Russian phrasebook

Приве́т!

Hi!

Informal, and only for people you already know: friends, family, children, people your own age in a relaxed setting. Never use it with an official, a doctor or a stranger.

Здра́вствуйте!

Hello!

The safe default with any adult you do not know. The first в is silent, so the word is shorter than it looks: [ˈzdrastvʲɪtʲə].

До́брое у́тро!

Good morning!

До́брый день!

Good afternoon!

Also the standard greeting in shops and offices at any time after midday — it is not restricted to the afternoon.

До́брый ве́чер!

Good evening!

До свида́ния!

Goodbye!

Literally "until the meeting". Neutral and always correct; a stranger would not expect Пока from you.

Пока́!

Bye!

Informal only, like Привет. With someone you address as вы, say До свидания.

До за́втра!

See you tomorrow!

Споко́йной но́чи!

Good night!

Как дела́?

How are things?

Informal, because it uses no вы form at all. The formal equivalent is Как ваши дела? — and either way Russians expect a short answer, not a full report.

Как ва́ши дела́?

How are you?

The polite version of Как дела? Use it with anyone you address as вы.

Хорошо́, спа́сибо. А у вас?

Fine, thanks. And you?

Literally "and at you?" — Russian asks after someone's state with у + genitive, not with a repeated Как вы?

Рад вас ви́деть!

Good to see you!

A man says рад; a woman says рада. The word for "glad" agrees with the speaker, never with the person being greeted.

Давно́ не ви́делись!

Long time no see!

Literally "we have not seen each other for a long time". The reflexive -сь is what makes it mutual; видеть alone would mean you failed to see something.

Добро́ пожа́ловать!

Welcome!

A fixed greeting to a guest or an arrival. It is not the answer to спасибо — that is Пожалуйста or Не за что.

Меня́ зову́т А́нна.

My name is Anna.

Literally "they call me Anna". Меня is the accusative of я and Анна stays in the nominative — the construction has no subject "I" in it at all.

Как вас зову́т?

What is your name?

The вы form. Ask it of any adult you have just met.

Как тебя́ зову́т?

What's your name?

The ты form, for children and for people who have offered to switch.

О́чень прия́тно!

Pleased to meet you!

Literally "very pleasant". Said once, right after names are exchanged.

Я из А́нглии.

I am from England.

The country goes in the genitive after из: из Англии, из России, из Италии. The "am" is simply absent, which is normal in the present tense.

Отку́да вы?

Where are you from?

Откуда asks about origin; где asks about location. Mixing them up is the most common beginner mistake here.

Где вы живёте?

Where do you live?

Я живу́ в Ло́ндоне.

I live in London.

After в meaning "in", a city takes the prepositional case: в Лондоне, в Москве. The nominative is a hard error.

Ско́лько вам лет?

How old are you?

Literally "how many years to you?". Age is something a person HAS (dative + лет), never something they ARE.

Мне два́дцать пять лет.

I am twenty-five.

Literally "to me twenty-five years". The number governs the noun: 1 год, 2–4 года, 5 and above лет. The verb "to be" does not appear.

Я не говорю́ по-ру́сски.

I do not speak Russian.

The adverb is по-русски, with a final -и. Russian does not need "the Russian language" here, though я не говорю по-русски and я не говорю на русском are both heard.

Я немно́го говорю́ по-ру́сски.

I speak a little Russian.

A much better opener than an apology: it invites the other person to slow down rather than switch to English.

Кто вы по профе́ссии?

What do you do for a living?

Literally "who are you by profession?". The answer is a noun in the nominative: Я врач, Я учитель.

Чем вы занима́етесь?

What do you do?

The -ся verb means "occupy yourself with"; чем is the instrumental of что, so the literal sense is "with what do you occupy yourself?".

Спа́сибо!

Thank you!

Большо́е спа́сибо!

Thank you very much!

Пожа́луйста.

Please. / You're welcome.

One word does both jobs: "please" after a request and "you're welcome" after спасибо. Which one it is depends entirely on where it sits.

Не за что!

Don't mention it.

Literally "nothing for". Warm and slightly casual; in a formal exchange say Пожалуйста instead.

Извини́те.

Excuse me. / Sorry.

Covers both "sorry" and "excuse me, could you…". The ты form is Извини.

Прости́те, пожа́луйста.

I'm sorry.

Stronger than Извините; add пожалуйста for a real apology rather than a nudge past someone in the metro.

