Пекарский камень уже горячий.

In Russian, the present tense of to be is usually omitted.

So:

• Пекарский камень уже горячий.
• literally: Baking stone already hot

but it means:

• The baking stone is already hot.

This is completely normal in Russian. You do not need to add a word for is in sentences like this.

Уже means already.

In this sentence, it comes before горячий:

• Пекарский камень уже горячий.

That placement is very natural. Russian word order is fairly flexible, but уже is often placed right before the word or idea it modifies.

Possible variations are:

• Уже горячий пекарский камень — less neutral, more descriptive
• Пекарский камень горячий уже — possible in speech, often with special emphasis

The given order is the most neutral way to say The baking stone is already hot.

Because камень is:

• masculine
• singular
• nominative case

The adjective must agree with the noun, so it also takes the masculine singular nominative form:

• горячий = masculine singular nominative
• горячая = feminine singular nominative
• горячее = neuter singular nominative
• горячие = plural nominative

Since камень is masculine, the correct form is горячий.

Пекарский is an adjective meaning something like baker’s or used for baking.

So:

• пекарский камень = baking stone / baker’s stone

This is just the standard adjective used with this noun in this context. Russian often forms adjectives from nouns, and those adjective choices are lexical: you usually learn them as fixed vocabulary.

It is best to memorize:

• пекарский камень = baking stone

as a whole phrase.

It is in the nominative case, because it is the subject of the sentence.

You can tell from the forms:

• пекарский — masculine singular nominative
• камень — masculine singular nominative

The sentence is basically structured like:

• [subject] + [already] + [predicate adjective]

So:

• Пекарский камень = the subject
• горячий = describes the subject

Russian has no articles like the and a/an.

So:

• камень can mean a stone, the stone, or just stone, depending on context.

In this sentence, English naturally uses the:

• The baking stone is already hot.

But Russian simply says:

• Пекарский камень уже горячий.

The listener understands whether it is definite or indefinite from the situation.

Here горячий is a full adjective used as part of the predicate.

It agrees with камень in gender, number, and case, and it describes the current state of the stone:

• камень горячий = the stone is hot

Russian often uses full adjectives this way in present-tense sentences.

You may also learn short-form adjectives later, but горячий here is the normal, straightforward form for a beginner to recognize.

It is worth noticing because it is a masculine noun ending in -ь, which can surprise learners.

Dictionary form:

• камень = stone

Even though it ends in -ь, it is masculine, not feminine.

Some other forms are:

• nominative singular: камень
• genitive singular: камня
• dative singular: камню
• instrumental singular: камнем
• nominative plural: камни

So yes, it is a noun you should memorize carefully.

A helpful approximate pronunciation is:

• pee-KAR-skee KAH-men' oo-ZHEH ga-RYA-chee

A few notes:

• ж in уже sounds like the s in measure
• ч in горячий sounds like ch
• the final -ий in горячий is pronounced roughly like -ee
• ь in камень is a soft sign; it softens the preceding consonant

If you want to sound natural, stress is important:

• пека́рский
• каме́нь
• уже́
• горя́чий

Yes, but it changes the feel.

• Пекарский камень уже горячий. = neutral, standard
• Пекарский камень горячий уже. = possible, but more marked; it can sound like you are emphasizing already, often in conversation

Russian word order is flexible, but not random. Changing the order usually changes emphasis, not the basic meaning.

For a learner, the original sentence is the best version to use first.

No.

• горячий = hot
• тёплый = warm

So if the baking stone has fully heated up, горячий makes sense.

Compare:

• Камень тёплый. = The stone is warm.
• Камень горячий. = The stone is hot.

That difference is the same basic distinction as in English.

Yes, depending on context.

Пекарский камень is commonly understood as a baking stone, and in everyday English that is often a pizza stone.

So the exact English translation may vary slightly:

• The baking stone is already hot.
• The pizza stone is already hot.

The Russian phrase itself does not force only one of those translations; context tells you what kind of baking stone is meant.

The pattern is:

• noun phrase + уже + adjective

More specifically:

• Пекарский камень = subject
• уже = adverb
• горячий = predicate adjective

So this is a very common Russian structure:

• Суп уже горячий. = The soup is already hot.
• Чай уже холодный. = The tea is already cold.
• Хлеб уже готовый. = The bread is already ready.

It is a useful pattern to learn early because Russian uses it all the time.
