Nominative Имени́тельный паде́ж Кто? Что?. Who? What?

Core Uses

Subject of the sentence, the one doing the action
Predicate noun after быть (to be), "He is a soldier"
Dictionary form, what you look up

Memory Hook

This is the base form. No ending changes from the dictionary. If you can't remember a case, nominative is your fallback, it won't always be right but it won't confuse a native speaker completely.

Think of it as the noun standing up straight, announcing itself: "I am the subject."

Common Endings

Gender	Singular	Plural
Masculine	, (consonant) / -й / -ь	-ы / -и
Feminine	-а / -я / -ь	-ы / -и
Neuter	-о / -е	-а / -я

Military Examples

Солда́т бежи́т. The soldier is running. солда́т = subject

Вертолёт лети́т на се́вер. The helicopter is flying north. вертолёт = subject

Команди́р здесь. The commander is here. predicate position, no verb needed

Враг в дере́вне. The enemy is in the village. враг = subject

Accusative Вини́тельный паде́ж Кого́? Что?. Whom? What?

Core Uses

Direct object, receives the action of the verb
Direction / destination with в and на
Duration of time ("for three hours")

Memory Hook

Inanimate nouns: look identical to Nominative for masculine and neuter. Only feminine changes (-а → -у, -я → -ю).

Animate nouns (people, animals): masculine changes to match Genitive (-а / -я). Think "alive = care more about it = different ending."

Rule of thumb: if you can replace the noun with "him/her/it" in English, it's accusative.

Common Endings

Gender	Inanimate Sg.	Animate Sg.	Plural
Masculine	= Nominative	-а / -я (= Gen.)	= Gen. Plural
Feminine	-у / -ю	-у / -ю	= Gen. Plural
Neuter	= Nominative	= Nominative	= Gen. Plural

Military Examples

Е́дем в ба́зу. We're driving to base. в + accusative = destination/direction

Вызыва́ю команди́ра. I'm calling the commander. команди́р (animate masc.) → команди́ра

Я ви́жу маши́ну. I see the vehicle. маши́на (inanimate fem.) → маши́ну

Иди́ на пози́цию. Move to the position. на + accusative = direction toward

Genitive Роди́тельный паде́ж Кого́? Чего́?. Of whom? Of what?

Core Uses

Possession / "of", "the commander's rifle" / "rifle of the commander"
Absence with нет, "there is no…"
After numbers 2–4 (singular gen.) and 5+ (plural gen.)
After quantity words: мно́го, ма́ло, не́сколько
After prepositions: у, из, от, без, до, по́сле, для, о́коло
Negation, making a verb negative often triggers genitive

Memory Hook

Genitive is the most common non-nominative case, learn it first and you'll unlock a huge amount of Russian.

The "of" trick: mentally insert "of" between two nouns. "Автома́т of the soldier" → солда́та in genitive.

Нет + genitive = absence. "У меня́ нет патро́нов". I have no ammunition. The thing that doesn't exist goes genitive.

Common Endings

Gender	Singular	Plural
Masculine	-а / -я	-ов / -ев / -ей /.
Feminine	-ы / -и	, / -ей
Neuter	-а / -я	, / -ей

Military Examples

With к (toward a person or place)
Experiencer constructions, "мне хо́лодно" (I am cold)
Age, "мне два́дцать лет" (I am twenty)
With по (along, according to, by)

Memory Hook

Dative is the "to/for" case. Any time you're giving, sending, saying, showing, or reporting something TO someone, that someone is dative.

Also remember: к + dative = moving toward a person. "Иду́ к команди́ру", going to (toward) the commander. Contrast with в/на + accusative which are destinations (places).

Common Endings

Gender	Singular	Plural
Masculine	-у / -ю	-ам / -ям
Feminine	-е / -и	-ам / -ям
Neuter	-у / -ю	-ам / -ям

Mode of travel, "е́дем маши́ной" (traveling by car)

Memory Hook

Think "instrument", what you're using. Стреля́ю автома́том, shooting with/by means of a rifle. The ending -ом / -ей / -ью is very recognizable once you see it a few times.

С + instrumental = together with. "С команди́ром" = with the commander. Don't confuse with из (out of, genitive), с means companionship or joint action.

Common Endings

Gender	Singular	Plural
Masculine	-ом / -ем	-ами / -ями
Feminine	-ой / -ей / -ью	-ами / -ями
Neuter	-ом / -ем	-ами / -ями

Memory Hook

The key contrast: в/на + accusative = motion toward. в/на + prepositional = static location.

"Е́дем в дере́вню" (we're going TO the village, accusative direction) vs "Мы в дере́вне" (we ARE in the village, prepositional location). Same preposition, totally different meaning based on case.

Endings are some of the most consistent in Russian: mostly -е for singular across all genders.

Feminine	-е / -и	-ах / -ях
