Gender & Nouns
In a nutshell
- Every Russian noun has a grammatical gender: masculine, feminine, or neuter. You can usually tell from the last letter.
- Nouns ending in ь are ambiguous — could be masculine or feminine, and you have to memorize which.
- A few nouns are grammatically feminine-looking but refer to people who are naturally male (папа, дедушка) — natural gender wins.
- Plurals mostly follow -ы/-и (and -а/-я for neuter), but there's a spelling rule and a short list of common irregulars you need to just know.
Gender is the foundation everything else sits on. Every case ending you'll learn in the next five lessons depends on a noun's gender — so getting this automatic now saves you from re-learning it five times over.
How to tell gender from the ending
Look at the last letter of the dictionary (nominative singular) form.
| Ending | Gender | Examples |
|---|---|---|
| consonant | masculine | стол (table), дом (house), студе́нт (student) |
| -а / -я | feminine | кни́га (book), маши́на (car), неде́ля (week) |
| -о / -е | neuter | окно́ (window), мо́ре (sea) |
| -ь | ambiguous — masc. or fem. | see below |
For roughly 90% of nouns, this table is all you need: no ending → masculine, -а/-я → feminine, -о/-е → neuter.
The -ь problem
Nouns ending in a soft sign, ь, can be either masculine or feminine — the spelling doesn't tell you. You have to learn the gender with the word, the same way you'd learn the gender of a French or German noun.
| Word | Gender | Meaning |
|---|---|---|
| день | masculine | day |
| слова́рь | masculine | dictionary |
| учи́тель | masculine | teacher (male) |
| дверь | feminine | door |
| ночь | feminine | night |
| крова́ть | feminine | bed |
A rough (not perfect) tendency: -ь words for professions/roles and abstract "action" nouns skew masculine, while body-part and everyday-object -ь words skew feminine — but this is a tendency, not a rule. When you learn a new -ь noun, learn its gender at the same time, the way you'd note "der/die/das" for a German word.
Natural gender overrides spelling
A handful of nouns end in -а/-я (which normally signals feminine) but refer to male people. For these, natural gender wins — they behave grammatically as masculine.
| Word | Meaning | Behaves as |
|---|---|---|
| па́па | dad | masculine |
| де́душка | grandpa | masculine |
| дя́дя | uncle | masculine |
| мужчи́на | man | masculine |
Мой па́па до́ма. — lit. "My-MASC dad-NOM home." — "My dad is home."
Notice «мой» (my, masculine) rather than «моя́» (my, feminine) — because «па́па» refers to a man, everything that agrees with it uses masculine forms, even though the noun itself ends in -а like a feminine noun.
Plurals
The basic pattern
| Singular ending | Plural ending | Example |
|---|---|---|
| hard consonant (masc.) | -ы | стол → столы́ |
| soft consonant / -ь (masc.) | -и | слова́рь → словари́ |
| -а (fem.) | -ы | кни́га → кни́ги* |
| -я (fem.) | -и | неде́ля → неде́ли |
| -ь (fem.) | -и | дверь → две́ри |
| -о (neut.) | -а | окно́ → о́кна |
| -е (neut.) | -я | мо́ре → моря́ |
*«кни́га» → «кни́ги» looks like it breaks the -а→-ы pattern — that's the spelling rule below in action, not an exception to gender logic.
The 7-letter spelling rule
Russian spelling forbids writing ы after seven specific letters. If a plural ending would normally be -ы, but the noun's last consonant is one of these seven, you write -и instead:
After г, к, х, ж, ш, щ, ч — always write и, never ы.
| Word | Last consonant | Expected | Actually written |
|---|---|---|---|
| кни́га | г | книгы | кни́ги |
| студе́нтка | к | студентокы | студе́нтки |
| ру́чка | к | ручкы | ру́чки |
| нога́ | г | ногы | но́ги |
This same rule reaches beyond plurals — it's why «жить» and «маши́на» are spelled with и rather than ы even though ж and ш are hard consonants (see Alphabet & Pronunciation §5). One spelling rule, two places you'll see it. Memorize the seven letters as a group: г к х ж ш щ ч.