Извини́.

Sorry.

Only to someone you address as ты.

Прошу́ проще́ния.

I beg your pardon.

The most formal apology available, and the right one after bumping into a stranger or interrupting.

Бу́дьте добры́.

Could you kindly…

Literally "be so good". Placed before or after a request: Будьте добры, чашку чая. It is warm without being familiar.

Бу́дьте любе́зны.

Would you be so kind.

A shade more official than Будьте добры — the register of a reception desk or a written request.

Не могли́ бы вы мне помо́чь?

Could you help me?

The бы makes it a request rather than a question about ability. Without бы, Не могли вы мне помочь? sounds like an accusation.

Скажи́те, пожа́луйста.

Excuse me… (before a question)

The standard way to stop a stranger in the street. It is always the вы imperative; Скажи is for children.

Мо́жно?

May I?

One word for "may I?", "is it allowed?", "can I come in?". Answer with Можно or Нельзя.

Благодарю́ вас.

I thank you.

A formal, slightly written alternative to Спасибо, common in service exchanges and in letters.

Да, коне́чно.

Yes, of course.

Нет, спа́сибо.

No, thank you.

The polite refusal. Plain Нет on its own is not rude, but it is blunt.

Коне́чно!

Of course!

Мо́жет быть.

Maybe.

Literally "it may be". Impersonal, so the verb never agrees with anything.

Ничего́ стра́шного.

It doesn't matter. / No worries.

Literally "nothing terrible". The standard reply when someone apologises for something small.

Всё равно́.

It makes no difference.

Also used as a discourse connector, "anyway". Print the ё: все равно without it means "everyone equally".

Так себе́.

So-so.

The honest answer to Как дела? when things are mediocre.

Что но́вого?

What's new?

Я не зна́ю.

I do not know.

не goes immediately before the verb and never merges with it.

Я понима́ю.

I understand.

Всё в поря́дке.

Everything is fine.

Literally "everything is in order". The commonest reassurance there is.

Пра́вда?

Really?

Наве́рное.

Probably.

Не ва́жно.

It doesn't matter.

Мне пора́.

I have to go.

Literally "it is time for me" — an impersonal construction with the dative. The polite way to leave a conversation.

Кто э́то?

Who is this?

Кто always takes a masculine singular verb or adjective, whatever the person's gender: Кто это пришла? is wrong; Кто это пришёл? is right.

Что э́то?

What is this?

Где э́то?

Where is that?

Где asks where something is. For where something is going, use Куда.

Куда́ вы идёте?

Where are you going?

Куда is the accusative of motion, где the prepositional of rest. This pair is the single most useful distinction in Russian place words.

Когда́?

When?

Почему́?

Why?

Ско́лько э́то сто́ит?

How much is this?

A fixed chunk — learn it whole. Сколько governs the genitive: сколько времени, сколько рублей, сколько человек.

Вы говори́те по-англи́йски?

Do you speak English?

A yes/no question uses exactly the same words as the statement. Only the intonation rises, sharply, on the stressed syllable.

Э́то свобо́дно?

Is this free?

Asked about a seat, a table or a taxi. Свободно is the neuter short form, so it needs no noun to agree with.

Не могли́ бы вы повтори́ть?

Could you say that again?

The formal clarification request, and the one worth memorising first: it works with anyone.

Повтори́, пожа́луйста.

Say that again, please.

The ты imperative. Use only with children or close acquaintances.

Как э́то бу́дет по-ру́сски?

How do you say this in Russian?

Literally "how will this be in Russian?". The future tense is idiomatic here; the present would sound like a question about a fact.

Что зна́чит э́то сло́во?

What does this word mean?

значит is the fixed third-person form used in definitions; it does not agree with the word being defined.

Вы меня́ понима́ете?

Do you understand me?

меня is the accusative of я. Note that "I understand you" would be Я вас понимаю — the pronoun changes case, the verb does not.

Вы не подска́жете, где метро́?

Could you tell me where the metro is?

A negative yes/no question is the polite Russian request form, and the subordinate clause keeps statement word order: где метро, not где находится метро ли.

Мо́жно спроси́ть?

May I ask?

The impersonal можно plus an infinitive is how Russian asks permission without naming who is allowed.

Оди́н, два, три, четы́ре, пять.

One, two, three, four, five.

один has three gender forms — один (m), одна (f), одно (n) — and they must agree with the noun being counted.

