Instrumental Case in Ukrainian

In Brief

The Ukrainian instrumental case (орудний відмінок) changes a noun to show a tool or means, a companion, a role, or a relationship expressed by certain prepositions. Compare ручка “pen” with Пишу ручкою “I write with a pen,” and брат “brother” with Іду з братом “I’m going with my brother.” The most useful endings to learn first are masculine and neuter -ом/-ем, feminine -ою/-ею, and plural -ами/-ями.

Overview

A case is a change in the form of a noun, pronoun, or adjective that shows what that word is doing in a sentence. English usually relies on word order and words such as “with,” “by,” or “as.” Ukrainian often changes the ending too: лікар “doctor” becomes лікарем, and школа “school” becomes школою.

At A2, the instrumental gives you several useful everyday patterns. It names the object used to perform an action, as in відчинити ключем “open with a key”; it follows з/із/зі when people or things are together, as in чай з лимоном “tea with lemon”; and it describes professions, roles, and states, especially after бути “to be,” стати “to become,” and працювати “to work.” It also follows prepositions such as між “between,” над “above,” під “under,” перед “in front of,” and spatial за.

For an English-speaking learner, “with” is not a reliable signal by itself. Ukrainian normally uses the instrumental without a preposition for a tool—писати олівцем—but uses з + instrumental for company—писати з другом. The question words associated with the case are ким? “by/with whom?” and чим? “by/with what?”

How It Works

The beginner rule

Start by identifying the meaning, then change every agreeing word in the noun phrase:

1. Tool, means, or transport: instrumental alone.
2. Company or an added ingredient: з/із/зі + instrumental.
3. Profession, role, or resulting state: instrumental after verbs such as бути, стати, and працювати.
4. Position in relation to something: instrumental after між, над, під, перед, and spatial за.

A noun is a word for a person, place, thing, or idea. Its ending depends on gender and stem type, so the table gives common patterns rather than one universal ending.

Singular noun endings

Noun type	Nominative (dictionary form)	Instrumental	Main pattern
Masculine, hard stem	брат, стіл	братом, столом	add -ом
Masculine, soft or й-type stem	учитель, герой	учителем, героєм	usually -ем/-єм
Neuter in -о	місто	містом	replace -о with -ом
Neuter in -е	море	морем	replace -е with -ем
Neuter in -я	життя	життям	usually -ям
Feminine in -а	школа	школою	replace -а with -ою
Feminine in -я	земля, надія	землею, надією	usually -ею/-єю
Feminine ending in a consonant	ніч, любов	ніччю, любов’ю	usually -ю, often with a stem change or doubled consonant

Spelling and stem changes matter. For example, рука → рукою, друг → другом, but ніч → ніччю and сіль → сіллю. It is more effective to learn frequent nouns as pairs than to try to predict every form from the broad table.

Some neuter nouns have expanded stems: ім’я → ім’ям, теля → телям. These belong to less regular declension patterns and can be learned individually at first.

Plural endings

Most plural nouns use -ами or -ями:

Nominative plural	Instrumental plural	English
брати	братами	brothers / with brothers
книги	книгами	books / with books
учителі	учителями	teachers / with teachers
пісні	піснями	songs / with songs
моря	морями	seas / by the seas

A few very common plurals are irregular, including люди → людьми “people,” діти → дітьми “children,” гроші → грошима “money,” and очі → очима “eyes.”

Adjectives and other agreeing words

An adjective is a describing word such as “new,” “blue,” or “Ukrainian.” It must match the noun in gender, number, and case.

Form	Masculine	Feminine	Neuter	Plural
Nominative	новий лікар	нова ручка	нове авто	нові друзі
Instrumental	новим лікарем	новою ручкою	новим авто	новими друзями

The common instrumental adjective endings are -им for masculine and neuter, -ою for feminine, and -ими for plural. Soft-pattern adjectives use forms such as синім, синьою, синіми.

Personal pronouns

A pronoun is a short word used instead of a noun, such as “I,” “you,” or “they.” Instrumental pronouns are highly frequent and should be memorized.

Basic pronoun	Instrumental	With з/із/зі	English
я	мною	зі мною	with me
ти	тобою	з тобою	with you (singular, informal)
він	ним	з ним	with him
вона	нею	з нею	with her
воно	ним	з ним	with it
ми	нами	з нами	with us
ви	вами	з вами	with you (plural or polite)
вони	ними	з ними	with them

After a preposition, third-person pronouns begin with н-: ним, нею, ними. Forms such as з ім or з єю are not standard.

Tools and means: no з

When a noun tells you what you physically use to do something, Ukrainian normally puts it directly in the instrumental:

• різати ножем — to cut with a knife
• малювати олівцем — to draw with a pencil
• платити карткою — to pay by card
• надіслати поштою — to send by mail

Transport often follows the same pattern: їхати автобусом, летіти літаком, подорожувати потягом. In everyday speech, їхати на автобусі is also heard, but the instrumental pattern is a clear, standard way to name the means of transport.

Company and combination: з/із/зі

Use з + instrumental when people or things accompany each other or are combined:

• з сестрою — with (my/the) sister
• кава з молоком — coffee with milk
• бутерброд із сиром — a sandwich with cheese
• зі мною — with me

The variants з, із, зі have the same basic meaning here. The choice mainly makes pronunciation smoother: зі мною, із сестрою, з другом. There can be stylistic variation, so listen for whole phrases rather than treating the variants as different grammar.

Do not confuse this with з/із + genitive, which can mean “from” or “out of”: з братом “with my brother,” but з Києва “from Kyiv.” The noun ending reveals the meaning.

