Nominative and Accusative Cases in Ukrainian

In Brief

Use the nominative for the subject—the person or thing performing the action—and the accusative for a direct object—the person or thing directly affected by it. In the singular, feminine nouns in -а/-я usually change to -у/-ю; masculine animate nouns follow the genitive pattern, while masculine inanimate and neuter nouns usually look like the nominative.

Overview

Ukrainian nouns have case, meaning that their form can change according to their role in a sentence. The dictionary form is normally the nominative case (називний відмінок). It commonly names the subject: Жінка читає (“The woman is reading”). The subject is simply who or what performs the action.

The accusative case (знахідний відмінок) most often marks the direct object: the person or thing directly seen, bought, read, loved, or otherwise affected by an action. Compare жінка in Жінка читає with жінку in Я бачу жінку (“I see the woman”). English usually shows this distinction through word order; Ukrainian often shows it through endings.

This is an A1 foundation, but the forms depend on gender, noun ending, number, and animacy—whether a noun is grammatically treated as a living being. Start with the singular patterns. The later sections explain adjective agreement, plurals, pronouns, and other uses that you will meet as your Ukrainian develops.

How It Works

Finding the subject and direct object

Ask two practical questions:

1. Who or what performs the action? Put that noun in the nominative.
2. Who or what does the action directly affect? With a verb that takes a direct object, put that noun in the accusative.

In Студент читає книжку (“The student is reading a book”), студент performs the reading, so it is nominative. Книжку is what he reads, so it is accusative.

Ukrainian does not have English articles such as “a” and “the.” Therefore Я купую книжку can mean “I am buying a book” or “I am buying the book”; context supplies the distinction.

Core singular patterns

Nominative form	Accusative form	Pattern	Example meaning
жінка	жінку	feminine -а → -у	woman
земля	землю	feminine -я → -ю	land
ніч	ніч	many feminine nouns in a consonant or -ь stay unchanged	night
студент	студента	masculine animate: accusative = genitive	student
учитель	учителя	masculine animate in -ь: accusative = genitive	teacher
дім	дім	masculine inanimate: accusative = nominative	house
музей	музей	masculine inanimate in -й stays unchanged	museum
місто	місто	neuter: accusative = nominative	city
море	море	neuter: accusative = nominative	sea

The two feminine changes are the most visible beginner pattern:

• -а → -у: кава → каву, книжка → книжку, сестра → сестру
• -я → -ю: пісня → пісню, земля → землю, Марія → Марію

Spelling inside the word can also change according to regular Ukrainian spelling patterns: рука → руку, книга → книгу. Do not treat every final consonant alternation as a separate case rule; learn frequent nouns as a nominative–accusative pair.

Masculine nouns: animacy matters

For a masculine singular noun, ask whether it denotes a person or animal.

• Animate: use a form matching the genitive: Я бачу брата (“I see my brother”), Вона знає лікаря (“She knows the doctor”).
• Inanimate: keep the nominative form: Я бачу будинок (“I see the building”), Ми купуємо телефон (“We are buying a phone”).

“Accusative = genitive” describes the form; it does not mean that the noun is functioning as a genitive. Брата is accusative in Я бачу брата because it is the direct object.

Animacy is less obvious in feminine singular nouns because the ordinary -а/-я → -у/-ю pattern applies to both living and nonliving referents: бачу жінку, бачу собаку, and бачу кімнату. It becomes especially important with masculine nouns and with plurals.

Neuter nouns

Most neuter singular nouns keep the nominative form in the accusative:

• Це вікно. — “This is a window.”
• Я відкриваю вікно. — “I am opening the window.”

The noun’s role changes even though its visible form does not. The verb and sentence meaning tell you that вікно is the direct object in the second sentence.

Adjectives and possessives agree too

An adjective must match its noun in gender, number, and case. A possessive is a word such as “my” or “your” that shows belonging.

Nominative phrase	Accusative phrase	Meaning
нова книжка	нову книжку	a/the new book
синя сукня	синю сукню	a/the blue dress
мій брат	мого брата	my brother (animate)
новий телефон	новий телефон	a/the new phone (inanimate)
велике місто	велике місто	a/the big city

This creates a useful signal: in Я бачу нову книжку, both нову and книжку show the accusative. Masculine animate adjectives generally take the genitive-looking ending -ого/-ього: доброго друга, синього папугу.

Word order does not replace case

Neutral Ukrainian word order often resembles English: subject–verb–object.

Олена читає книжку. — “Olena is reading a book.”

Because the endings identify roles, Ukrainian can rearrange elements for emphasis or context: Книжку читає Олена still means that Olena reads the book, not that the book reads Olena. Beginners should use neutral word order, but they must still choose the correct cases.

