Wrong Case After Prepositions | Ukrainian Grammar

In Ukrainian a preposition does not just sit in front of a noun — it demands a specific case, and often the same preposition demands different cases depending on meaning. Get the case wrong and the sentence is ungrammatical, sometimes comically so: в шко́лу means "to school" but в шко́лі means "at school," and the only difference is the case ending. This page gathers the errors learners make most often after prepositions, sorted into the two families that cause almost all of them: choosing the wrong case for motion versus location, and importing Russian preposition-plus-case patterns that Ukrainian does not use.

💡

Two questions fix the vast majority of preposition errors. First: am I moving toward a place (accusative) or already at it (locative)? Second: is this preposition-plus-case combination actually Ukrainian, or did I copy it from Russian or English? Ask both before you commit to an ending.

Family 1: motion vs location

The prepositions в/у and на govern two cases. With a verb of motion (going to, putting onto), they take the accusative. With a verb of position or location (being at, lying on), they take the locative. This is the single most productive error in beginner Ukrainian, and it is fully explained on the motion-vs-location page.

The error is using the accusative (the "to" form) when you mean a static location.

❌ Я зара́з у шко́лу, передзвоню́ пі́зніше.

Incorrect — 'I'm at school' is a location, so в takes the locative: у шко́лі. The accusative у шко́лу means motion 'to school'.

✅ Я зара́з у шко́лі, передзвоню́ пі́зніше.

I'm at school right now, I'll call back later.

And the mirror error — using the locative when you mean motion toward a place:

❌ Ді́ти побі́гли на ву́лиці гра́тися.

Incorrect — 'ran out onto the street' is motion, so на takes the accusative: на ву́лицю. The locative на ву́лиці means the static 'on the street'.

✅ Ді́ти побі́гли на ву́лицю гра́тися.

The kids ran out onto the street to play.

The same split applies to на with surfaces and events:

❌ Покладі́ть, будь ла́ска, докуме́нти на столі́.

Incorrect — 'put onto the table' is motion, so на takes the accusative: на стіл. The locative на столі́ means 'lying on the table'.

✅ Покладі́ть, будь ла́ска, докуме́нти на стіл.

Please put the documents on the table.

Family 2: до + genitive, not accusative

The preposition до ("to, up to, until") governs the genitive, full stop. Learners — especially English speakers thinking "to → accusative" — frequently put the accusative after it. Even for motion toward a place, до takes the genitive: іду́ до шко́ли, не *до шко́лу.

❌ Уве́чері я йду до ба́бусю.

Incorrect — до always governs the genitive: до ба́бусі. The accusative ба́бусю is wrong here.

✅ Уве́чері я йду до ба́бусі.

This evening I'm going to grandma's.

Family 3: Russian preposition-plus-case patterns

Several Ukrainian constructions use a different preposition or case from their Russian counterparts. A Russian-trained ear copies the Russian frame and produces a sentence that is grammatical-looking but unidiomatic.

одружитися З + instrumental, not "на" + locative

Russian marries "на ком" (one marries onto a person). Ukrainian marries з ким — одружи́тися з + instrumental — you marry with someone, like a partnership.

❌ Він одружи́вся на Окса́ні мину́лого ро́ку.

Incorrect — the одружи́тися на pattern is Russian. Standard Ukrainian is одружи́тися з + instrumental: з Окса́ною.

✅ Він одружи́вся з Окса́ною мину́лого ро́ку.

He married Oksana last year.

сміятися З + genitive, not "над" + instrumental

Russian laughs "над кем" (over a person). Ukrainian laughs з кого — сміятися з + genitive.

❌ Не смі́йся над ним, він і так засмучений.

Incorrect — сміятися над is Russian; standard Ukrainian is сміятися з + genitive: з ньо́го.

✅ Не смі́йся з ньо́го, він і так засмучений.

Don't laugh at him, he's upset as it is.

грати В + accusative for games

To play a game, Ukrainian inserts в/у + accusative — гра́ти в футбо́л, гра́ти в ша́хи. Dropping the preposition (a calque of English "play football" or a partial Russian transfer) is wrong. Note that for musical instruments it is гра́ти на + locative (гра́ти на гіта́рі).

❌ Хло́пці після уро́ків гра́ють футбо́л.

Incorrect — games take в/у + accusative: гра́ти в футбо́л. The bare object is wrong.

✅ Хло́пці після уро́ків гра́ють у футбо́л.

