Russian Names Explained: First Name, Patronymic, Surname (and How They Decline)

Official documents, school registers, and formal introductions all use three parts: имя (first name), отчество (patronymic, from the father’s first name), and фамилия (surname). Together they identify a person the way a full legal name does in English — but the middle part is not a "middle name," it is generated from your father.

• The patronymic literally means "son of Иван" or "daughter of Иван" — Иванович / Ивановна.
• All three parts appear on a passport; only the first two are used in polite spoken address.
• Surnames are inherited from the family, like in English — they don’t depend on either parent’s first name.

Russians use short, affectionate forms constantly — with friends, family, and children the full name can even sound cold. Each first name has one or more standard nicknames.

• Nicknames are for informal ты contexts — never combine a nickname with a patronymic (no "Саша Иванович").
• Adding suffixes like -очка/-енька makes names even more affectionate: Машенька, Ванечка.
• For gender rules behind these endings, see the [noun gender guide](/learn/articles/russian-noun-gender-guide).

The patronymic is formed from the father’s first name plus a suffix that depends on gender: -ович / -евич for sons, -овна / -евна for daughters. Names ending in a soft consonant or vowel take a slightly different suffix.

• The patronymic is used together with the first name — Иван Иванович, not alone in most contexts.
• Among older generations, using the patronymic by itself (e.g., calling someone just "Ивановна") is a mark of familiar respect, common for older women in a village or workplace.
• You never choose your own patronymic — it comes automatically from your father’s name.

Unlike English surnames, most Russian surnames change form depending on whether they belong to a man or a woman — because many surnames are grammatically adjectives.

• Surnames ending in -ский/-ская decline exactly like adjectives — see the [adjective declension guide](/learn/articles/russian-adjective-declension).
• Surnames ending in -ов/-ев/-ин decline like nouns, with a few adjective-style endings mixed in (instrumental -ым).
• Some surnames are indeclinable: foreign-origin names and those ending in -ко, -их, -ых (e.g., Шевченко, Седых) never change, for any gender or case.

Choosing the right name form is as much about the relationship as the grammar. Mixing a nickname with вы, or a full name+patronymic with ты, sounds off to a Russian ear.

• When in doubt, default to Имя + Отчество + вы — it is never rude, only ever safe.
• Foreigners are often forgiven for skipping the patronymic, but attempting it is genuinely appreciated.
• Workplaces are shifting toward first-name-only address for younger staff — follow the room’s lead.

Names are nouns, so they take case endings like everything else in a Russian sentence. First names follow regular noun patterns; patronymics and adjective-type surnames combine noun and adjective endings.

• Я иду к Ивану ("I’m going to Ivan’s") uses the dative, just like any other noun after к.
• Я говорю об Ивановне ("I’m talking about Ivanovna") uses the prepositional after об.
• For the full pattern behind each case, see our [genitive](/learn/articles/russian-genitive-case), [dative](/learn/articles/russian-dative-case), and [prepositional](/learn/articles/russian-prepositional-case) guides.

A few habits give away a beginner immediately — and are easy to fix.

• Саша Иванович ✗ — never pair a nickname with a patronymic; use either Иван Иванович or just Ваня.
• Мария Ивановна for a woman whose father is Иван ✓ — but check gender: a father named Илья gives Ильинична, not "Ильевна".
• Forgetting that surnames like Достоевский must agree in gender: a woman is Достоевская, never "Достоевский".
• Using вы with a nickname ("Ваня, вы...") — pick one register: either full name + вы, or nickname + ты.
