Здравствуйте!
Welcome to a new module. In our last set of lessons, you learned how to build narratives by sequencing events in the past and future. Now, we're shifting our focus from when things happen to how they happen and who or what is involved. This means diving into one of the most powerful features of Russian grammar: the case system.
You've already encountered the nominative case (the basic dictionary form of a noun) and the accusative case (for direct objects). Today, we'll explore the instrumental case (твори́тельный паде́ж). As its name suggests, this case is used to describe the instrument or means by which an action is done. By the end of this lesson, you will be able to form the instrumental case of nouns, a skill that will unlock countless new ways to express yourself, from saying you draw "with a pencil" to talking about your hobbies.
1. What is the Instrumental Case?
The instrumental case primarily answers the questions "Чем?" (chem? - with what?) and "Кем?" (kem? - with whom?/by whom?). It's the "with" case.
Let's start with a practical demonstration. The following video explains and shows several key uses of the instrumental case. Pay close attention to how it's used to describe the instrument of an action.

In this video from the 'Easy Russian' channel, the host explains the instrumental case with clear, real-world examples. We'll focus on the core meaning of the case.
Watch the segment from 03:09 to 04:07. Notice how the speaker describes writing 'with a pen' (писа́ть ру́чкой) and stirring coffee 'with a spoon' (меша́ть ко́фе ло́жкой). In English, we need the word 'with'; in Russian, the noun ending itself does the job.
As you saw, saying "I write with a pen" doesn't require a preposition. The noun ру́чка (pen) changes to ру́чкой, and that new ending contains the meaning of "with". This is the essence of the instrumental case.
2. How to Form the Instrumental Case
To use the instrumental case, you need to change the ending of a noun based on its gender and its nominative (dictionary) form. Let's break down the rules.
The next video provides a systematic walkthrough of the endings for masculine, feminine, and neuter nouns.
Nouns in the Instrumental case
The 'Russian with Nastya' channel offers a great grammatical breakdown. This segment will give you the essential rules for forming the instrumental case for nouns.
Watch from 01:17 to 06:39. The instructor will present a table showing the nominative endings and how they change in the instrumental case. Have a notebook ready to jot down the patterns.
Let's summarize those rules.
Masculine Nouns:
- Ends in a consonant: add -ом
стол(table) →столо́мкомпью́тер(computer) →компью́тером
- Ends in -й or -ь: replace with -ем
музе́й(museum) →музе́емучи́тель(teacher) →учи́телем
Neuter Nouns:
- Ends in -о: replace with -ом
письмо́(letter) →письмо́м
- Ends in -е: replace with -ем
мо́ре(sea) →мо́рем
Feminine Nouns:
- Ends in -а: replace with -ой (or -ою)
кни́га(book) →кни́гойру́чка(pen) →ру́чкой
- Ends in -я: replace with -ей (or -ею)
земля́(earth) →землёй
- Ends in -ь (soft sign): add -ю
ночь(night) →но́чьюкисть(paintbrush) →ки́стью
3. Quick Reference and Practice
Having a clear chart is incredibly helpful. The image below provides a fantastic summary of the noun endings for the instrumental case. It also includes adjective endings, which we will cover in a later module, so focus on the top half (Nouns) for now.
For a more detailed document you can save for future reference, the "Self-Study Russian Online" page provides an excellent PDF summary.

4. Application: Talking About Your Hobbies
Now let's apply this grammar to something you're interested in. A very common way to talk about your hobbies is with the verb занима́ться (to be engaged in/to do), which requires the instrumental case. This is perfect for your interests in drawing and illustration.
Structure: Я занима́юсь + [hobby in Instrumental case]
Let's look at some examples relevant to you.
| Nominative (The hobby) | Instrumental (used with занима́ться) |
Example Sentence |
|---|---|---|
рисова́ние (drawing) |
рисова́нием |
Я занима́юсь рисова́нием. |
иллюстра́ция (illustration) |
иллюстра́цией |
Я занима́юсь иллюстра́цией. |
иску́сство (art) |
иску́сством |
Он занима́ется иску́сством. |
диза́йн (design) |
диза́йном |
Она́ занима́ется диза́йном. |
фотогра́фия (photography) |
фотогра́фией |
Мы занима́емся фотогра́фией. |
This structure is a powerful way to sound natural when discussing interests. The blog post below provides more great examples.

Great job today! You've tackled your third Russian case and learned the rules to form it correctly. This is a major step that opens up a huge range of expression.
Key Takeaways:
- The instrumental case is the "with" case, answering the questions "Чем?" (with what?) and "Кем?" (with whom?).
- Noun endings change based on their gender and nominative form.
- Masculine and neuter nouns typically take -ом or -ем.
- Feminine nouns typically take -ой, -ей, or add -ю to a soft sign.
- You can use the structure

Preview of the next lesson:
Now that you can form the instrumental case, we'll focus on its most common uses. In the next lesson, we will explore the preposition с (s), which means "with." You'll learn how to construct phrases like "tea with lemon" (чай с лимо́ном) and talk about doing things "with friends" (с друзья́ми).