After lessons the boys play football.

про + accusative for "about," not о/об + locative

Russian talks "о чём" (об + prepositional). Ukrainian talks про що — про + accusative. The о/об + locative pattern is a russism in this meaning.

❌ Ми до́вго говори́ли о пого́ді.

Incorrect — 'about' is про + accusative in Ukrainian: про пого́ду. The о + locative pattern is Russian.

✅ Ми до́вго говори́ли про пого́ду.

We talked about the weather for a long time.

"By car": bare instrumental, no preposition

To express the means of transport, Ukrainian uses the bare instrumental — маши́ною, по́тягом, авто́бусом — with no preposition. Inserting з (a calque of English "by" / "with") is wrong, because з + instrumental means literal accompaniment ("together with"). See the three meanings of з.

❌ Ми пої́хали до Льво́ва з маши́ною.

Incorrect — means of transport is the bare instrumental: маши́ною. With з it would mean 'together with the car', which is nonsense here.

✅ Ми пої́хали до Льво́ва маши́ною.

We went to Lviv by car.

💡

Mind the two senses of з + instrumental: accompaniment (з дру́гом 'with a friend') is real, but means/instrument never takes з — you write з ру́чкою only if you mean "together with a pen," not "using a pen." Means is bare instrumental: пишу́ ру́чкою 'I write with a pen', їду по́тягом 'I travel by train'.

"From": з/із + genitive vs від + genitive

Both з and від translate English "from," but they are not interchangeable. З/із + genitive means "out of" a place (з ки́шені "out of the pocket," з Льво́ва "from Lviv, out of the city"). Від + genitive means "away from" a person or starting point (лист від ма́ми "a letter from mum," відійти́ від вікна́ "step away from the window"). Using з for a person is a common slip.

❌ Я отри́мав лист з ба́тька.

Incorrect — 'from a person' is від + genitive: від ба́тька. З + genitive means 'out of' a place.

✅ Я отри́мав лист від ба́тька.

I received a letter from my father.

Source-language comparison

For an English speaker, the trap is that English uses one preposition for many cases ("to school," "to grandma's," "to me") and never marks the noun, so you are blind to the case the Ukrainian preposition wants. Worse, "to" pulls you toward the accusative everywhere, but Ukrainian splits the work: в/на + accusative for motion, but до + genitive, and в/на + locative for location.

For a Russian speaker, the prepositions look identical but the frames differ in exactly the high-frequency verbs — marry, laugh, talk about. The Russian одружи́тися-на / сміятися-над / говори́ти-о patterns are precisely the ones that survive into суржик, so they deserve targeted drilling: з, з, про.

Common Mistakes

❌ Ма́ма на ку́хню, гото́вить вече́рю.

Incorrect — 'in the kitchen' is a location, so на takes the locative: на ку́хні. The accusative на ку́хню means motion 'into the kitchen'.

✅ Ма́ма на ку́хні, гото́вить вече́рю.

Mum is in the kitchen, making dinner.

❌ Завтра ми йдемо́ до теа́тр.

Incorrect — до always governs the genitive: до теа́тру.

✅ Завтра ми йдемо́ до теа́тру.

Tomorrow we're going to the theatre.

❌ Вона́ хо́че одружи́тися на цьо́му хло́пцеві.

Incorrect — одружи́тися на is Russian; standard Ukrainian is одружи́тися з + instrumental: з цим хло́пцем.

✅ Вона́ хо́че одружи́тися з цим хло́пцем.

She wants to marry this boy.

❌ Усі почали́ сміятися над мої́м акце́нтом.

Incorrect — сміятися над is Russian; standard Ukrainian is сміятися з + genitive: з мого́ акце́нту.

✅ Усі почали́ сміятися з мого́ акце́нту.

Everyone started laughing at my accent.

❌ Розкажи́ мені́ о свої́й пої́здці.

Incorrect — 'about' is про + accusative: про свою́ пої́здку. The о + locative pattern is Russian.

✅ Розкажи́ мені́ про свою́ пої́здку.

Tell me about your trip.

Key Takeaways

в/у and на take the accusative for motion (в шко́лу, на стіл) and the locative for location (в шко́лі, на столі́) — pick by asking "moving toward, or already there?"
до always governs the genitive, even for motion: до шко́ли, до теа́тру.

      - acc.
Means of transport is the bare instrumental (маши́ною, по́тягом) — never з.
"From": з/із = out of a place, від = away from a person/point.
