Каменка ещё горячая.

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

So:

• Каменка ещё горячая. = The heater/stove is still hot.

Russian does not normally say есть here. Using есть in a sentence like this would sound unnatural for a basic statement of description.

Compare:

• Она усталая. = She is tired.
• Вода холодная. = The water is cold.

But in the past or future, Russian does use forms of to be:

• Каменка была горячая. = The heater was hot.
• Каменка будет горячая. = The heater will be hot.

Because it agrees with Каменка, which is feminine singular.

Russian adjectives change their endings to match the noun’s:

• горячий — masculine
• горячая — feminine
• горячее — neuter
• горячие — plural

So here:

• Каменка = feminine singular
• therefore горячая must also be feminine singular

This is called agreement.

A very common clue in Russian is the noun ending.

Most nouns ending in -а or -я are feminine, and каменка follows that pattern.

Also, the adjective confirms it:

• горячая is feminine
• so the noun it describes must also be feminine here

So even if you were unsure at first, the adjective helps you identify the gender.

It is in the nominative case.

Why?

Because Каменка is the subject of the sentence — the thing being described.

The basic structure is:

• Каменка — subject
• ещё — adverb
• горячая — predicate adjective / description

So this is a simple nominative subject with a description.

Here ещё means still.

So:

• Каменка ещё горячая. = The heater is still hot.

This is a very common use of ещё.

But ещё can also mean other things in other contexts, such as:

• more
• another
• yet

For example:

• ещё чай = more tea
• ещё один = one more / another one

So the exact meaning depends on context. In this sentence, still is the natural meaning.

Yes. Всё ещё also means still, and it can sound a bit more explicit.

Compare:

• Каменка ещё горячая.
• Каменка всё ещё горячая.

Both are correct.

Very roughly:

• ещё = still
• всё ещё = still, and often a bit more emphatic, like still even now

In everyday Russian, both are common.

Russian has both long-form and short-form adjectives.

For hot:

• long form: горячий / горячая / горячее / горячие
• short form: горяч / горяча / горячо / горячи

In modern everyday speech, the long form is usually more neutral and common here:

• Каменка ещё горячая.

The short form is possible:

• Каменка ещё горяча.

But that sounds more literary, formal, or stylistically marked. For a normal everyday statement, горячая is the more natural choice.

Yes, Russian word order is flexible, but the sentence as written is the most neutral.

• Каменка ещё горячая. — neutral, natural
• Каменка всё ещё горячая. — also very natural
• Ещё каменка горячая. — possible only in special context, but not the normal way to say it
• Горячая ещё каменка. — very marked, poetic, or contrastive

So if you are learning, the safest pattern is:

• subject + ещё + adjective

That gives you a normal, natural sentence.

Russian has no articles like a or the.

So Каменка ещё горячая can mean:

• The heater is still hot
• A heater is still hot

Which one sounds right in English depends on context.

Russian leaves that to the situation rather than using a separate word.

Yes, in this sentence it is capitalized because it comes at the beginning of the sentence.

As a common noun, it would normally be lowercase in the middle of a sentence:

• Эта каменка ещё горячая. = This heater is still hot.

So you should not assume it is a proper name just because it starts with a capital letter here.

In careful writing and learning materials, ё is usually written as ё:

• ещё

But in many real-world texts, Russians often write е instead:

• еще

Even when it is written with е, it is still usually understood and pronounced as ещё.

For learners, it is best to remember:

• ё has the yo sound
• ещё is pronounced with ё, even if you sometimes see еще in everyday writing