Roles, professions, and changes of state

The instrumental commonly names what someone is, was, becomes, remains, or works as:

• Вона була студенткою. — She was a student.
• Він стане лікарем. — He will become a doctor.
• Я працюю перекладачем. — I work as a translator.
• Вони залишилися друзями. — They remained friends.

In the present tense, Ukrainian often omits бути entirely. A simple, current identity is commonly nominative: Він лікар “He is a doctor.” The explicit sentence Він є лікарем is grammatical, but є may sound emphatic, contrastive, or more formal than the ordinary zero-copula sentence. In the past and future, the instrumental is especially natural: Він був лікарем; Він буде лікарем.

Prepositions of position

The following prepositions regularly take the instrumental when they describe a location or static relationship:

Preposition	Example	Meaning
між	між домом і школою	between the house and the school
над	над столом	above the table
під	під ліжком	under the bed
перед	перед будинком	in front of the building
за	за дверима	behind the door
за	за столом	at the table / seated at the table

With між, each coordinated noun takes the instrumental: між старим будинком і новою школою.

Common Mistakes

Adding з before a tool

• Wrong: Пишу з ручкою. (if you mean that the pen is the writing tool)
• Right: Пишу ручкою.
• Why: A tool normally uses the instrumental without a preposition. З ручкою means “with a pen” in the sense of having or carrying one, not necessarily using it to write.

Omitting з for a companion

• Wrong: Іду братом.
• Right: Іду з братом.
• Why: A companion requires з/із/зі + instrumental. The bare instrumental does not normally express “together with a person.”

Using the dictionary form after a preposition

• Wrong: між дім і школа
• Right: між домом і школою
• Why: між governs the instrumental, and both nouns joined by і must take that case.

Changing the noun but not the adjective

• Wrong: з новий учителем
• Right: з новим учителем
• Why: Every agreeing word changes. Here both новим and учителем are masculine singular instrumental.

Treating every present identity as instrumental

• Awkward as a neutral introduction: Я є студентом.
• Natural: Я студент.
• Also natural in the past: Я був студентом / Я була студенткою.
• Why: Present-tense бути is usually omitted, and the nominative commonly expresses simple identity. Instrumental is central after past/future бути, after стати, and when a role rather than a simple label is foregrounded.

Confusing “with” and “from” after з

• Wrong: interpreting з другом as “from a friend”
• Right: з другом = “with a friend”; від друга = “from a friend” in many source/recipient contexts
• Why: з + instrumental expresses company, while source з + genitive appears in phrases such as з міста “from the city.” English “from” does not always map to one Ukrainian preposition.

Usage Notes

Ukrainian does not have articles equivalent to English “a” and “the.” Therefore з братом can mean “with a brother,” “with the brother,” or “with my brother,” depending on context. Do not add a possessive unless Ukrainian needs to make ownership explicit.

Profession words may have masculine and feminine forms. A woman may say Я працюю лікаркою and a man Я працюю лікарем. Usage varies by profession and speaker, but productive feminine job titles are normal in contemporary Ukrainian. The case ending is added to the chosen noun: директорка → директоркою, авторка → авторкою.

The prepositions під and за can take different cases with different meanings. Instrumental usually presents a location: Кіт під столом “The cat is under the table.” Accusative can mark movement toward a position: Кіт заліз під стіл “The cat crawled under the table.” At A2, remember the safe contrast “location = instrumental”; learn the motion patterns as whole verb-preposition phrases.

Beyond the Basics / Advanced Use

You do not need to produce all of these patterns at A2, but you will encounter them in speech and writing.

The instrumental can describe manner or a characteristic way of acting: говорити спокійним голосом “speak in a calm voice,” дивитися уважним поглядом “look with an attentive gaze.” It also appears in route expressions such as іти лісом “go through/by way of the forest” and recurring time expressions such as вечорами “in the evenings.” These uses are best learned as recurring patterns, not as literal translations of English “with.”

In passive constructions, the person or force carrying out an action may appear in the instrumental: Роман написаний українською авторкою “The novel was written by a Ukrainian woman author.” This is called the agent—the person or thing that performs the action even though the sentence focuses on the result. Ukrainian often avoids heavy passive phrasing and uses an active sentence instead, so do not automatically copy every English “by” phrase.

Predicative case choice—the case used for a label or description after “be”—has semantic and stylistic nuance. The nominative often presents identity as a direct fact: Олег — учитель. The instrumental is strongly associated with a role, profession, temporary capacity, or a state across time: Олег був учителем, Олег став учителем. Context matters more than a rule that “to be always takes instrumental.”

Finally, fixed government extends beyond the core verbs listed here. Some verbs and expressions select the instrumental, for example керувати компанією “manage a company,” цікавитися історією “be interested in history,” пишатися сином “be proud of one’s son,” and користуватися словником “use a dictionary.” In such cases, memorize the verb together with its question and a model noun: цікавитися чим? — музикою.

Practice Tips

1. Build four-word families. Take one noun and make a useful set: ручка — ручкою — новою ручкою — писати новою ручкою. This trains both the noun and adjective ending in a real phrase.
2. Sort “with” by meaning. When translating an English sentence, ask whether “with” introduces a tool or a companion. Write two columns: ножем, ключем, карткою without з; з другом, з мамою, зі мною with з/із/зі.
3. Practice location and movement in pairs. Say Книжка під столом and Поклади книжку під стіл. Even before mastering the accusative contrast, hearing the pair helps prevent the static instrumental pattern from being overextended.
