One Noun Through All Six Cases (Worked Examples)

Paradigm tables show you the six case forms of a noun stacked in a column, but they don't show you why you'd ever use them. This page does the opposite: it takes one word you already know, drops it into six ordinary sentences, and lets you watch the ending change as the word's job in the sentence changes. That is the single most important idea in the whole case system — case = role. The same magazine can be the thing lying on the table, the thing you're reading, the thing you don't have, and the thing you're thinking about, and each role gives it a different ending. We'll do the full tour twice: once with a masculine noun, журна́л ("magazine"), and once with a feminine one, шко́ла ("school"), so you can see the gender-specific endings line up side by side.

The masculine tour: журна́л ("magazine")

Here is журна́л in all six cases, each in a real sentence, each tagged with the question it answers.

Now the sentences. Watch only the ending of журна́л as you read down.

Nominative — журна́л (the subject):

Accusative — журна́л (the direct object). For a masculine inanimate noun, the accusative looks identical to the nominative — but its role is completely different:

Genitive — журна́ла (here, absence with нет):

Dative — журна́лу (the noun something is directed toward; here, "thanks to"):

Instrumental — журна́лом (here, the thing you're "interested in," интересова́ться + instrumental):

Prepositional — журна́ле (the topic, after о "about"):

So one word, журна́л, becomes журна́л / журна́л / журна́ла / журна́лу / журна́лом / журна́ле — six roles, five distinct shapes (nominative and accusative coincide here because the noun is inanimate). Nothing about the magazine changed; only its job did.

The feminine tour: шко́ла ("school")

Now the same six roles with a feminine noun, шко́ла. Feminine -а nouns have their own set of endings, and putting them next to журна́л shows you exactly where the genders diverge.

Notice immediately the two big contrasts: the feminine noun has a visible, distinct accusative (шко́лу, not шко́ла), and its instrumental ends in -ой (шко́лой) rather than masculine -ом (журна́лом). The sentences:

Nominative — шко́ла (the subject):

Accusative — шко́лу (the direct object — and here the ending really does change):

Genitive — шко́лы (the "of" relation):

Dative — шко́ле (the recipient/destination; here, "towards"):

Instrumental — шко́лой (here, "next to," ря́дом со):

Prepositional — шко́ле (location/topic, after в or о):

So шко́ла runs through шко́ла / шко́лу / шко́лы / шко́ле / шко́лой / шко́ле — and here, unlike журна́л, the accusative (шко́лу) is plainly different from the nominative (шко́ла). Note too that dative and prepositional coincide for this noun (both шко́ле), exactly as nominative and accusative coincided for журна́л. Different genders hide their "twins" in different places.

Seeing case = role

The point of running ONE word through everything is to break the habit of memorizing endings as a meaningless list. The ending is a label that tells the listener what this magazine, this school, is doing in the sentence. Russian word order is famously flexible precisely because the endings carry the roles — you could reorder the words and the listener would still know who's reading what, because журна́лом means "by means of the magazine" no matter where it sits.

Once you've watched журна́л and шко́ла make this journey, do it yourself with a noun you care about — your own name for a city, a food, a hobby. Build six little sentences. That five-minute exercise teaches more than re-reading the table a tenth time.

Common Mistakes

Key Takeaways

• The deep lesson is case = role: the same noun (журна́л, шко́ла) changes its ending to mark what it's doing in the sentence — subject, object, "of," recipient, means, topic.
• журна́л runs журна́л / журна́л / журна́ла / журна́лу / журна́лом / журна́ле; шко́ла runs шко́ла / шко́лу / шко́лы / шко́ле / шко́лой / шко́ле.
• Some forms coincide and you just can't see the case: masculine inanimate nouns merge nominative = accusative (журна́л); feminine -а nouns merge dative = prepositional (шко́ле).
• The two distinguishing feminine endings to remember are the -у accusative (шко́лу) and the -ой instrumental (шко́лой), against the masculine -ом (журна́лом).
• Endings carry the roles, which is why Russian word order is free — see case and free word order. For the full grid, see the master table of case endings; to pick a case while composing, see the decision guide.
