The 6 Russian noun cases, explained.

The 6 cases at a glance

Each case answers a different question and is triggered by specific verbs, prepositions, or sentence roles. Here's a one-sentence summary of each, then we'll go deeper.

All six Russian cases in one table

This is the Russian cases chart people screenshot. Six cases down, three genders across, singular and plural in every row. The question words are the fastest way to find the case: ask the question, and the answer tells you the ending.

Noun endings by case and gender

∅ means no ending. Words in -ия, -ие and -ий take -и in the prepositional (в России, в здании). Each case name links to its own page.

One word, six forms

Here's how a single masculine noun (брат - brother) and a feminine noun (книга - book) change across all 6 cases. This is what declension looks like in practice.

All six cases in one sentence

It's possible to use every case in a single Russian sentence. Here's one:

Case triggers: what forces each Russian noun case

Choosing a case is rarely a judgment call. Something in the sentence forces it: a preposition, a verb, a number, a negation. Learn the triggers and the endings stop feeling arbitrary.

The instrumental has the friendliest mnemonic in the system: it answers "with what?" for tools and "with whom?" for company, and Russian uses the same ending for both. с бра́том (s bratom) - with my brother, ру́чкой (ruchkoy) - with a pen.

The Russian grammar rules that govern the cases

Six rules do most of the work. They apply across the whole case system, so each one you learn pays off in all 6 columns of the table.

1. Numbers change the case of what they count

Russian counts in three bands. One takes the nominative. Two, three and four take the genitive singular. Five and up take the genitive plural. одна́ кни́га (odna kniga) - one book, две кни́ги (dve knigi) - two books, пять книг (pyat knig) - five books. The rule loops: 21 goes back to the nominative, 22 back to the genitive singular.

2. Negation pulls the object into the genitive

Say a thing exists and it's nominative. Say it doesn't and it turns genitive. Здесь есть вода́ (Zdes yest voda) - There is water here becomes Здесь нет воды́ (Zdes net vody) - There is no water here. This is also how Russian says "have": у меня́ есть (u menya yest) puts the owner in the genitive after у.

3. в and на take two different cases

The same preposition means two things depending on the case you pair it with. Accusative for motion toward, prepositional for sitting still. Я иду́ в шко́лу (Ya idu v shkolu) - I am going to school against Я в шко́ле (Ya v shkole) - I am at school. One vowel carries the entire difference between going and being.

4. Animacy decides the accusative

For masculine singular nouns and for every plural, the accusative copies the genitive when the noun is a person or animal, and copies the nominative when it isn't. Я ви́жу стол (Ya vizhu stol) - I see a table against Я ви́жу бра́та (Ya vizhu brata) - I see my brother. Feminine singular nouns ignore this and take -у either way.

5. The spelling rule overrides the ending

After ж, ч, ш, щ, к, г, х, Russian writes и where the table says ы. So кни́га gives кни́ги in the genitive rather than the кни́гы the chart would predict. The rule is mechanical, it never has exceptions, and it explains a large share of the endings that look wrong at first.

6. Everything in the phrase agrees

Case is a property of the whole noun phrase. Put a noun in the dative and its adjective, its possessive and any pronoun pointing at it all move too. моему́ ста́ршему бра́ту (moyemu starshemu bratu) - to my older brother carries the dative three times in a row. This is why drilling nouns alone stalls out, and why the declension tool has a phrase mode that declines the adjective and the noun together.

Learning order: which cases to tackle first

Don't try to learn all six at once. Here's a practical order based on frequency and usefulness:

• Weeks 1 and 2: Nominative + Accusative. Subjects and direct objects - you need these for every sentence.
• Weeks 3 and 4: Prepositional. The simplest oblique case. Covers "at/in" locations and "about" topics.
• Weeks 5 to 8: Genitive. The biggest case by usage. Possession, absence, numbers, negation, partitive. Take your time.
• Weeks 9 and 10: Dative. Indirect objects, age, feelings, impersonal constructions.
• Weeks 11 and 12: Instrumental. Means, with, professions after быть, seasons.

This sequence is built into Slova's curriculum - you encounter each case in the order that makes sentences possible, not the order textbooks list them.

How to practice the cases until they stick

Reading the table tells you what the endings are. Producing them in a sentence is a separate skill, and it's the one you need when you speak. Four habits build it.

1. One case at a time. Learn its job, its trigger words and its endings, then practice only that case for a few days. The learning order above gives the sequence.
2. Type the ending instead of picking it. Recall is harder than recognition. Slova learners got 80% of case endings right when they picked from options, and 56% when they typed them (the same 35 learners, July to October 2026).
3. Practice inside a sentence. The word before the noun tells you the case: в Москве (v Moskve) - in Moscow, без воды (bez vody) - without water, с другом (s drugom) - with a friend. Learn each ending with its trigger.
4. Come back to the forms you miss. A missed ending needs a second try the same day and another a few days later. Spaced repetition schedules that for you.

Train the dative

1. 1 · Learn
   A lesson for every case
   What the case does, when to use it, the endings by gender, and example sentences. Tenses, aspect and verbs of motion have lessons too.
2. 2 · Drill
   You type the ending in a sentence
   After each answer, Slova names the word that called for the case, so the rule ties back to the sentence.
3. 3 · Adjectives
   Adjectives and the plural, too
   Every adjective has its own forms. With living nouns the accusative takes the genitive form, and Slova tells you when that rule applies.
4. 4 · Fix
   Miss it, see why
   Both forms of the word, the rule in one line, and the full lesson one tap away. Missed forms come back before the session ends.
5. 5 · Track
   See which case is weak
   Each of the 6 cases, and the plural, gets its own score. The weakest one leads your next session.
