Subject Pronouns (Nominative)

Russian has 8 personal pronouns in the nominative case (subject form). Unlike English, Russian distinguishes between informal "you" (ты — one person you know well) and formal/plural "you" (вы — polite address or multiple people). The formal вы is always capitalized in writing when addressing one person politely (Вы).

RussianPronunciationEnglishNotes
яyaI
тыtyyou (informal)One person — friends, family, children
онonhe / it (masc.)Also used for masculine nouns
онаa-NAshe / it (fem.)Also used for feminine nouns
оноa-NOit (neuter)Used for neuter nouns
мыmywe
выvyyou (formal / plural)Capitalized as Вы for polite singular
ониa-NItheyFor all genders
Tip: The ты/вы distinction is important socially. Using ты with a stranger or someone older can be rude. When in doubt, use вы. Russians often explicitly suggest switching to ты: "Давай на ты?" (Shall we use ты?).

Full Declension Table

Personal pronouns decline across all six cases. This is the most important pronoun table in Russian — you will use these forms constantly. Unlike nouns, pronoun forms are irregular and must be memorized individually.

Я вижу его. Он говорит мне. Она идёт с нами.I see him. (accusative) He is telling me. (dative) She is going with us. (instrumental)
Tip: Notice the patterns: genitive and accusative forms are identical for all pronouns. For я and ты, dative and prepositional are also the same (мне/мне, тебе/тебе). These overlaps make memorization easier.

The Prepositional Н- Rule

When third-person pronouns (он, она, оно, они) are used after a preposition, they gain an н- prefix. This only affects the oblique cases (not nominative). First- and second-person pronouns (я, ты, мы, вы) are never affected.

Without PrepositionWith PrepositionExample
его (his/him)у негоУ него есть книга. (He has a book.)
ему (to him)к немуЯ иду к нему. (I am going to him.)
им (with him)с нимЯ говорю с ним. (I am talking with him.)
ей (to her)к нейЯ иду к ней. (I am going to her.)
ей (with her)с нейЯ говорю с ней. (I am talking with her.)
её (her)у неёУ неё есть кошка. (She has a cat.)
им (to them)к нимМы идём к ним. (We are going to them.)
их (them)у нихУ них большой дом. (They have a big house.)
Это его книга. Я взял книгу у него.This is his book. (possessive — no preposition, no н-) I took the book from him. (preposition у — requires н-)
Tip: The н- rule only applies after actual prepositions (у, к, с, в, на, о, etc.). It does NOT apply when его/её/их are used as possessives: "его книга" (his book — no н-) but "у него" (at his place — with н-). This distinction matters!

Reflexive Pronoun себя

Russian has a special reflexive pronoun себя meaning "oneself." It refers back to the subject of the sentence, regardless of person, gender, or number. It has no nominative form — you cannot use it as a subject. Declension: Genitive — себя, Dative — себе, Accusative — себя, Instrumental — собой, Prepositional — себе.

CaseFormExampleTranslation
GenitiveсебяОна не помнит себя в детстве.She doesn't remember herself in childhood.
DativeсебеОн купил себе книгу.He bought himself a book.
AccusativeсебяОна видит себя в зеркале.She sees herself in the mirror.
InstrumentalсобойВозьми зонт с собой.Take an umbrella with you(rself).
PrepositionalсебеОн думает о себе.He thinks about himself.
Я купил себе подарок. Она довольна собой.I bought myself a present. She is pleased with herself.
Tip: себя always refers back to the subject: "Я купил себе" (I bought for myself), "Ты купил себе" (you bought for yourself), "Он купил себе" (he bought for himself) — the form себе never changes. The common phrase "Чувствуйте себя как дома" means "Make yourself at home."
