Nominative Case in Russian

In Brief

The Russian nominative case (именительный падеж) is the basic form used to name a person or thing and to mark the subject—the person or thing the sentence is about. It answers кто? “who?” and что? “what?”: Брат дома “My brother is at home”; Книга новая “The book is new.” For a singular noun, this is normally the form shown as the headword in a dictionary.

Overview

Russian nouns, pronouns, adjectives, and some numbers change form according to their role in a sentence. Each group of related forms is called a case. The nominative is the starting case: it labels someone or something, and it usually marks the subject (the person or thing that performs an action, experiences a state, or is being described).

This is one of the first A1 topics because every Russian sentence has to be understood in terms of roles. In English, word order does much of that work. Russian also uses word order, but case endings are crucial. Compare Мама любит Анну “Mom loves Anna” with Анна любит маму “Anna loves Mom.” The nominative forms мама and Анна identify the subject; the changed forms Анну and маму mark the direct object.

The beginner rule is simple: use the dictionary form for a singular subject and after common identification patterns such as это “this is.” However, “nominative” does not mean that a word can never change. Plural nouns have nominative plural forms, and adjectives change to agree with the noun’s gender and number.

How It Works

1. The nominative names the subject

Ask who or what performs the action or has the stated quality:

• Студент читает. — The student is reading. Who is reading? студент.
• Телефон работает. — The phone works. What works? телефон.
• Дети спят. — The children are sleeping. Who is sleeping? дети.

The subject does not have to be an active “doer.” In Окно открыто “The window is open,” окно is still the subject because the sentence states something about it.

Russian word order is flexible, so the subject is not always the first word:

• На столе лежит книга. — A book is lying on the table.
• Сегодня работает Анна. — Anna is working today.

Here книга and Анна remain nominative even though they occur later in the sentence.

2. Singular nominative forms and noun gender

The nominative singular is normally the dictionary headword. Its ending often helps identify the noun’s gender, a grammatical class that controls agreement.

Typical ending	Usual gender	Examples
consonant, -й	masculine	брат, музей
-а, -я	feminine	книга, неделя
-о, -е	neuter	окно, море
-ь	masculine or feminine; learn individually	словарь, дверь

Natural gender can override the usual ending: папа “dad” and дедушка “grandfather” end in -а/-я patterns but are masculine. This matters because accompanying adjectives and pronouns are masculine: мой папа, добрый дедушка.

3. Nominative plural is still nominative

Number and case are separate. A plural subject is nominative plural, but its ending differs from the singular dictionary form.

Singular	Plural	English
студент	студенты	student / students
книга	книги	book / books
окно	окна	window / windows
море	моря	sea / seas
брат	братья	brother / brothers

Plural formation has several patterns and irregular forms. At this stage, learn each common plural with its singular rather than trying to derive every form from one rule.

4. Adjectives and possessives agree

An adjective (a describing word) and a possessive such as “my” take endings that match the nominative noun’s gender and number.

Form	Typical adjective ending	“my”	Example
masculine singular	-ый, -ий, -ой	мой	новый словарь
feminine singular	-ая, -яя	моя	новая книга
neuter singular	-ое, -ее	моё	новое окно
plural	-ые, -ие	мои	новые книги

The agreement appears both inside a noun phrase and in a description:

• Это новая книга. — This is a new book.
• Книга новая. — The book is new.
• Окна большие. — The windows are large.

5. Identification with это

Use это to identify or point out a person or thing. In this pattern, это stays unchanged, while the noun naming the person or thing is nominative:

• Это мой брат. — This is my brother.
• Это моя сестра. — This is my sister.
• Это наше окно. — This is our window.
• Это мои друзья. — These are my friends.

Do not change это to match the following noun in this identifying construction. By contrast, этот, эта, это, эти mean “this/these” before a noun and do agree: этот брат, эта книга, это окно, эти книги.

6. Descriptions and predicate nouns in the present tense

Russian usually omits the present-tense equivalent of English “am/is/are.” A noun or adjective that identifies or describes the subject can therefore follow directly:

• Москва — большой город. — Moscow is a big city.
• Анна — врач. — Anna is a doctor.
• Моя сестра занята. — My sister is busy.

A noun that renames or classifies the subject in this pattern is a predicate noun—a noun that says what the subject is. At beginner level, it is normally nominative in present-tense definitions and identifications. In writing, a dash is commonly placed between two noun phrases, especially when both sides are nouns. No dash is normally needed before a simple adjective: Город большой.

7. Questions with кто? and что?

The nominative question words are:

• Кто? — who? (people and other animate beings)
• Что? — what? (things, ideas, and events)

Use them when asking for the identity of the subject or of something being presented:

• Кто это? — Это Олег. — Who is this? — This is Oleg.
• Что это? — Это словарь. — What is this? — It is a dictionary.
• Кто работает сегодня? — Мария. — Who is working today? — Maria.

Other cases have changed question forms, such as кого? “whom/of whom.” Choosing кто? or что? is therefore a useful test, but the sentence’s meaning and structure remain more reliable than simply matching a question word.

8. The thing possessed after у ... есть

In the common possession pattern у + person + есть, the thing that exists or is available is normally nominative:

• У меня есть машина. — I have a car.
• У нас есть дети. — We have children.

