Russian Prepositional Case: Endings, в vs на, о чём & 30 Examples | Russian Cases with Anna

The Russian prepositional case has a distinction no other case can claim: it is the only Russian case that is never used without a preposition. Every other case can appear in a sentence on its own — a noun in the nominative is simply the subject, a noun in the instrumental can be a tool. But a noun in the prepositional? It always comes attached to в, на, о, при, or по.

This makes it paradoxically one of the easiest to master: if you see one of those five prepositions, you know the prepositional case follows. And the endings themselves are among the most consistent in Russian grammar.

Quick Answer

The prepositional case answers О ком? (About whom?) and О чём? (About what?) — and also Где? (Where?) when expressing location.

It is used for location (в школе — at school), topic (о работе — about work), and conditions (при Сталине — under Stalin).

What Is the Russian Prepositional Case?

The prepositional case (Предложный падеж — literally 'the proposed/prepositional case') is the sixth and last of the Russian cases. Unlike the other five cases which can sometimes function without a preposition, the prepositional is always preceded by one of five prepositions: в, на, о/об, при, or по (in certain constructions).

Core examples: Я живу в Москве. — I live in Moscow. | Мы говорим о работе. — We talk about work.

The prepositional case is used with:

В + location (in/inside a place): Я в школе. — I am at school.
НА + location (on/at a place): Книга на столе. — The book is on the table.
О/ОБ + topic (about): Мы говорим о погоде. — We talk about the weather.
ПРИ + conditions/presence (under/in the presence of): при Сталине, при свидетелях
ПО + certain fixed expressions (upon, after): по приезде (upon arrival)

Key rule

The prepositional NEVER appears without one of these prepositions — guaranteed!

Russian Prepositional Case Endings — Complete Table

The prepositional case has some of the most regular endings in Russian. Most nouns simply take -Е in the singular.

The key exceptions are nouns ending in -ий, -ие, -ия (which take -ИИ) and a small group with irregular locative -У forms.

Prepositional case endings by noun type

| Noun type | Ending | Formation | Result | Example in context | | --- | --- | --- | --- | --- | | Masc. hard (consonant) | -е | стол → стол+е | столе | книга на столе — book on the table | | Masc. soft (-й) | -е | музей → музе+е | музее | в музее — in the museum | | Masc. soft (-ь) | -е | словарь → словар+е | словаре | в словаре — in the dictionary | | Masc./Neut. in -ий/-ие | -ии | гений → гени+и / здание → здани+и | гении / здании | в здании — in the building | | Fem. hard (-а) | -е | страна → стран+е | стране | в стране — in the country | | Fem. soft (-я) | -е | земля → земл+е | земле | на земле — on the ground | | Fem. in -ия | -ии | станция → станци+и | станции | на станции — at the station | | Fem. (-ь) | -и | ночь → ноч+и | ночи | в ночи — in the night | | Neuter (-о) | -е | окно → окн+е | окне | в окне — in the window | | Neuter (-е) | -е | море → мор+е | море | в море — in the sea | | Neuter in -ие | -ии | здание → здани+и | здании | в здании — in the building | | Plural (all genders) | -ах/-ях | столы→столах / моря→морях | столах / морях | в домах — in the houses |

The golden rule: almost everything takes -Е in the prepositional singular.
Masculine -ий — -ИИ: гений → о гении
Neuter -ие — -ИИ: здание → в здании, упражнение → в упражнении
Feminine -ия — -ИИ: станция → на станции, Россия → в России
Feminine -ь — -И: ночь → о ночи
Plural (hard stem) — -АХ: в домах
Plural (soft stem) — -ЯХ: в морях, о людях

The Special -ИИ Ending: Nouns in -ий, -ие, -ия

The most important exception to the standard -Е ending is the group of nouns ending in -ий (masculine), -ие (neuter), and -ия (feminine). These take -ИИ in the prepositional case instead of the expected -Е.

This is a very common source of errors.

The -ИИ rule — examples you MUST know:

Masculine -ий — гений → о гении (not о гение)
Neuter -ие — здание → в здании, упражнение → в упражнении, путешествие → о путешествии
Feminine -ия — станция → на станции, Россия → в России, революция → о революции, Италия → в Италии

Memory trick

-ий/-ие/-ия all end in И — they keep that И in the prepositional.

The Locative Case Remnant: Irregular -У Endings

A small but very common group of masculine nouns have an irregular prepositional ending: -У (or -Ю for soft stems) instead of the standard -Е. This special form is called the 'locative' (местный падеж) — a remnant of an older Russian case, used exclusively with в and на when expressing location (not topic).

These nouns have TWO prepositional forms: the -У form for location (в/на + place) and the regular -Е form for topic (о + subject).

