In Russian the Instrumental is the case of "tools and professions." While it is frequently used with the preposition с (with), many of the most important verbs in Russian demand the Instrumental case without any preposition at all.

When to use Instrumental

Here is the overview of when to use the Instrumental case:

ContextExample
Tool/Instrument - I write with a pencil.
Preposition с (with) - with a friend
Profession - to be a teacher
Season of year
Time of day
- It's cold in winter.
- It's cold in the morning.
Some spatial prepositions
- under the table
- above the sofa
- behind the cloud
- in front of the house
- between mom and dad
- next to the bank
Some advanced verbs
see below
for hobbies
for management and control
for emotions and attitudes
Passive agent - Made by a robot
Route - To drive through/via the field

1. Instruments and Means (The "Tool" Use)

This is the most literal use of the case. When you use an object to perform an action, that object goes into the Instrumental.

  • - I write with a pencil.
  • - We eat soup with a spoon.
  • - He arrived by train.

2. Preposition с - with

с is the most common preposition for the Instrumental case. It indicates accompaniment or "togetherness."

Examples:

  • - Coffee with milk.
  • - I am going to the cinema with a friend.

Important: Do not use "с" when you are using a tool. Correct: Я пишу́ ру́чкой. - I write with/using a pen - no preposition. Wrong: Я пишу́ с ру́чкой. - I am writing together with my pen - as if it's your companion.

3. Identity, Status, and Professions

These are the most frequent verbs. Use the Instrumental to describe what someone is, becomes, or works as.

VerbExample
быть
to be

He wants to be a doctor.
станови́ться / стать
to become

She became an actress.
рабо́тать / порабо́тать
to work as

I work as an engineer.
явля́ться / яви́ться
to be - formal

This is [constitutes] a problem.
каза́ться / показа́ться
to seem

He seems like a smart person.

4. Time and Seasons

When describing parts of the day or seasons as a general timeframe (answering "When?"), use the Instrumental.

Seasons:

  • - in summer
  • - in winter
  • - in autumn
  • - in spring

- In winter we often ski.

Times of day:

  • - in the morning
  • - during the day
  • - in the evening
  • - at night

- In the morning I drink coffee.

5. Some spatial prepositions

These prepositions answer the question где? (where?). But note that the most important spatial preposition is в (in) and takes prepositional, not instrumental.

PrepositionExample
под
under

under the table
над
above

above the sofa
за
behind

behind the cloud
пе́ред
in front of

in front of the house
ме́жду
between

between mom and dad

A few of these, specifically за (behind) and под (under), can take either the Accusative or the Instrumental depending on whether there is movement.
Example for movement, using Accusative: Я кладу́ кни́гу под стол. - I put the book under the table.
Example for static location, using Instrumental: Кни́га лежи́т под столо́м. - The book is under the table.

6. Verbs

Some advanced verbs demand the Instrumental case.

Verbs for Interests and Activities

VerbExample
занима́ться / заня́ться
to do / to study / to practice

We do sports.
интересова́ться / заинтересова́ться
to be interested in

I'm interested in history.
увлека́ться / увле́чься
to be keen on / fond of

She is into music.
по́льзоваться / воспо́льзоваться
to use / to make use of

He uses a computer.

Verbs for Management and Control

VerbExample
управля́ть
to manage / to drive

Who manages the company?
руководи́ть
to lead / to direct

He leads the department.
кома́ндовать
to command

The general commands the army.
владе́ть
to own / to master a language

Do you have command of the Russian language?

Verbs for Emotions and Attitudes

VerbExample
горди́ться
to be proud of

We are proud of our son.
восхища́ться / восхити́ться
to admire / be delighted by

I admire your talent.
же́ртвовать / поже́ртвовать
to sacrifice

He sacrificed his career.

7. Passive Voice (The Agent)

In passive constructions, the person or thing performing the action is put into the Instrumental case.

Active: - Pushkin wrote this poem.

Passive: - This poem was written by Pushkin.

Note that Russian uses the passive much less than English: in everyday speech an active sentence is usually preferred, and the participle passive shown here belongs mostly to formal and written Russian (news, documents, science). For all the details see the passive voice article.

8. Using with routes

When the Instrumental case is used for a route, it describes the space or path through which an action moves. In English, we usually express this as "by," "through," "via," or "along."

This usage is unique because it doesn't require a preposition like "through" (че́рез). The noun itself, in its Instrumental form, acts as the path.

Common Spatial Routes

You use this when movement occurs across or through a specific type of terrain.

RouteExample
по́лем
through/via the field

We walked through the field.
ле́сом
through/via the forest

The path goes through the forest.
бе́регом
along the shore

They strolled along the riverbank.
доро́гой
by way of the road

Let's go by/via a different road.

Using "Parts" of a Route

It is often used to describe moving through specific architectural or geographical features.

RouteExample
коридо́ром
through the corridor

He walked through the long corridor.
ле́стницей
via the stairs

Go up via the back stairs.

Abstract or "Method" Routes

Sometimes the "route" isn't a physical path, but a method of travel or a metaphorical direction.

RouteExample
во́здухом
by air

The cargo was sent by air.
мо́рем
by sea

The cargo was sent by sea.
путём
by way of

We solved the problem by peaceful means/way.

While you can use prepositions like че́рез (through) or по (along), the Instrumental case on its own often sounds more poetic or natural for "wandering" or "following a path".
Route: Шли ле́сом (focus on the path itself) vs Шли че́рез лес (focus on entering/exiting).
Surface: Е́хали по́лем (moving across the expanse) vs Е́хали по по́лю (moving along the surface).

A common idiom: Literally: Go through the forest! Actual meaning: "Get lost!" or "Go away!".

11. Some fixed expressions

- Happy New Year! - literally "With the New Year!"

- by the way / incidentally

- before sleep/bedtime
