Nominative: The Dictionary Form and Subject

The nominative (имени́тельный паде́ж, imenítel'nyj padézh) is where every noun lives when it is at rest. It is the form printed in the dictionary, the form by which you tell a noun's gender, and the case of the grammatical subject — the person or thing doing the action. Among the six cases it is the "zero" case: not because it is empty, but because it is the base you build the other five from. Learn to recognize the nominative cleanly and you have a fixed point of reference for the whole case system. This page covers its two everyday jobs — naming/looking-up and being the subject — plus the one feature that surprises English speakers most: in the present tense, the bare nominative can be a whole sentence, because there is no verb "to be" to insert.

The nominative is the dictionary form

When you look a noun up — стол, кни́га, окно́ — what you find is its nominative singular. This is the citation form, the one in which words are listed, taught, and counted. Crucially, it is also the form that predicts grammatical gender by its ending:

Nominative ends in…	Usually gender	Example
a consonant (or -й)	masculine	стол (table), геро́й (hero)
-а / -я	feminine	кни́га (book), неде́ля (week)
-о / -е	neuter	окно́ (window), мо́ре (sea)

This is exactly why gender is read off the nominative and nowhere else — once the noun shifts into another case, the ending no longer signals gender. (The full picture, including the tricky -ь nouns, is on noun gender.)

Э́то сло́во — существи́тельное же́нского ро́да.

This word is a feminine noun. — кни́га is listed in the dictionary in the nominative, and its -а marks it feminine.

The nominative is the subject

The headline job: the nominative marks the subject — the doer of the verb. It answers the question кто? ("who?") for people and animals and что? ("what?") for things. If you can ask "кто/что [does the verb]?" and the noun is the answer, that noun is in the nominative.

Студе́нт чита́ет.

The student is reading. — Кто чита́ет? Студе́нт. — nominative subject.

Соба́ка спит на дива́не.

The dog is sleeping on the sofa. — Кто спит? Соба́ка. — nominative subject.

Кни́га лежи́т на столе́.

The book is lying on the table. — Что лежи́т? Кни́га. — nominative subject (a thing, so что?).

The subject also controls agreement: the verb matches the subject in number (and, in the past tense, gender), and any adjective describing the subject sits in the nominative too. So in Но́вая маши́на стои́т до́рого ("A new car costs a lot"), но́вая and маши́на are both nominative, and the verb стои́т is third-person singular to match.

Мои́ роди́тели живу́т в Москве́.

My parents live in Moscow. — роди́тели (nom. pl. subject) drives the plural verb живу́т.

💡

The quickest test for the nominative is the question кто? or что?. Ask "who/what is doing this?" — the answer is your subject, and it must be nominative. This is the same instinct you already use in English to choose he over him as the subject: he reads, not him reads.

Subject vs object: the minimal pair

Because the nominative is the subject, it stands in direct contrast with the accusative, the case of the direct object. Watching one noun switch between the two is the cleanest way to feel what "case marks role" means. Take сестра́ ("sister"):

Сестра́ зовёт ма́му.

The sister is calling Mum. — сестра́ (nom., the caller) vs ма́му (acc., the one called).

Сестру́ зовёт ма́ма.

Mum is calling the sister. — now ма́ма is the nominative caller and сестру́ the accusative object; the -у ending, not the order, flips the roles.

The endings carry the meaning: -а marks сестра́ as the subject, -у marks сестру́ as the object. Word order is free precisely because of this, which is the whole point of the case system — covered on the overview. The accusative side of this contrast is on the direct object.

The big one: no "to be" in the present tense

Here is the feature that trips up nearly every English speaker. In the present tense, Russian has no verb "to be." There is no word standing in for am / is / are. So a sentence like "He is a student" is simply two nouns/pronouns side by side, both in the nominative, with nothing between them:

Он студе́нт.

He is a student. — literally 'He student'; both Он and студе́нт are nominative, and there is NO verb.

Я учи́тель.

I am a teacher. — 'I teacher'; the bare nominative предикат IS the sentence.

Москва́ — столи́ца.

Moscow is the capital. — 'Moscow — capital'; in writing a dash often replaces the missing verb.

The noun after the (absent) verb — the predicate noun — also sits in the nominative. So both halves of Он студе́нт are nominative: Он as subject, студе́нт as predicate. There is nothing to conjugate and nothing to insert. The most common beginner reflex is to reach for a copula — to translate is with есть or to try to conjugate быть ("to be") — and you must resist it. In the present, the gap is correct.

💡

Do not insert есть or any form of быть into a plain present-tense "X is Y" sentence. Он есть студе́нт is wrong; Он студе́нт is right. (есть does survive in a few special meanings — "there is/exists" and in possession У меня́ есть… — but not as the everyday copula. The verb быть as such only resurfaces in the past and future: Он был студе́нтом. See быть.)

The past and future do use быть (был / бу́дет), and there the predicate noun typically shifts into the instrumental, not the nominative: Он был студе́нтом ("He was a student"). That contrast — nominative predicate in the present vs instrumental predicate in the past/future — is the subject of nominative in predicates and the instrumental pages; for now, just hold onto the present-tense rule: bare nominative, no verb.

Это plus the nominative

A second place the nominative shows up early is after это ("this is / it is / these are"). это is an invariable pointer — it does not change for gender or number — and the noun it introduces stands in the nominative:

Э́то дом.

This is a house. — это points; дом is nominative.

Э́то моя́ ма́ма.

This is my mum. — это + nominative моя́ ма́ма.

Что э́то? — Э́то слова́рь.

What is this? — It's a dictionary. — both the question (что?) and the answer (слова́рь) are nominative.

Note that это here is the presentational word, distinct from the demonstrative э́тот/э́та/э́то ("this [noun]") that agrees with its noun. The presentational это is frozen; the complement after it is nominative. This and the question words кто?/что? get fuller treatment on asking who, what, this.

Common Mistakes

❌ Он есть студе́нт.

Incorrect — Russian has no present-tense copula; do not insert есть as 'is'.

✅ Он студе́нт.

He is a student. — bare nominative predicate, no verb.

❌ Я зову́ сестра́.

Incorrect — the object of звать is accusative; here the subject role (nominative сестра́) was wrongly used for the object.

✅ Я зову́ сестру́.

I'm calling my sister. — accusative сестру́ for the object; the subject is Я.

❌ Э́то моего́ бра́та.

Incorrect — after это the complement is nominative, not genitive/accusative.

✅ Э́то мой брат.

This is my brother. — nominative мой брат after это.

❌ Looking up столе́ in the dictionary and not finding it.

Incorrect approach — столе́ is the prepositional form; nouns are listed only in the nominative.

✅ Look up стол.

The dictionary (nominative) form. Reduce any case form back to the nominative to find the entry.

Key Takeaways

The nominative (имени́тельный паде́ж) is the dictionary/base form and the case of the subject — the doer.
It answers кто? (who?) for people/animals and что? (what?) for things, and it controls verb and adjective agreement.
Its ending predicts gender (consonant → m., -а/-я → f., -о/-е → n.), which is why gender is read only off the nominative.
Subject (nominative) contrasts with object (accusative): Сестра́ зовёт ма́му vs Сестру́ зовёт ма́ма — the ending, not the order, sets the roles.
In the present tense there is no verb "to be": the predicate noun simply sits in the nominative with no copula (Он студе́нт, Я учи́тель, Москва́ — столи́ца). Never insert есть. The same applies after это (Это дом).