Шесть, семь, во́семь, де́вять, де́сять.

Six, seven, eight, nine, ten.

Два́дцать, три́дцать, пятьдеся́т, сто.

Twenty, thirty, fifty, a hundred.

Note the soft sign inside the teens and the tens: двадцать, тридцать, пятьдесят. It marks the original two words, "two tens", "five tens".

Ты́сяча рубле́й.

A thousand roubles.

After 5 and above, and after тысяча, the counted noun goes in the genitive plural: пять рублей, тысяча рублей.

Ско́лько сто́ит биле́т?

How much is a ticket?

Два ко́фе, пожа́луйста.

Two coffees, please.

два governs the genitive singular, so it is два кофе, not два кофев. кофе is indeclinable and stays the same in every case.

Пять биле́тов, пожа́луйста.

Five tickets, please.

Five and above take the genitive plural: пять билетов. Contrast два билета, три билета — the ending changes with the number, not the noun.

Э́то до́рого.

That's expensive.

Э́то дёшево.

That's cheap.

Always print the ё. дешево would be read as "dye-SHO-vo" by a learner and looks like a typo to a Russian.

Я пла́чу ка́ртой.

I am paying by card.

The instrumental answers "by what means": картой, наличными, переводом.

У меня́ нет нали́чных.

I don't have any cash.

Negated possession is у + genitive + нет, never я не имею. деньги and наличные have no singular.

Да́йте, пожа́луйста, чек.

The receipt, please.

дайте is the вы imperative of дать, a suppletive perfective verb: дам, дашь, даст, дадим, дадите, дадут.

Сда́чи не на́до.

Keep the change.

Literally "no change is needed". не надо is the impersonal way to say something is not wanted; it never changes form.

Ско́лько с меня́?

How much do I owe you?

Literally "how much from me?", with the genitive after с. Very idiomatic at a market stall or in a taxi.

Кото́рый час?

What time is it?

Literally "which hour?". The other, equally common form is Сколько сейчас времени?

Ско́лько сейча́с вре́мени?

What's the time?

времени is the genitive of время, a neuter noun of the -мя type: время, времени, временем, о времени.

Сейча́с полови́на тре́тьего.

It's half past two.

Literally "half of the third". Russian halves point forward to the next hour, so половина третьего is 2.30, never 3.30.

В три часа́.

At three o'clock.

Clock time uses в + accusative, and the numeral decides the noun: в три часа, в пять часов. The hour word is час, not время.

В кото́ром часу́?

At what time?

The rare locative form часу, used only with в when asking the time of an event. В котором час? would be wrong.

Како́й сего́дня день?

What day is it today?

Literally "what day is today?", asking for the day of the week.

Сего́дня понеде́льник.

Today is Monday.

Days of the week are not capitalised in Russian, and the copula is absent: Сегодня понедельник, literally "today Monday".

Сего́дня пя́тое ма́я.

Today is the fifth of May.

A date is an ordinal in the nominative neuter plus the month in the genitive: пятое мая, первое января. The month never takes a preposition.

У́тром, днём, ве́чером, но́чью.

In the morning, in the afternoon, in the evening, at night.

These four are frozen instrumental forms functioning as adverbs. English "in the morning" has no preposition in Russian at all.

Ка́ждый день.

Every day.

каждый agrees with the noun and the noun stays singular: каждый день, каждая неделя.

Че́рез неде́лю.

In a week.

через + accusative means "in" for a point in the future: через час, через две недели.

С понеде́льника по пя́тницу.

Monday to Friday.

с + genitive and по + accusative frame a period: from… through to… inclusive.

У меня́ нет вре́мени.

I have no time.

Literally "at me there is no time". Note the genitive времени after нет.

Сейча́с и́ли пото́м?

Now or later?

Э́то моя́ семья́.

This is my family.

семья is a feminine noun of the -ья type, so the possessive is моя, not мой.

У меня́ есть брат и сестра́.

I have a brother and a sister.

Russian possession is "at me there is": у + genitive + есть. The verb agrees with what is possessed, not with the speaker.

Э́то мой муж.

This is my husband.

Э́то моя́ жена́.

This is my wife.

У меня́ дво́е дете́й.

I have two children.

Collective numerals — двое, трое, четверо — are used with дети and with plural-only nouns, and they take the genitive plural.

Э́то мои́ роди́тели.

These are my parents.

With a plural noun the possessive is мои and the copula disappears, so the whole sentence is just a pointing word and two nouns.