Literally, the structure is closer to “At me/us there is/are...” The owner after у is not nominative, but машина and дети are. This differs from English “I have...,” where “I” is the subject.

Common Mistakes

Changing a singular subject as if it were an object

• Wrong: Книгу лежит на столе.
• Right: Книга лежит на столе.
• Why: The book is what lies on the table, so it is the subject and must be nominative. Книгу is an accusative form used in a sentence such as Я читаю книгу “I am reading a book.”

Treating the first noun as the subject automatically

• Wrong interpretation: In Маму любит Анна, assuming маму means “Mom” is the subject because it comes first.
• Right: Маму любит Анна means “Anna loves Mom.”
• Why: Анна is nominative; маму has the accusative ending -у. Russian can move the object forward for emphasis.

Making identification это agree with the noun

• Wrong: Эта моя сестра when you mean “This is my sister.”
• Right: Это моя сестра.
• Why: Identifying это is fixed. Эта is used directly with a feminine noun: эта сестра “this sister.”

Forgetting adjective agreement

• Wrong: новый книга; моя брат
• Right: новая книга; мой брат
• Why: A nominative adjective or possessive must match the noun’s gender and number.

Inserting present-tense “is”

• Wrong: Москва есть большой город.
• Right: Москва — большой город.
• Why: Neutral modern Russian normally has no spoken equivalent of “is” in this kind of present-tense statement. Есть has other uses, especially existence and availability; it is not inserted wherever English uses “is.”

Assuming every dictionary-looking form is nominative in the sentence

• Wrong reasoning: стол must always be nominative because it looks like the dictionary form.
• Right: Determine its role from the whole sentence.
• Why: Some case forms look identical. In Я вижу стол “I see the table,” стол is accusative even though an inanimate masculine accusative has the same visible form as the nominative.

Usage Notes

Russian often leaves out a subject pronoun when the verb or context makes the subject clear: Работаю дома “I work at home.” The understood subject is still part of the sentence’s meaning, but no nominative word is spoken. Unlike English, Russian does not require an explicit “I,” “you,” or “we” in every complete sentence.

Word order changes emphasis more readily than it changes grammatical roles. Книга лежит на столе neutrally starts with “the book.” На столе лежит книга introduces what is on the table and may be translated naturally as “There is a book on the table.” The endings, not position alone, help identify книга as nominative.

Russian has no indefinite or definite articles corresponding exactly to English “a/an” and “the.” Depending on context, Это книга can mean “This is a book,” while Книга на столе can mean “The book is on the table.” Do not try to add a separate Russian word for every English article.

Beyond the Basics: Later Uses and Contrasts

You do not need to master the following points at A1, but they explain forms you will encounter later.

Nominative versus instrumental with быть

Present-tense definitions often use the nominative with no copula: Анна — врач “Anna is a doctor.” With быть “to be” in the past or future, a profession, role, or temporary capacity is commonly put in the instrumental case:

• Анна была врачом. — Anna was a doctor.
• Анна будет врачом. — Anna will be a doctor.

Nominative predicates can also occur in some past-tense contexts, especially for classification, identity, or a permanent-seeming property, and style affects the choice. The safe beginner contrast is: present definition, usually nominative; explicit past or future быть, expect to learn the instrumental.

Existence and negation

An affirmative existential sentence often has a nominative noun:

• В городе есть театр. — There is a theater in the city.

Under negation, Russian commonly uses the genitive instead:

• В городе нет театра. — There is no theater in the city.

This is an important reason not to think of the nominative as simply “the unchanged noun.” Meaning and construction determine case.

Quantities can control a different form

After many numbers and quantity words, the noun is not nominative even when the whole quantity phrase functions as the subject: Два студента пришли “Two students arrived”; Много людей пришло “Many people came.” The internal noun forms belong to the rules for numerals and the genitive case.

Names, labels, and forms of address

Titles, headings, signs, and labels often use the nominative because they simply name something: Ресторан «Москва», Станция «Парк культуры». Standard Russian also commonly uses the nominative when addressing someone: Анна, привет! “Hi, Anna!” In informal speech, shortened “new vocative” forms such as Маш! or мам! occur, but these are colloquial address forms, not the basic nominative pattern.

Ambiguous endings

Cases are grammatical roles, not always visibly different endings. Inanimate masculine nouns have identical nominative and accusative singular forms; many neuter nouns do too. Nominative and accusative plural can also coincide for inanimate nouns. Use the verb, agreement, animacy, and context together rather than judging from one ending.

Practice Tips

1. Ask who or what the sentence is about. In each short sentence, underline the subject and ask кто? or что? Then check that its adjectives and possessives agree.
2. Build four-part sets. Practice one phrase across masculine, feminine, neuter, and plural: новый дом, новая книга, новое окно, новые дома. This connects nominative case with gender and number.
3. Contrast subject and object pairs. Say Анна видит маму and Мама видит Анну, then swap the word order without losing track of the endings. This trains you not to rely on the English habit that the first noun is normally the subject.

Related Concepts

• Prerequisite: Noun Gender — gender determines the nominative agreement forms used with nouns.
• Next step: Accusative Case — contrasts the subject with the direct object and introduces direction with в and на.
