Nothing scares English speakers off a language faster than the word "cases". Say "Russian has six cases" or "Finnish has fifteen" and people picture a wall of tables to memorise before they can order a coffee.
That picture is wrong in a way that matters. A case system is not a list of exceptions; it is the language showing, on the word itself, what English shows with word order. And you already use one.
You already know three cases
Look at English pronouns:
- He saw the dog. (he is doing the seeing)
- The dog saw him. (he is being seen)
- That is his dog. (the dog belongs to him)
He, him, his: one person, three forms, chosen by the role he plays. That is a case system. English lost it almost everywhere else - "the dog" is "the dog" whether it bites or is bitten - so we rely on word order instead. The dog bit the man and the man bit the dog differ only in the order.
A case language keeps that machinery running on nouns, adjectives and articles too. The payoff is that word order is freed up to show emphasis or information flow, because the endings already say who did what.
What the common cases do
Names differ between grammars, but the jobs are recognisable:
- Nominative - the subject, the one doing it. The "dictionary form".
- Accusative - the direct object, the thing acted on. I see the dog.
- Dative - the recipient or the one affected. I give the dog a bone.
- Genitive - possession and "of". the dog's bone.
Many languages add more: an instrumental (with, by means of), a locative (in, at), a vocative (for addressing someone). Finnish goes further and splits location into a whole set - in, into, out of, on, onto, off.
The languages we teach, by case load
No noun cases at all: Spanish, French, Italian, Portuguese and Catalan lost them on the way from Latin, and show roles with word order and prepositions - as English does. Dutch, Swedish, Norwegian and Danish have also shed almost all of theirs. Pronouns keep traces nearly everywhere.
German - four cases, mostly on the article. Nominative, accusative, dative, genitive. The good news is that the noun itself usually changes little; the work is in der/den/dem/des and the adjective endings. Start with the accusative, which for most nouns is just der becoming den, then the prepositions that always take the dative. In everyday speech the genitive is often replaced by von plus the dative.
Modern Greek - four. Nominative, genitive, accusative and vocative; the ancient dative has gone. Like German, the article carries much of the signal. See the genitive.
Romanian - fewer than it looks. Romanian keeps a case distinction that its Romance siblings lost, but many forms are shared, so grammars often describe it as two main pairs (nominative-accusative and genitive-dative) plus a vocative.
Russian - six, and Polish - seven. Nominative, accusative, genitive, dative, instrumental and prepositional (locative); Polish adds the vocative. This is where cases stop being an article problem and become an ending problem - on nouns, adjectives and pronouns, varying by gender and by the noun's ending. It is real work. It is also highly regular once the patterns settle, and a few uses cover a lot of ground: Polish puts the object of a negated verb in the genitive (genitive after negation), and Russian expresses many feelings with the dative (мне грустно - literally "to me it is sad"). Our Polish vs Russian page sets the two side by side.
Turkish - about six, all as suffixes. Turkish case endings attach to the end of the word and change their vowel to match it (vowel harmony), so one case has several spellings. One detail English speakers like: the accusative ending is only used for a definite object - the accusative -i marks "the book", not "a book".
Finnish - usually counted as about fifteen. It sounds like the worst case and in practice is less alarming than the number, because many of them are spatial pairs that do the job English prepositions do. Talossa is "in the house", talosta "out of the house" - see the local cases -ssa, -sta and -Vn. You are learning suffixes instead of prepositions, not fifteen abstract ideas.
Irish - traces. Irish keeps a genitive and a vocative that visibly change nouns, and its initial mutations do much of the signalling work other languages give to endings.
Korean - particles that play the same role. Korean nouns do not change, but small particles after them mark subject, object, topic and more - which is why some grammars call them case particles. Start with the three particle pairs.
How to learn a case language without drowning
- Don't start with the table. A full declension chart is a reference, not
a lesson. Look at it once so you know it exists, then close it.
- Learn one case in one situation. The object case when you order food.
The locative when you say where you live. Each new case arrives attached to something you actually want to say.
- Learn words with their article or ending attached. Den Hund, not
Hund. Chunks keep the case inside the phrase, where you will retrieve it.
- Accept being wrong for a while. A wrong ending rarely stops a native
speaker understanding you. Keep talking, and let corrections do the work.
That is how our curriculum is built. Each language's grammar pages are organised around what you need at each level, with a plain-English note before the drills that practise it, and a case appears in the unit where it is first needed rather than all at once. When the tutor catches a wrong ending in conversation, the correction is saved to your "Your mistakes" drill so it comes back until it sticks.
Cases are a real cost, and the languages that have many of them take longer to learn. But the cost is paid one case at a time, and the first one is the he-and-him distinction you already had.
