In short

To say “I have a car” in everyday Ukrainian, you do not use a verb “to have” the way English does. Instead you say the equivalent of “at me is a car”: у ме́не є маши́на. The possessor goes into the genitive after the preposition у (or в), and the thing possessed stays in the nominative as the grammatical subject, followed by є (“is/exists”). The verb ма́ти (“to have”) does exist and is fully correct, but it sounds more bookish and is used less often in casual speech. Master у + genitive + є first — it is what Ukrainians actually say.

The rule

Ukrainian expresses possession with an existential frame, literally “by/at someone there-is something”:

у / в + [possessor in GENITIVE] + є + [thing in NOMINATIVE]

• у ме́не є — I have (lit. “at me there is”)
• у те́бе є — you have (informal)
• у ньо́го / у не́ї є — he / she has

Key points:

1. The possessor takes the genitive case (see Genitive case). With pronouns you use their special genitive-after-preposition forms (ме́не, те́бе, ньо́го, не́ї, нас, вас, них).
2. The thing possessed is the subject and stays in the nominative.
3. є means “is / there is / exists”. In the present tense it is often dropped when you merely describe what kind of thing you have, but it is kept when you assert that you have something at all (see Tips).
4. у becomes в before a vowel for euphony (в А́нни є…); this is the ordinary у/в alternation from Euphony: у/в, і/й, з/зі/із.
5. Negation uses a different verb: instead of “не є” you say нема́є (“there is no”), and — importantly — the thing possessed then switches to the genitive: у ме́не нема́є маши́ни (“I don’t have a car”).

The bookish alternative is the verb ма́ти + a direct object in the accusative: я ма́ю маши́ну. It conjugates like a normal verb (я ма́ю, ти ма́єш, він ма́є…). Use it in writing, fixed phrases (ма́ти ра́цію “to be right”, ма́ти на ува́зі “to mean/have in mind”), but prefer у + genitive + є in conversation.

Forms & patterns

Genitive pronoun forms used after у / в (the possessor slot):

Nouns as possessor simply go into the genitive: у бра́та є (brother), в А́нни є (Anna), у ба́тька є (father), у студе́нтів є (students).

Present vs. negative (note the case switch on the possessed thing):

Bookish ма́ти (present tense), object in the accusative:

Common mistakes

• Я є маши́на. -> У ме́не є маши́на. — “I have a car” is not “I am a car”; use the у + genitive frame, not a copula.
• У я є час. -> У ме́не є час. — after у/в the pronoun must be genitive (ме́не), never nominative (я).
• У ме́не не є соба́ки. -> У ме́не нема́є соба́ки. — negate possession with нема́є, not “не є”.
• У ме́не нема́є маши́на. -> У ме́не нема́є маши́ни. — after нема́є the thing goes into the genitive (маши́ни), not the nominative.
• Я ма́ю маши́на. -> Я ма́ю маши́ну. — the verb ма́ти takes a direct object in the accusative, not the nominative.
• У ме́не ма́ю час. -> У ме́не є час. or Я ма́ю час. — do not blend the two constructions; pick one.

Tips

• Default to у + genitive + є in speech; save ма́ти for writing and set phrases (ма́ти ра́цію, ма́ти на ува́зі, ма́ти можли́вість “to have the opportunity”).
• Keep є when you assert that something exists (“Do you have a pen?” — У вас є ру́чка?). You can drop it when the focus is which kind: У ме́не га́рна ру́чка (“My pen is nice / I have a nice pen”).
• Remember the negation flip: affirmative є + nominative, but negative нема́є + genitive. This mirrors the genitive of negation you met in Genitive case.
• у before a consonant, в before a vowel: у бра́та, but в Оле́ни, в А́нни. Same rule as Euphony: у/в, і/й, з/зі/із.
• Use ти-forms (у те́бе) with friends and family, ви-forms (у вас) for politeness or plural — the ordinary ти/ви address (informal vs formal) choice.
• To ask “who has…?” say У ко́го є…? — ко́го is the genitive of хто.
• Past and future reuse the frame with бу́ти: у ме́не був час (“I had time”), у ме́не бу́де час (“I will have time”) — you will meet these tenses later.
