Ist das Frühstück im Preis enthalten?

Because this is a yes/no question in German. In German, yes/no questions usually put the verb first:

• Das Frühstück ist im Preis enthalten. = Breakfast is included in the price.
• Ist das Frühstück im Preis enthalten? = Is breakfast included in the price?

So the word order changes mainly to show that it is a question.

Frühstück is a neuter noun in German, so its article is das.

• das Frühstück = the breakfast / breakfast

You need das here because it is the subject of the sentence:

• Ist das Frühstück ... enthalten?

Frühstück literally means breakfast.

In this sentence, it usually refers to the hotel breakfast or breakfast as part of a booking. German often uses the article where English might not:

• Ist das Frühstück im Preis enthalten?

In natural English, we usually just say Is breakfast included in the price?, even though German says the breakfast.

im is a contraction of in dem:

• in dem → im

So:

• im Preis = in the price

This contraction is very common in German.

It is im Preis because in here describes a state or inclusion, not movement.

German two-way prepositions like in can take:

• dative for location/state
• accusative for movement/direction

Here, breakfast is included within the price, so German uses the dative:

• im Preis = in dem Preis

You could say in dem Preis, but im Preis is the normal contracted form.

Here enthalten means included.

In this sentence, it works like an adjective/past participle:

• enthalten = included, contained

So:

• im Preis enthalten = included in the price

You will often see this expression in hotels, travel, and product descriptions.

It comes from a verb, but in this sentence it functions like a past participle used predicatively, which is very similar to an adjective.

Compare:

• Das Frühstück ist enthalten. = The breakfast is included.
• Das ist im Preis enthalten. = That is included in the price.

So learners often think of it as included, which is the most useful way to understand it here.

German often puts this kind of element at the end when used with sein.

The structure is:

• Ist
  • subject + other information + enthalten

So:

• Ist / das Frühstück / im Preis / enthalten?

This end position is very normal in German.

Usually, Ist das Frühstück im Preis enthalten? sounds more natural in this context.

Without the article, Frühstück can sometimes be used in a more general sense, but in hotel and booking situations German very often uses:

• das Frühstück

So if you are asking whether the breakfast that belongs to the stay is included, das Frühstück is the safest and most idiomatic choice.

Yes. Preis is a masculine noun:

• der Preis = the price

After in dem, it becomes:

• dem Preis

And because in dem contracts to im, you get:

• im Preis

The statement form is:

• Das Frühstück ist im Preis enthalten.

This means:

• Breakfast is included in the price.

So the only main change for the yes/no question is that ist moves to the front:

• Das Frühstück ist ...
• Ist das Frühstück ...?

Yes, very common. You might see or hear similar sentences such as:

• Ist WLAN im Preis enthalten? = Is Wi-Fi included in the price?
• Sind Handtücher im Preis enthalten? = Are towels included in the price?
• Ist die Kurtaxe im Preis enthalten? = Is the tourist tax included in the price?

So im Preis enthalten is a very useful phrase to learn.

Roughly, Frühstück sounds like FRUE-shtewk, but the vowels are important:

• Früh- has ü, a sound English does not have exactly
• -stück also contains ü

A rough guide:

• Frühstück ≈ FRÜH-shtük

Also note:

• st at the start of a syllable in standard German is usually pronounced sht
• So Stück sounds like shtük, not stük
