with its macrons is always the authority.
The five declensions, in one view and drilled both ways. The synopsis puts the endings of all five declensions side by side, singular and plural, and switches to a detailed grid with the neuter columns of the 2nd, 3rd and 4th. From there, Decline the noun asks you to produce the form a case and number call for, and Recognise the form asks what a form is — and in Latin the honest answer is often more than one, so every correct analysis of an ambiguous form counts. Select noun groups narrows the drills to the declensions you are working on, i-stems and the fourth-declension neuters included.
All five declensions, side by side
The endings of all five declensions in one grid, singular and plural. Switch to Detailed to add separate neuter columns for the 2nd, 3rd and 4th declensions.
Decline the noun
Produce the form that the case and number ask for — type it, or pick it from a list — with macron checking as lenient or as strict as you choose.
The agreement drill
The noun is already inflected and the adjective is missing. Pick the form that agrees; the explanation names the noun's gender, case and number.
Noun and adjective together. Paradigms are learned one word at a time, but Latin is read two words at a time. In the agreement drill a short sentence appears with a blank where an adjective belongs; the noun is already inflected, and you pick the adjective form that agrees with it in case, number and gender. After each answer a card explains the choice — pulchram agrees with rosam (f. Acc. sg.). All five adjective patterns take part.
The verb system in full. Indicative, subjunctive and imperative, active and passive, plus the six infinitives, all four participles, the gerund and the supine — every tense can be switched on or off in Select tenses, so the drills follow your textbook rather than running ahead of it. Tap any verb for a tabbed screen titled with the verb and its principal parts (amō, amāre, amāvī, amātum): Conjugation filtered by mood, tense, stem and voice; Regularity, which goes through the verb tense by tense, names the stem each tense is built on and shows in amber the stems you have to memorise; and a printable one-page Reference sheet. Then produce a form, recognise one, name the verb from its principal parts, or take the two choice drills — Perfectum or imperfectum and Indicativus or coniunctivus — that ask which tense or mood a sentence needs.
Type any form and see what it is. Look up takes whatever you met on the page — ferrent, rēbus, ductūrōs — and tells you what it is: the word it belongs to, its meaning, and its case and number or tense, person and voice, with every reading of an ambiguous form listed. It searches every form of every verb, noun and adjective in the course, not just the headwords. Macrons and capitals are optional, a word in your own language finds the Latin, and a form you half-remember or misspell still lands on the nearest headwords. A verb opens at the tense you typed; a noun opens with that form highlighted in its table.
From forms to sentences. Once the forms are there, the course turns them towards text. Nouns carry over 1,700 example sentences, each translated and labelled with the case and number the noun takes; adjectives show short sentences with the adjective agreeing with a noun; many verbs add tense examples and their separate senses. The sentence parser takes a whole sentence — a line of Caesar, a Vulgate verse, your homework — and returns every word as a chip with the lemma of its most likely reading and a badge when there are more; tap a chip for every possible parse, and nouns, adjectives and verbs open their full entry with the matching form highlighted. It ignores macrons and capitals, strips punctuation and splits enclitics such as -que and -cum, draws on more than 2,000 lemmas at the level of an introductory course, and marks what it does not know as unknown. A literal word-by-word gloss can be copied, and on devices with Apple Intelligence a Translate button asks for a machine translation. And the ten annotated readings — from a beginner's story through the Vulgate, Catullus and Phaedrus to unaltered Caesar and Cicero — put the parser under every word, an English and a Dutch translation under every line, and a teacher's note on the constructions worth noticing.
Sentence parser
Paste a Latin sentence; every word the catalogue knows comes back parsed, with a literal gloss you can copy.
Annotated readings
Ten passages, sorted by difficulty, with a translation under every line and a parse behind almost every word.
Beside your textbook. The course carries no chapter tags, so there is no per-chapter filter for Wheelock or Lingua Latina; instead you scope the drills by declension, adjective pattern, verb group and tense to match what the chapter has introduced, read the chapter, and drill the same material here until it is automatic. Every answer is recorded on your device, the words for each session are picked from your selection on the basis of your answer history, and an Incorrect answers switch limits a session to what you got wrong before. If you would rather be led, the Grammar lessons go through the same ground in order: twelve lessons in four modules, from the first declensions and the verb's present and perfect systems to the passive, pronouns, participles and the subjunctive. And when you meet Latin outside the app, the parser is the quickest way to check your reading.
What else does it look like? →
For the teacher
What a pupil does with it. The app does not replace the course book; it is what the pupil opens beside it. Declensions, adjective patterns, verb groups and tenses each switch on and off separately, so the drills can be limited to what the chapter has introduced — this week's paradigms, not next month's. Every session picks its words from the answer history, and the Incorrect answers switch keeps a session to what went wrong before. The reports show which tenses and words a pupil has practised, how well, and what has stuck.