Common irregular plurals
These don't follow any ending pattern — just learn them as vocabulary, the way you learned "child → children" in English.
| Singular | Plural | Meaning |
|---|---|---|
| челове́к | лю́ди | person → people |
| ребёнок | де́ти | child → children |
| друг | друзья́ | friend → friends |
| брат | бра́тья | brother → brothers |
| сын | сыновья́ | son → sons |
| стул | сту́лья | chair → chairs |
| мать | ма́тери | mother → mothers |
| дочь | до́чери | daughter → daughters |
У меня́ есть друзья́. — lit. "At me exist friends-NOM." — "I have friends."
Note «друзья́» — not «дру́ги» — for the plural of «друг». This is exactly the kind of irregular you just have to drill until it's automatic.
Putting it together
Э́то большо́й стол. — lit. "This big-MASC table-NOM." — "This is a big table." (masc., no ending)
Э́то но́вая кни́га. — lit. "This new-FEM book-NOM." — "This is a new book." (fem., -а)
Э́то ста́рое окно́. — lit. "This old-NEUT window-NOM." — "This is an old window." (neut., -о)
The adjective endings agreeing with each gender (большо́й / но́вая / ста́рое) are covered in full in Adjectives & Possessives — for now just notice that gender ripples outward from the noun to everything describing it. That's why nailing gender now pays off in every lesson from here on, starting with Accusative.
Practice
Try each one before checking the answer.
- Give the gender of: стол, ко́мната, окно́, слова́рь, ночь, па́па.
- Give the gender of: неде́ля, дом, мо́ре, дверь, дя́дя, кни́га.
- Form the plural of: студе́нт, кни́га, окно́, ру́чка.
- Form the plural of: мо́ре, стол, неде́ля, нога́.
- Give the irregular plural of: ребёнок, челове́к, друг, брат.
- Why is «кни́ги» spelled with и rather than ы?
- Explain why «мой де́душка» uses «мой» (masculine) even though «де́душка» ends in -а.
- Translate: "This is my friend (m.)." (use «мой друг»)
- Translate: "I have children." (use «у меня́ есть»)
- Sort these into masc./fem./neut.: тетра́дь, письмо́, музе́й, семья́, у́тро.
Answers
- стол — masc. (consonant ending); ко́мната — fem. (-а); окно́ — neut. (-о); слова́рь — masc. (-ь, learned as masculine); ночь — fem. (-ь, learned as feminine); па́па — masc. (natural gender overrides the -а ending).
- неде́ля — fem. (-я); дом — masc. (consonant); мо́ре — neut. (-е); дверь — fem. (-ь, learned as feminine); дя́дя — masc. (natural gender); кни́га — fem. (-а).
- студе́нт → студе́нты (masc. consonant → -ы); кни́га → кни́ги (spelling rule: г blocks ы, use и); окно́ → о́кна (neut. -о → -а); ру́чка → ру́чки (spelling rule: к blocks ы, use и).
- мо́ре → моря́ (neut. -е → -я); стол → столы́ (masc. consonant → -ы, no spelling-rule letter involved); неде́ля → неде́ли (fem. -я → -и); нога́ → но́ги (spelling rule: г blocks ы, use и).
- ребёнок → де́ти; челове́к → лю́ди; друг → друзья́; брат → бра́тья. All four are memorized irregulars, not pattern-based.
- Because г is one of the seven letters (г к х ж ш щ ч) after which ы can never be written — и is substituted automatically, regardless of gender logic.
- «Де́душка» ends in -а (grammatically feminine-looking) but refers to a man — natural gender overrides the spelling, so everything agreeing with it (мой, not моя́) takes masculine form.
- Э́то мой друг. — lit. "This my-MASC friend-NOM." — "This is my friend."
- У меня́ есть де́ти. — lit. "At me exist children-NOM." — "I have children." (де́ти is the irregular plural of ребёнок)
- тетра́дь — fem. (-ь, learned as feminine, "notebook"); письмо́ — neut. (-о, "letter"); музе́й — masc. (ends in the consonant-like й, "museum"); семья́ — fem. (-я, "family"); у́тро — neut. (-о, "morning").
