The Accusative Case for Direction of Motion

Welcome to our lesson on expressing movement! 🗺️
Today, we'll learn how to say where you are going in Russian. This is a very common and useful topic. In English, you say 'I am going TO the park'. That little word 'to' indicates direction. In Russian, we show this direction using a special grammar case called the Accusative case.

First, let's learn a crucial question: Куда́? (Koo-DA?). This means 'Where to?' or 'To what place?'. It specifically asks about the destination of a movement.
➡️ Куда́ ты идёшь? - Where are you going (to)?

It's very important not to confuse Куда́? with Где? (Gdye?). Где? means 'Where?' and asks about a static location.
📍 Где ты? - Where are you?

So, remember:

• Movement towards a place = Куда́?
• Being in a place = Где?

The answer to the question Куда́? always requires the Accusative case.

Prepositions of Direction: В and НА
To indicate direction, we use two main prepositions before the noun: в (in/into) and на (on/onto).

1️⃣ The Preposition В (in/into)
We use в when talking about going into an enclosed space or a location with clear boundaries, like a building, a city, or a country.
Think of it as 'going inside' something.

Examples of places that use в:

• в банк (to the bank)
• в магази́н (to the store)
• в шко́лу (to school)
• в университе́т (to the university)
• в теа́тр (to the theater)
• в кино́ (to the cinema)
• в го́род (to the city)
• в Росси́ю (to Russia)

2️⃣ The Preposition НА (on/onto)
We use на for open spaces, events, and some specific locations that are exceptions by tradition.
Think of it as 'going onto' a surface or 'to' an event.

Examples of places that use на:

• на рабо́ту (to work)
• на у́лицу (to the street)
• на стадио́н (to the stadium)
• на конце́рт (to a concert)
• на ле́кцию (to a lecture)
• на по́чту (to the post office)
• на вокза́л (to the train station) - Note: this is a building, but it's a common exception!

Memorizing which places use в and which use на is important.

How to Form the Accusative Case for Direction
Now for the main part! When we use в or на to show direction, the noun that follows must be in the Accusative case. Here’s how the endings change for inanimate nouns (places, objects).

📘 Masculine Nouns
Good news! For inanimate masculine nouns (ending in a consonant, -й, -ь), the ending does not change.

• парк (a park) -> Я иду́ в парк.
• музе́й (a museum) -> Мы идём в музе́й.
• стадио́н (a stadium) -> Они́ иду́т на стадио́н.

📗 Neuter Nouns
More good news! Neuter nouns (ending in -о, -е) also do not change in the Accusative case.

• кино́ (cinema) -> Ты идёшь в кино́?
• мо́ре (sea) -> Мы е́дем на мо́ре.
• зда́ние (building) -> Он идёт в зда́ние.

📕 Feminine Nouns
This is where you need to pay attention! Feminine nouns DO change their endings.

• If the noun ends in -а, change it to -у.
• шко́ла (school) -> в шко́лу
• рабо́та (work) -> на рабо́ту
• у́лица (street) -> на у́лицу
• If the noun ends in -я, change it to -ю.
• Росси́я (Russia) -> в Росси́ю
• ку́хня (kitchen) -> на ку́хню
• If the noun ends in a soft sign -ь, the ending does not change.
• пло́щадь (square) -> на пло́щадь

Let's Practice with Verbs
The two most common verbs of motion are идти́ (to go on foot) and е́хать (to go by vehicle).

🚶 Идти́ (to go on foot, unidirectional)
я иду́
ты идёшь
он/она́ идёт
мы идём
вы идёте
они́ иду́т

🚗 Е́хать (to go by vehicle, unidirectional)
я е́ду
ты е́дешь
он/она́ е́дет
мы е́дем
вы е́дете
они́ е́дут

Putting It All Together: Example Sentences
✅ А́нна идёт в шко́лу. (Anna is walking to school.)

• шко́ла is feminine, ends in -а -> шко́лу
  ✅ Ива́н е́дет на рабо́ту. (Ivan is driving to work.)
• рабо́та is feminine, ends in -а -> рабо́ту
  ✅ Мы идём в теа́тр. (We are walking to the theater.)
• теа́тр is masculine, inanimate -> no change

Summary
To talk about going somewhere:

1. Ask the question Куда́? (Where to?).
2. Choose a verb of motion, like идти́ or е́хать.
3. Choose the correct preposition: в (enclosed spaces) or на (open spaces/events).
4. Change the noun (your destination) to the Accusative case. Remember the key rule: feminine nouns ending in -а/-я change to -у/-ю.
