Prepositions and Case Government: Overview

If you learn one structural fact about Ukrainian prepositions, learn this: a preposition is never just a word — it is a word plus a case requirement. In English, "without" simply sits in front of "money" and nothing changes. In Ukrainian, без demands the genitive, so "without money" is без гро́шей, with гро́ші reshaped into the genitive. You cannot say the preposition and then reach for a dictionary form; choosing the preposition means choosing the case in the same breath. This page is the conceptual orientation — what "government" is, which cases can be governed, why some prepositions take two cases, and how the spelling shifts for sound. The detailed which-preposition-takes-which-case map lives on the case-after-prepositions page; here we build the mental model.

What "government" means

Government (керува́ння) is the technical term for one word forcing a grammatical form on another. A Ukrainian preposition governs its noun: it dictates the case, and the noun has no choice. The meaning of the phrase is carried jointly by the preposition and the ending — neither alone is enough.

In без парасо́льки, the без signals "absence" and the genitive ending -и confirms it; in для те́бе, для signals "benefit" and the genitive те́бе confirms it. You read the relationship off the pair, working together. This is why you should always memorise a preposition together with the case it takes — без + genitive, для + genitive, про + accusative — as a single unit, never as a bare word.

Five cases can be governed — two cannot

Ukrainian has seven cases, but only five can ever follow a preposition: genitive, dative, accusative, instrumental, and locative. The other two are structurally excluded:

• The nominative is the case of the subject — it never follows a preposition.
• The vocative is the case of direct address (Оле́но! "Olena!") — it stands outside the clause and takes no preposition.

This is a useful filter. If you have parsed a phrase as "preposition + nominative," you have made an error: there is no such combination in Ukrainian. And one case, the locative, goes further — it appears only after a preposition, never on its own. You will never meet a bare locative.

The map in one glance

Here is the whole system compressed — which prepositions cluster under each case. Treat this as a preview; each row has its own detailed page.

The single most important thing to spot in that table: в/на/за/під appear in more than one row. Those are the prepositions that govern two cases — and that is the heart of the system.

One preposition, two cases — meaning chooses

Several prepositions take different cases for different meanings, and the case is what tells the meanings apart. The flagship pair is motion versus location: when a preposition points to a destination (куди? "to where?"), it takes the accusative; when it marks a static place (де? "where?"), it takes the locative or instrumental.

So на стіл (accusative) means "onto the table — put it there," while на столі́ (locative) means "on the table — resting there." The preposition is identical; the ending carries the difference. You always read the meaning off the case, not off the preposition. This alternation is important enough to have its own motion-vs-location page.

A second, lexical kind of two-case preposition is з, which means completely different things depending on case: з + genitive = "from / out of" (з мі́ста "from the city"), but з + instrumental = "with / accompanied by" (з дру́гом "with a friend"). Same preposition, two unrelated meanings, told apart by the ending alone.

Euphonic variants: same preposition, different spelling

A handful of prepositions have two or three spellings that mean exactly the same thing — the choice is purely about sound, to avoid clusters of consonants or vowels that are hard to pronounce. These are the euphonic variants, and they are a hallmark of well-spoken Ukrainian.

These never change the case or the meaning — з, із, зі all govern the same case in a given sense; you simply pick the form that flows. The full rules are on the euphonic variants page. For now, just register that у/в, з/із/зі, від/од are the same preposition, chosen by sound.

Source-language comparison

For an English speaker, the leap is conceptual: a preposition is not a standalone word but a word-plus-case unit that you learn together. Three patterns have no English parallel and cause most early errors: (1) the same preposition takes different cases for different meanings (з = «from» + genitive vs «with» + instrumental); (2) motion vs location flips the case under one preposition (в шко́лу vs в шко́лі); and (3) one English preposition often splits across several Ukrainian ones — English «to» maps to до (+ genitive, «to a place»), в/на (+ accusative, «into»), or a bare dative (to a person) depending on sense. There is no shortcut: you build a mental table of preposition + case + meaning.

For a Russian speaker, the framework is parallel and transfers well, but watch the Ukrainian specifics surfaced here: "about a topic" is про + accusative (not о + prepositional), "thanks to" is завдяки́ + dative, and the euphonic set у/в, з/із/зі, від/од plus the lexical в-vs-на choices (у шко́лі, на робо́ті) follow Ukrainian, not Russian, distribution.

Common Mistakes

Key Takeaways

• A Ukrainian preposition governs a case — learn the preposition and its case as one unit (без + genitive, про + accusative).
• Only five cases are governable: genitive, dative, accusative, instrumental, locative. The nominative and vocative never follow a preposition; the locative appears only after one.
• Some prepositions take two cases for two meanings: motion (accusative) vs location (locative/instrumental) under на/в/за/під; and з = "from" (gen.) vs "with" (instr.). Read the ending, not the preposition.
• Euphonic variants (з/із/зі, у/в, від/од) are the same preposition spelled for sound — they change neither case nor meaning.
• The detailed which-case-after-which-preposition map is on the case-after-prepositions page.