Э́то мой деду́шка и моя́ ба́бушка.

This is my grandfather and my grandmother.

дедушка ends in -а and is grammatically masculine even though it means a woman's or a man's grandfather, so it takes мой.

У вас есть де́ти?

Do you have children?

У меня́ нет дете́й.

I don't have children.

Negating possession drops есть and puts the possessed noun in the genitive plural: нет детей.

Э́то мой друг.

This is my friend (a man).

Э́то моя́ подру́га.

This is my friend (a woman).

подруга can mean a female friend or a girlfriend; the context decides. друг is normally male, though a mixed group is друзья.

Ско́лько челове́к в ва́шей семье́?

How many people are in your family?

After сколько the noun is genitive plural, and человек has the irregular genitive plural человек, not человеков.

Мой сын — студе́нт.

My son is a student.

The em dash appears when both subject and predicate are nouns in the nominative and there is no verb between them.

Э́то моя́ тётя.

This is my aunt.

Always print the ё: тетя without it looks like a typo and would be read as "tye-tya".

Я хочу́ пить.

I am thirsty.

Literally "I want to drink". Russian has no single verb for being thirsty or hungry.

Я хочу́ есть.

I am hungry.

Literally "I want to eat". The same verb есть means both "to eat" and "there is" — only the position tells them apart.

Что вы хоти́те?

What would you like?

хотеть is irregular in the plural: мы хотим, вы хотите, but я хочу, они хотят.

Чай и́ли ко́фе?

Tea or coffee?

кофе is masculine despite ending in -е, so it is этот кофе, хороший кофе.

Да́йте, пожа́луйста, воды́.

Some water, please.

The partitive genitive воды after a request implies "some of it"; accusative воду would mean one specific quantity of water.

Без са́хара, пожа́луйста.

Without sugar, please.

без always takes the genitive: без сахара, без молока, без льда.

Я не ем мя́со.

I don't eat meat.

The direct object stays accusative after a negated verb of eating and drinking; the genitive (я не ем мяса) is also correct but more formal.

Я люблю́ чай с лимо́ном.

I like tea with lemon.

с meaning "with" takes the instrumental: с лимоном, с молоком, с сахаром.

Э́то вку́сно!

This is delicious!

вкусно is the short neuter predicative; it says nothing about any noun and so never agrees.

Э́то сли́шком сла́дко.

This is too sweet.

слишком + short adjective is the standard way to complain politely about food.

Соль и пе́рец, пожа́луйста.

Salt and pepper, please.

A noun on its own with пожалуйста is a complete order in a café; no verb is needed.

Ещё одну́ ча́шку ча́я, пожа́луйста.

Another cup of tea, please.

Two genitives in a row: чашку чая, "a cup of tea". The container is accusative after ещё одну, the contents genitive.

Мне нра́вится ру́сская ку́хня.

I like Russian food.

нравиться takes a dative subject and a nominative object: the food pleases me. Literally "to me Russian cuisine is pleasing".

А что э́то за блю́до?

And what kind of dish is this?

что это за + nominative is the fixed frame for "what sort of…". The за is not a preposition here and never changes.

Сто́лик на дво́их, пожа́луйста.

A table for two, please.

на + accusative expresses capacity: на двоих, на четверых. The genitive forms двоих, четверых only appear with these collective numerals.

У вас есть свобо́дные сто́лики?

Do you have any free tables?

Меню́, пожа́луйста.

The menu, please.

меню is indeclinable and neuter, so it is the same in every case and number.

Мы гото́вы заказа́ть.

We are ready to order.

The short adjective готовы goes with the infinitive; the full form готовые would need a noun to modify.

Что вы посове́туете?

What do you recommend?

посоветовать is perfective, so the form is future in shape but present in meaning: it asks for one recommendation now.

Я бу́ду суп и сала́т.

I will have the soup and a salad.

Using буду with a noun in the accusative is the standard way to order; it is not a future-tense statement about yourself.

Принеси́те, пожа́луйста, ви́лку.

Could you bring a fork, please?

Ещё одну́ буты́лку воды́, пожа́луйста.

Another bottle of water, please.

Э́то бы́ло о́чень вку́сно.

That was delicious.

The past tense needs было here because вкусно is a predicative, not an adjective: literally "it was very tasty".

В э́том блю́де есть оре́хи?

Are there nuts in this dish?