Locative -У vs regular prepositional -Е

| Noun | Locative (в/на + location) | Regular prep. (о + topic) | Example sentence | | --- | --- | --- | --- | | лес (forest) | в лесу | о лесе | Мы заблудились в лесу. — We got lost in the forest. | | сад (garden) | в саду | о саде | Дети играют в саду. — Children play in the garden. | | год (year) | в году | о годе | Сколько дней в году? — How many days in a year? | | пол (floor) | на полу | о поле | Кот лежит на полу. — The cat lies on the floor. | | берег (shore) | на берегу | о береге | Мы отдыхали на берегу. — We rested on the shore. | | угол (corner) | в углу | об угле | Стол стоит в углу. — The table stands in the corner. | | нос (nose/bow) | на носу | о носе | Очки на носу. — Glasses are on the nose. | | порт (port) | в порту | о порте | Корабль в порту. — The ship is in port. | | мост (bridge) | на мосту | о мосте | Встретимся на мосту. — Let's meet on the bridge. | | снег (snow) | в снегу | о снеге | Дети играли в снегу. — Children played in the snow. |

В/НА + [locative -У] = physical location (where something IS): в лесу, на полу, в порту
О + [regular -Е] = topic, subject of discussion: о лесе, о поле, о порте
These nouns are common and high-frequency — worth memorizing as a set.

В vs. НА — Which to Use for Location?

Two prepositions — в and на — can both mean 'at' or 'in' for location in the prepositional case.

Choosing the right one is one of the trickiest aspects of Russian location grammar.

В vs. НА for location and direction

| Location type | В/НА + prepositional (location) | В/НА + accusative (direction) | Example | | --- | --- | --- | --- | | Country | в России, в Германии, в Китае | в Россию (acc.) | В России холодно зимой. — It is cold in Russia in winter. | | City | в Москве, в Лондоне, в Париже | в Москву (acc.) | Он живёт в Москве. — He lives in Moscow. | | Building | в школе, в банке, в больнице | в школу (acc.) | Дети в школе. — The children are at school. | | Island/peninsula | на Кубе, на Сахалине | на Кубу (acc.) | Они отдыхают на Кубе. — They vacation in Cuba. | | Open space | на улице, на площади | на улицу (acc.) | Дети играют на улице. — Children play outside. | | Event | на концерте, на конференции | на концерт (acc.) | Я был на концерте. — I was at the concert. | | Work/institution | на работе, на заводе, на почте | на работу (acc.) | Она на работе. — She is at work. | | Floor/surface | на полу, на столе, на крыше | на пол (acc.) | Кот сидит на полу. — The cat sits on the floor. |

В (in/inside) is used for enclosed spaces: rooms, buildings, countries, cities.
НА (on/at) is used for surfaces, open spaces, events, and certain institutions by convention.
Tricky НА locations (use на, not в): на работе, на почте, на заводе, на рынке, на вокзале, на стадионе, на Украине, на Кубе, на Сахалине.

О/ОБ: The "About" Preposition in Russian

The preposition о (or об before words starting with a vowel sound) followed by the prepositional case is used to express the topic of conversation, thought, writing, or any form of mental engagement.

О vs. ОБ

Use ОБ when the next word starts with a vowel (а, е, ё, и, о, у, э, ю, я) or with Ъ or Ь. In all other cases, use О.

о работе (about work) — standard О
об этом (about this) — ОБ before э
о ней (about her) — standard О
об Иване (about Ivan) — ОБ before И
об ошибке (about the mistake) — ОБ before О

О чём? — How to Ask "About What?" in Russian

The question form О чём? (About what?) is the prepositional form of что (what).

This is one of the most useful question words in Russian.

О чём вы говорите? — What are you talking about?
О чём эта книга? — What is this book about?
О чём ты думаешь? — What are you thinking about?
О чём ты мечтаешь? — What do you dream about?
О ком вы говорите? — Who are you talking about? (О ком = about whom)
О ком написана эта статья? — Who is this article about?

Prepositional vs. Accusative with В and НА

Summary of the contrast:

В/НА + Accusative = DIRECTION (motion toward): Я иду в школу. | Она едет на работу. | Он положил книгу на стол.
В/НА + Prepositional = LOCATION (being somewhere, static): Я нахожусь в школе. | Она работает на заводе. | Книга лежит на столе.

Frequently Asked Questions

Why is it called the "prepositional" case?

The Russian prepositional case gets its name because it is the only case that always requires a preposition. No other Russian case has this property — the nominative, genitive, dative, accusative, and instrumental can all appear without a preposition. The prepositional, by definition, cannot.

What is the difference between в and на for location in Russian?

В (in) is used for enclosed or interior spaces: countries, cities, buildings, and rooms. НА (on/at) is used for surfaces, open spaces, islands, and a set of specific institutions by convention (на работе, на почте, на вокзале). Both take the prepositional for location and the accusative for direction.

What is о чём in Russian?

О чём is the prepositional form of что (what), used with the preposition о (about). It means "about what" and is used to ask what something is about: О чём эта книга? (What is this book about?), О чём вы думаете? (What are you thinking about?). The related form О ком? (about whom?) uses the prepositional form of кто.

What are locative forms in Russian?

Locative forms are irregular prepositional endings (-У/-Ю instead of -Е) used with a small group of masculine nouns when expressing physical location with в or на. Examples: в лесу (in the forest), на полу (on the floor), в году (in the year), на берегу (on the shore). These same nouns use the standard -Е ending when used with о to express topic: о лесе (about the forest), о поле (about the field).