A set for the class. A practice set is a session you put together yourself — these words, those tenses, this kind of exercise — and share as a file, by AirDrop, mail or the school's learning platform. The pupils import it and drill the same material. For next week's test, or for the paradigm half the class still has not got.
Checking homework. Paste a sentence into the sentence parser and every word comes back analysed, with every reading of an ambiguous form. It is the fastest check on a reading that does not work: rēbus is not an accusative, whatever the pupil thought. The readings — from a beginner's story through the Vulgate, Catullus and Phaedrus to unadapted Caesar and Cicero — carry a parse behind every word, an English and a Dutch translation under every line and, at the constructions worth a pause, a teacher note: the jussive subjunctive in the Pater Noster, the ablative of respect in Caesar, the accusative and infinitive in Cicero.
The words of the classroom. The app names tenses and moods in Latin (Praesens, Perfectum, Coniunctivus) in every interface language; names a verb by its first person (amō) in the English interface and by its infinitive (amāre) in the Dutch one, with the principal parts after it; orders the cases nominative – genitive – dative – accusative – ablative – vocative, as the Dutch and German school grammars do; and labels the rows of a conjugation 1 sg … 3 pl, without a pronoun. Macrons follow the Oxford Latin Dictionary and Ørberg's Familia Romana. Every one of these choices is stated in one place in the guide, so a pupil who sees something other than in the book knows why.
What it is not. No teacher dashboard, no accounts, no class administration, no results sent to the school. That is a choice: a pupil's answers stay on the pupil's own device, and there is no server for them to go to. To see how a pupil is doing, ask to see the report — or have it exported as a PDF.
How we know the forms are right
The app's author is not a classicist. So the correctness of the forms does not rest on his judgement but on comparison with sources a classicist does trust, and on writing down every difference.
Every verb form against Wiktionary. All 66,290 forms the app produces for all its verbs — every person, tense and mood, active and passive, infinitives, participles, gerund and supine — have been compared with Wiktionary's conjugation tables. 66,048 agree letter for letter; 93 differ only in a vowel length, where Wiktionary leaves the length open and the app commits to one; 65 differ outright; and 84 are forms the app produces that Wiktionary does not list — the full passives of verbs for which Wiktionary gives only the third person. Every difference is written down, with what it is and why the app keeps its form or does not — and the register is there to read, on the Open questions page.
Every declined form against Collatinus. All 42,096 forms of the nouns, the adjectives in three degrees and the pronouns have been compared with Collatinus, the lemmatiser by Yves Ouvrard and Philippe Verkerk that Biblissima distributes. 41,629 agree, the positional lengths before ns and nf included; 43 differ only in a vowel length; 394 differ outright, and every one has been judged and recorded: a choice between grammars, a form Collatinus lacks or writes differently, or an open question. The rest are forms the app leaves out, such as the plural of Iuppiter and the genitive plural of spēs. The slips the comparison found on our side were fixed before anything was counted.
Every disagreement is on paper. The differences that remain live in a register with their reasons — turrim or turrem for the accusative of turris, the vocative of aureus, the stem of simplex. Some are decided; a handful are open, and those go to a classicist rather than being settled by us — they are listed on a page of their own. The register also guards the future: a change to the app that moves one more form away from the source fails the check until someone has judged the difference.
What this does not prove. That a form is right says nothing about the translations, the example sentences and the teacher notes; those were written by the author and have not been read by anyone with a degree in classics. A teacher who finds a mistake in them helps the app most by reporting it — support reads every message.
For the school
One price per pupil, no subscription. Latin is a one-time purchase in the App Store, on the pupil's own iPhone, iPad or Mac; with the same Apple ID it is unlocked on all of them at once. No annual licence, no renewal.
21 days free first, for the whole class. Every pupil can use the complete Latin course for 21 days without paying. That is enough for a trial with a class before anyone buys.
No accounts, no data. The app asks for no name, no email address, no age. Answers, progress and settings stay on the device; there is no server, no analytics, no tracking. For the school's data-protection review that is the short answer: no personal data is processed. The long answer is the privacy policy.
One app for the modern and the classical languages. The same app holds Spanish — over 1,100 verbs in sixteen tenses, the subjuntivo included — and French — over 900 verbs, the passé simple included — with the same drills, reports, practice sets and grammar lessons, and the same rule that nothing leaves the device. A pupil taking Latin and French learns both the same way; a school teaching all three has one app to assess. Each language unlocks on its own, or all three together as Unlock all languages.
iPhone, iPad and Mac. The same app on all three, with the same tables and drills: the school iPad in class, the pupil's own phone on the train, the Mac at the desk. One purchase covers every device on the same Apple ID; progress stays on each device, since there is no account to sync it through. Not for Android, Windows or Chromebook.
Three interface languages. The app, the guide and this site come in English, Dutch and Spanish; the pupil chooses, independently of the course. An international school or a bilingual stream runs the app in English, with the same Latin terms and the same tables.