The prepositional case after в answers "in what?": в блюде, в супе, в соусе.

Счёт, пожа́луйста.

The bill, please.

Print the ё: счёт is "the bill", счет is not a word. American "check" is чек, which in Russia means the printed receipt.

Мо́жно оплати́ть ка́ртой?

Can I pay by card?

Обслужи́вание включено́ в счёт?

Is service included?

включено is the short neuter form, agreeing with обслуживание.

Позови́те официа́нта, пожа́луйста.

Could you call the waiter, please?

позвать takes the animate accusative, which for a masculine person equals the genitive: официа+нта, not официант.

Ско́лько сто́ит э́та су́мка?

How much is this bag?

The demonstrative agrees with the noun: эта сумка, этот телефон, это пальто.

Како́й э́то разме́р?

What size is this?

У вас есть тако́й же, но бо́льше?

Do you have the same but bigger?

такой же means "the same", and больше is the comparative of большой. A comparative never takes a case ending, so it is больше, not *большего.

Где приме́рочная?

Where is the fitting room?

приме́рочная is an adjective used as a noun, so it takes the feminine ending to agree with the understood комната.

Мо́жно приме́рить?

Can I try it on?

Э́то мне ма́ло.

It is too small for me.

Literally "this is small to me", with the dative. The same frame gives это мне велико, "it is too big for me".

Э́то сли́шком до́рого.

That is too expensive.

дорого is the short neuter adverb, stressed on the first syllable — so the г here is a real [ɡ], not the [v] of the adjective ending -ого.

Я беру́ э́то.

I will take it.

The imperfective present беру does the work of English "I'll take": aspect, not tense, carries the decision.

Где ка́сса?

Where is the till?

Вы принима́ете ка́рты?

Do you take cards?

Да́йте, пожа́луйста, паке́т.

A bag, please.

Мне ну́жен чек.

I need a receipt.

нужен is the short adjective and agrees with the thing needed: нужен чек, нужна помощь, нужно время, нужны билеты.

Мо́жно верну́ть э́то?

Can I return this?

До кото́рого ча́са вы рабо́таете?

What time do you close?

Literally "until which hour do you work?". до + genitive, and часа is the genitive of час.

Где остано́вка авто́буса?

Where is the bus stop?

The vehicle goes in the genitive after the place: остановка автобуса, станция метро, аэропорт города.

Како́й авто́бус идёт в центр?

Which bus goes to the centre?

идти is for going on foot or by any vehicle seen as moving along a route; a bus and a train both "go", they do not "ride".

Э́тот авто́бус идёт до вокза́ла?

Does this bus go to the station?

до + genitive marks the end point of a journey: до вокзала, до аэропорта.

Оди́н биле́т, пожа́луйста.

One ticket, please.

один agrees in gender with the noun: один билет, одна минута, одно место.

Биле́т до Москвы́, пожа́луйста.

A ticket to Moscow, please.

A ticket TO a place uses до + genitive, not в + accusative: билет до Москвы. This is a fixed government and beginners get it wrong every time.

Ско́лько сто́ит прое́зд?

How much is the fare?

Когда́ отправля́ется по́езд?

When does the train leave?

The reflexive -ся here is not passive but intransitive: the train departs itself, so to speak. отправлять without -ся means "to send something".

С како́й платфо́рмы?

From which platform?

с + genitive is the counterpart of на + prepositional for platforms and stops: поезд с первой платформы.

Где ста́нция метро́?

Where is the metro station?

метро is indeclinable, so it never changes form and never takes a preposition of its own here.

Мне ну́жно вы́йти на сле́дующей остано́вке.

I need to get off at the next stop.

After a verb of stepping off, the stop is prepositional with на: выйти на остановке. The perfective выйти is required because it is one completed action.

Вы́зовите мне такси́, пожа́луйста.

Could you call me a taxi, please?

Останови́те здесь, пожа́луйста.

Stop here, please.

Said from the back seat. The perfective остановите means "bring it to a stop", which is exactly what you want.

Э́то ме́сто свобо́дно?

Is this seat free?

По́езд опа́здывает?

Is the train late?

опаздывать is imperfective and asks about a state of affairs; the perfective опоздать would ask whether it has already missed its slot.

Как пройти́ к музе́ю?

How do I get to the museum?

The dative after к marks movement towards: к музею, к вокзалу, к врачу.

Где нахо́дится вокза́л?

Where is the station?

