Банкомат чорний.

In Ukrainian, the present-tense verb to be is usually left out in simple statements like this.

So:

• Банкомат чорний. = The ATM is black.

This is completely normal Ukrainian.
If you translated word-for-word into English, it would look like:

• ATM black

But in natural English, you need is, while Ukrainian usually does not in the present tense.

Because чорний is an adjective, and it must agree with the noun банкомат in:

• gender
• number
• case

Here, банкомат is:

• masculine
• singular
• nominative

So the adjective also takes the masculine singular nominative form:

• чорний

Compare:

• чорний банкомат — masculine
• чорна машина — feminine
• чорне вікно — neuter
• чорні банкомати — plural

A very common clue in Ukrainian is the noun ending.

Банкомат ends in a consonant, and nouns ending in a consonant are usually masculine.

So:

• банкомат → masculine

Because it is masculine, the adjective must match:

• банкомат чорний

This is a useful pattern to remember, although there are some exceptions elsewhere in the language.

It is in the nominative case.

This sentence is simply naming the subject and describing it:

• банкомат = the subject
• чорний = a description of the subject

That is why both words are in the nominative:

• банкомат
• чорний

If the noun changed case in a different sentence, the adjective would change too.

Yes, you can say чорний банкомат.

Both word orders are possible, but they are used a little differently.

• чорний банкомат often sounds like a black ATM as a noun phrase
• банкомат чорний sounds more like the ATM is black, with focus on the description

So in your sentence:

• Банкомат чорний. = a full statement

But:

• Чорний банкомат = usually just a phrase, not a complete sentence by itself unless used in a special context

Word order in Ukrainian is more flexible than in English, and it often affects emphasis rather than basic meaning.

Yes. Банкомат is the standard and very common word for ATM / cash machine.

It is widely used in everyday Ukrainian.

You may also see it in different forms depending on case, for example:

• банкомата
• банкомату
• банкоматом

But the basic dictionary form is:

• банкомат

A simple pronunciation guide is:

• банкомат → bahn-koh-MAT
• чорний → CHOR-nyy

Approximate stress:

• банкома́т
• чо́рний

A few sound notes:

• ч sounds like ch in chair
• о is a clear o
• и in чорний is not exactly English ee or ih; it is a Ukrainian vowel pronounced farther back in the mouth
• й at the end helps create the -yy / -y quality

Because the adjective must match the noun’s gender.

Here are the forms:

• чорний — masculine
• чорна — feminine
• чорне — neuter
• чорні — plural

Since банкомат is masculine, the correct form is:

• чорний

So these would be correct:

• банкомат чорний
• машина чорна
• вікно чорне
• банкомати чорні

Yes, in context it can carry that kind of idea, because чорний is a predicate adjective describing the noun.

The main idea is simply that the ATM has the quality black. English may phrase that as:

• The ATM is black
• sometimes, depending on context, The ATM is the black one

But grammatically, the Ukrainian sentence is just a normal descriptive sentence with an omitted present-tense to be.

Yes. Банкомат чорний. is a perfectly possible short sentence.

Ukrainian often allows very concise statements, especially when the context is already clear. For example, someone might be distinguishing one ATM from another:

• Банкомат чорний, а термінал сірий.
• The ATM is black, and the terminal is gray.

So this kind of short sentence is natural, especially in descriptions, exercises, labels, or simple spoken context.

In modern Ukrainian, for a normal present-tense sentence, you usually do not add a present form of to be.

So the natural version is simply:

• Банкомат чорний.

If you want to talk about the past or future, then forms of to be appear:

• Банкомат був чорний. — The ATM was black.
• Банкомат буде чорний. — The ATM will be black.

So the absence of is is specifically a feature of the present tense.
