Бронь столика подтверждена.

Here бронь means reservation / booking.

A few useful notes:

• It is very common in everyday speech, especially in restaurants, hotels, and travel.
• It is a bit less formal than бронирование.
• In other contexts, бронь can also mean something completely different, so the context matters. In this sentence, it clearly means a reservation.

So Бронь столика подтверждена is the kind of thing you might see in a message from a restaurant.

Because столика is in the genitive case.

The phrase бронь столика literally works like reservation of a table. After a noun like бронь, Russian often uses the genitive to show what is being reserved.

So:

• столик = table
• столика = of a table

This is very normal noun + genitive structure in Russian.

In restaurant and café contexts, Russian usually says столик, not стол.

Literally, столик is a diminutive form of стол, so it can mean small table, but in practice it is the standard word for a restaurant table.

So:

• стол = table in general
• столик = the usual word for a table in a café/restaurant booking context

That is why бронь столика sounds natural.

Because подтверждена agrees with бронь, which is:

• feminine
• singular

So the form must also be feminine singular.

Compare:

• бронь подтверждена — feminine singular
• заказ подтверждён — masculine singular
• бронирование подтверждено — neuter singular
• данные подтверждены — plural

The ending tells you the gender/number of the thing being confirmed.

It is a short-form passive participle.

That sounds technical, but the important point is this:

• Russian often uses a short passive participle to mean is confirmed, is done, is prepared, is closed, etc.
• It describes the resulting state of something.

So подтверждена means something like:

• is confirmed
• has been confirmed

Very common similar patterns are:

• Заказ готов. — The order is ready.
• Оплата получена. — Payment has been received.
• Бронь подтверждена. — The reservation is confirmed / has been confirmed.

Russian usually omits the verb to be in the present tense.

So instead of saying something like Бронь есть подтверждена, Russian simply says:

• Бронь подтверждена.

This is normal.

English needs is or has been, but Russian does not.

So the sentence is not missing anything. It is already complete and natural.

Yes, it is effectively passive in meaning.

The focus is on the reservation and its state, not on who confirmed it.

So the idea is:

• The reservation has been confirmed rather than
• Someone confirmed the reservation

If you wanted an active version, it might be something like:

• Мы подтвердили бронь столика. — We confirmed the table reservation.

But the passive-style version is much more natural for system messages, notifications, and formal service communication.

Yes. That is correct and a bit more formal.

Compare:

• Бронь столика подтверждена — more everyday, shorter, very common in service language
• Бронирование столика подтверждено — more formal, more neutral, slightly more official

Notice that with бронирование, the participle changes too:

• бронирование is neuter
• so you get подтверждено, not подтверждена

Both are correct; the first one sounds more conversational and natural in many real-life contexts.

Yes. Russian word order is flexible.

You could also say:

• Подтверждена бронь столика.

This still means the same thing, but the emphasis is a little different. Starting with подтверждена puts more focus on the fact of confirmation.

Still, for a neutral message or notification, Бронь столика подтверждена is very natural.

Both can be understood, but бронь столика is the more standard compact phrase.

Roughly:

• бронь столика = reservation of a table
• бронь на столик = reservation for a table

The version with the genitive, бронь столика, is very common as a fixed expression.

You may also hear other natural variants, for example:

• бронь на двоих
• бронь на вечер
• бронь столика в ресторане

So Russian can use different patterns depending on what detail is being added.

Not with the same meaning.

• Бронь столика подтверждена = the reservation has been confirmed
• Столик забронирован = the table is reserved
• Столик подтверждён sounds odd in most situations, because usually you confirm the booking, not the table itself

So if you want to talk about the reservation being confirmed, the original sentence is the right way to do it.

The stress is:

• бронь
• сто́лика
• подтверждена́

A rough pronunciation guide:

• бронь ≈ bron'
• сто́лика ≈ STO-li-ka
• подтверждена́ ≈ pat-tverzh-de-NA

The final stress in подтверждена́ is especially important. English speakers often want to stress an earlier syllable, but the natural stress is at the end.

Because Russian normally uses the short form after the noun in this kind of predicate sentence.

So:

• Бронь подтверждена. — correct, natural
• Бронь подтвержденная. — not natural here

The full form подтверждённая is usually used more like an adjective before a noun or in a more expanded phrase, for example:

• подтверждённая бронь
• бронь, подтверждённая менеджером

But when the meaning is simply The reservation is confirmed, Russian prefers the short form: подтверждена.