находиться literally means "find itself" and is the neutral way to ask where something is situated.

Иди́те пря́мо.

Go straight ahead.

The imperative of идти is irregular: иди (ты), идите (вы). There is no "*идьте".

Поверни́те напра́во.

Turn right.

Поверни́те нале́во.

Turn left.

направо and налево are adverbs, so they are invariable; правый and левый are the adjectives and do agree.

Э́то далеко́?

Is it far?

Э́то совсе́м бли́зко.

It is really close.

Иди́те до перекрёстка.

Go as far as the crossroads.

до + genitive marks the limit: до перекрёстка, до угла, до конца улицы.

На светофо́ре поверни́те напра́во.

Turn right at the traffic lights.

A point where something happens takes на + prepositional: на светофоре, на остановке, на углу.

Где пешехо́дный перехо́д?

Where is the pedestrian crossing?

Э́то за у́глом.

It is round the corner.

за + instrumental here means "just beyond": за углом, за домом, за парком.

Ря́дом с ба́нком.

Next to the bank.

рядом с always takes the instrumental, so the bank becomes банком.

Дойди́те до конца́ у́лицы.

Go to the end of the street.

дойти is the perfective of идти with до-, and it means "reach on foot". Two genitives stack up: конца улицы.

Вы не могли́ бы показа́ть на ка́рте?

Could you show me on the map?

показать is perfective; the imperfective показывать would suggest showing repeatedly or for a while.

Я ищу́ апте́ку.

I am looking for a pharmacy.

искать takes the accusative for a concrete thing (аптеку) but the genitive for something abstract or unspecified (помощи, работы).

Где здесь туале́т?

Where is the toilet here?

здесь softens the question — without it, Где туалет? is perfectly correct but very blunt.

Где ближа́йший банкома́т?

Where is the nearest cash machine?

Где по́чта?

Where is the post office?

почта is one of the few feminine places that take на, not в: на почте for where it is, на почту for where you are going. В почте is a hard error.

Где банк?

Where is the bank?

Здесь есть супермарке́т?

Is there a supermarket here?

Музе́й откры́т в понеде́льник?

Is the museum open on Monday?

Days of the week take в + accusative: в понедельник, в субботу. The short form открыт is invariable, so it works for any gender.

Во ско́лько закрыва́ется музе́й?

What time does the museum close?

во rather than в before ско-, and the reflexive -ся makes the verb intransitive: the museum closes itself.

Где вход?

Where is the entrance?

Где вы́ход?

Where is the exit?

вход and выход differ only by prefix, and the prefix carries the whole meaning: в- "in", вы- "out".

Э́то центр го́рода?

Is this the city centre?

Где мо́жно купи́ть воду́?

Where can I buy some water?

Где парк?

Where is the park?

Каки́е достопримеча́тельности здесь есть?

What sights are there here?

A long word but a regular one: the stress stays on the second -а- in every form of достопримечательность.

У вас есть свобо́дные но́мера?

Do you have any rooms free?

номер is stressed on the ending in the plural: номера́, not но́мера.

У меня́ бронь на и́мя Смит.

I have a reservation in the name of Smith.

на + accusative gives the name a booking is held under. Foreign names are normally left undeclined.

Но́мер на одну́ ночь, пожа́луйста.

A room for one night, please.

ночь is a third-declension feminine noun, so the genitive plural is ночей: на три ночи, пять ночей.

Ско́лько сто́ит но́мер за ночь?

How much is a room per night?

Мне ну́жен двухме́стный но́мер.

I need a double room.

двухместный is literally "two-place"; a single room is одноместный номер.

За́втрак включён?

Is breakfast included?

включён is the short masculine form and agrees with завтрак; with a feminine noun it would be включена.

Во ско́лько за́втрак?

What time is breakfast?

Мой но́мер на како́м этаже́?

What floor is my room on?

этаж takes на + prepositional for the floor something is on: на третьем этаже.

Да́йте мне ключ, пожа́луйста.

Could I have the key, please?

В но́мере нет горя́чей воды́.

There is no hot water in the room.

Negated existence puts the noun in the genitive, and the adjective follows it: нет горячей воды, not нет горячую воду.

Кондицио́нер не рабо́тает.

The air conditioning is not working.

не работает is the universal complaint formula: the lift, the shower and the internet all use it.

Мо́жно поменя́ть но́мер?

Can I change rooms?

Во ско́лько вы́езд?

What time is check-out?