Purchase by the school. A school edition that the school buys itself through Apple School Manager — licences the school owns, reassigned to the new class every year, with Apple's education discount from twenty copies — is possible, but does not exist yet. We will build it as soon as a school wants to buy it; if yours does, say so through the Support page. Until then the answer is: the pupil's own device, one purchase, and 21 days free for the whole class.

The grammar, in detail
Exactly which forms, groups and patterns the course covers — open for the reference
Verb grammar
The full classical tense system: indicative, subjunctive and imperative, active and passive, plus the non-finite forms. Each tense can be switched on or off in Select tenses.
Indicative — present system (active and passive)
- Praesens
- Imperfectum
- Futurum
Indicative — perfect system (active and passive — the passive built with the perfect participle and esse)
- Perfectum
- Plusquamperfectum
- Futurum Exactum
Subjunctive — four tenses (active and passive)
- Coniunctivus Praesens
- Coniunctivus Imperfectum
- Coniunctivus Perfectum
- Coniunctivus Plusquamperfectum
Imperative
- Present (the everyday "do this!")
- Future (formal register — laws, prayers, maxims)
- Their passive forms
Non-finite forms
- Six infinitives (three tenses × two voices)
- All four participles: present active, perfect passive, future active, and the future passive or gerundive
- Gerund (the verbal noun)
- Supine (accusative in -um for purpose, ablative in -ū for respect)
Verb groups. The verbs are filed in six groups: the 1st (-āre), 2nd (-ēre), 3rd (-ere), 3rd-iō and 4th (-īre) conjugations, and the fully irregular verbs (sum, possum, eō, fīō and their compounds). Ferō, volō, nōlō and mālō sit in the 3rd conjugation with their irregular forms stored one by one.
The verb detail. Tap any verb for a tabbed screen — Conjugation · Regularity · Reference sheet — titled with the verb and its principal parts. Conjugation can be filtered by mood, tense, stem and voice. Regularity goes through the verb tense by tense, names the stem each tense is built on and shows in amber the stems you have to memorise. Reference sheet is a printable one-page PDF of the active voice.
Drills. Produce a form or recognise one — every analysis of an ambiguous form counts — name the verb from its perfect or supine in Principal parts, and two choice drills, Perfectum or imperfectum and Indicativus or coniunctivus, that ask which tense or mood a sentence needs.
Noun grammar
All five declensions:
- First (gen. -ae, almost all feminine): puella, aqua, rosa
- Second (gen. -ī, masculine -us or neuter -um, plus the -er nouns): servus, bellum, puer
- Third (gen. -is, all genders) — including the i-stems (urbs, cīvis, mare) and nouns in -or, usually masculine, with feminine exceptions such as arbor
- Fourth (gen. -ūs, mostly masculine, with the feminines manus and domus and the neuters cornū and genū): exercitus, frūctus
- Fifth (gen. -ēī or -eī, almost all feminine, with diēs usually masculine): diēs, rēs
Choosing what to practise. Select noun groups narrows the drills to the declensions you want. The two nouns whose paradigms are stored form by form rather than generated, vīs and Iuppiter, have an Irregular row of their own and are drilled like any other noun. Drill a noun both ways: Decline the noun asks for a form, Recognise the form asks what a form is.
Adjective grammar
All five textbook patterns:
- 1st/2nd-declension (-us / -a / -um): bonus, magnus
- 1st/2nd-declension -er (-er / -a / -um): pulcher, miser, sacer — the same endings, but the masculine nominative singular ends in -er
- 3rd-declension two-ending (fortis / forte): masculine and feminine share a form, the neuter has its own
- 3rd-declension one-ending (ingēns, gen. ingentis): one nominative for all three genders, with the stem shown by the genitive
- 3rd-declension three-ending (ācer / ācris / ācre): three different nominative singulars
Comparative and superlative are formed for the adjectives that have them in classical Latin (-ior / -ius, then -issimus, with -rimus for -er adjectives and -limus for facilis and its family), and not for adjectives in -eus, -ius and -uus (aureus, arduus), the possessives or the ordinals. The irregulars — bonus → melior → optimus, magnus → maior → maximus, malus → peior → pessimus, parvus → minor → minimus — are stored explicitly. The sentence parser recognises all of these forms; the drills work with the positive degree: Decline the adjective asks for a form, Recognise the form asks for its case, number and gender, and the Agreement drill matches it to a noun.
Pronouns, prepositions and numerals
Pronouns — every form stored individually, grouped by class: personal (ego, tū, reflexive suī), demonstrative (is, hic, ille, iste, ipse, īdem), relative (quī), interrogative (quis) and indefinite (aliquis, quīdam, quisque, nēmō, alius …). The form drill asks for a case, number and gender and offers the same pronoun's other forms as the wrong options.
Prepositions — the Case-government drill asks which case each preposition governs.
Numerals — the cardinal numbers. Ūnus, duo and trēs decline and get a full table; the others, from quattuor to centum and mīlle, are indeclinable and show a card with their single form.