Examples in Context

Ukrainian	English	Note
Жінка читає.	The woman is reading.	Жінка is the nominative subject.
Бачу жінку.	I see the woman.	Feminine -а → -у; “I” is understood.
Студентка пише лист.	The student is writing a letter.	Студентка is nominative; inanimate лист is unchanged.
Ми купуємо каву.	We are buying coffee.	Feminine кава → каву.
Вона слухає пісню.	She is listening to a song.	Feminine пісня → пісню.
Я бачу дім.	I see the house.	Masculine inanimate: accusative = nominative.
Дитина відкриває вікно.	The child is opening the window.	Neuter вікно stays unchanged.
Я знаю цього студента.	I know this student.	Masculine animate; both words have accusative forms matching the genitive.
Олена любить свого брата.	Olena loves her brother.	Masculine animate phrase.
Ми бачимо собаку в парку.	We see a dog in the park.	Feminine собака → собаку.
Анна читає нову книжку.	Anna is reading a new book.	Adjective and noun both change.
Учитель пояснює правило.	The teacher explains the rule.	Учитель is nominative; neuter правило is unchanged.
Я чекаю на автобус.	I am waiting for the bus.	на + accusative in this common construction.
Діти йдуть у школу.	The children are going to school.	у + accusative expresses movement toward a destination.

Common Mistakes

Leaving a feminine noun in the nominative

• Wrong: Я читаю книжка.
• Right: Я читаю книжку.
• Why: The book is the direct object. Feminine -а changes to accusative -у.

Changing every masculine direct object

• Wrong: Я купую телефона.
• Right: Я купую телефон.
• Why: Телефон is inanimate, so its singular accusative matches the nominative. The ending -а is used in the accusative pattern for masculine animate nouns, not all masculine nouns.

Not changing a masculine animate noun

• Wrong: Я бачу брат.
• Right: Я бачу брата.
• Why: Брат is masculine and animate, so its accusative matches the genitive form брата.

Changing the noun but not its adjective

• Wrong: Вона купує нова сукню.
• Right: Вона купує нову сукню.
• Why: The adjective must agree with the accusative feminine noun: нова сукня → нову сукню.

Assuming the first noun must be the subject

• Wrong interpretation: Книжку читає Марія = “The book reads Maria.”
• Right interpretation: “Maria is reading the book.”
• Why: Книжку is visibly accusative, while Марія is nominative. Case endings are more reliable than position.

Usage Notes

The subject pronoun is often omitted when the verb form makes the person clear. Бачу жінку naturally means “I see the woman”: the ending of бачу identifies the speaker. The missing pronoun does not change the case of жінку.

The accusative also appears after certain prepositions. Two very frequent patterns are у/в + accusative and на + accusative when movement is directed toward a destination: йти в магазин (“go to the store”), їхати на роботу (“go to work”). By contrast, location at a place normally uses the locative case: у магазині (“in the store”), на роботі (“at work”). Learn these as separate movement-versus-location patterns.

Verb choice matters. English translations do not always reveal which Ukrainian case follows a verb or preposition. For example, the common pattern чекати на когось/щось uses на plus the accusative. Record a new verb together with its usual construction rather than translating one word at a time.

Beyond the Basics / Advanced Use

You do not need to master all of the following at A1, but these patterns explain forms you will soon encounter.

Accusative plurals

In the plural, gender no longer controls the main contrast; animacy does:

Nominative plural	Accusative plural	Pattern
нові будинки	нові будинки	inanimate: accusative = nominative plural
цікаві книжки	цікаві книжки	inanimate: accusative = nominative plural
нові студенти	нових студентів	animate: accusative = genitive plural
маленькі собаки	маленьких собак	animate: accusative = genitive plural

Thus Я бачу нові будинки means “I see new buildings,” but Я бачу нових студентів means “I see new students.” Adjectives follow the same contrast.

Personal pronouns have their own forms

Pronouns do not follow the simple noun-ending chart. Common accusative forms include мене (“me”), тебе (“you,” singular informal), його (“him/it”), її (“her/it”), нас (“us”), вас (“you”), and їх (“them”): Вона знає мене (“She knows me”). These forms overlap with genitive forms, so identify their role from the verb and context.

Time and extent

The accusative can express duration or extent without being a typical affected object: Я працював цілий день (“I worked all day”) and Ми чекали годину (“We waited for an hour”). At first, learn these as common time expressions.

Negation and the genitive

After negation, Ukrainian often uses the genitive where an affirmative sentence has an accusative, especially with absence, nonexistence, indefinite objects, and verbs such as мати: Я маю час → Я не маю часу (“I have time → I do not have time”). Accusative can remain possible in many negative clauses, particularly with a definite or contrastively specific object. This is a nuanced area: the beginner-safe approach is to learn frequent negative expressions as complete patterns, then study Negation separately.

Animacy is grammatical

Animacy broadly follows real-world life, but grammar categories do not always map perfectly onto biology. Some collective, fictional, game-related, or personified nouns can behave according to established usage. When unsure, check a dictionary example rather than guessing from meaning alone.

Practice Tips

1. Build three-column noun cards. Write the nominative, the accusative, and a short sentence: книжка — книжку — Я читаю книжку. Group cards as feminine, masculine animate, masculine inanimate, and neuter.
2. Mark sentence roles before changing endings. Underline the performer once and the directly affected noun twice. Then choose nominative and accusative forms. This prevents English word order from doing all the work.
3. Practise contrasts aloud. Use pairs such as Це студент — Я бачу студента, Це дім — Я бачу дім, and Це нова книжка — Я читаю нову книжку. The contrast makes both unchanged and changed forms memorable.
