Зарядна станція працює вдома.

Because зарядна is an adjective modifying станція, and it must agree with it in gender, number, and case.

• станція is feminine
• singular
• nominative case here, because it is the subject of the sentence

So the adjective also takes the feminine singular nominative form:

• masculine: зарядний
• feminine: зарядна
• neuter: зарядне

So зарядна станція is the correct form for charging station.

Станція is in the nominative singular.

That is because it is the subject of the sentence — the thing that works / operates. In Ukrainian, subjects are normally in the nominative case.

So in Зарядна станція працює вдома, the subject is зарядна станція.

Here працює means something like works, functions, or operates.

It comes from the verb працювати.

For people, працювати often means to work in the sense of having a job.
For machines, devices, or systems, it often means to function / to be operating.

So in this sentence, працює does not mean the charging station is doing a job like a person. It means it is working properly or operating.

Працює is the 3rd person singular present tense form of працювати.

A few present-tense forms are:

• я працюю — I work / am working
• ти працюєш — you work
• він/вона працює — he/she/it works
• ми працюємо — we work
• ви працюєте — you work
• вони працюють — they work

So працює matches станція, which is a singular noun.

Вдома is the usual adverb meaning at home.

It is the most natural choice when you mean that something happens at someone’s home in a general sense.

By contrast, у домі means more literally in the house / in the building. That focuses more on physical location inside a structure.

So:

• працює вдома = works at home
• працює у домі = works in the house

In many contexts, вдома sounds more idiomatic.

Yes. Вдома is written as one word.

It is a fixed adverb meaning at home. English speakers often expect something more like in home or at house, but Ukrainian uses this single-word adverb.

You may also hear дома, especially in speech, but вдома is the standard and safest form for learners.

Yes. Ukrainian word order is more flexible than English word order.

The neutral order here is:

• Зарядна станція працює вдома.

But you could also say:

• Вдома працює зарядна станція.
• Працює вдома зарядна станція.

These alternatives may change the focus or emphasis, but the basic meaning stays the same.

English relies heavily on word order for grammar. Ukrainian relies more on endings, so word order is often used for style, emphasis, or topic-focus.

Because Ukrainian has no articles.

English says:

• a charging station
• the charging station

Ukrainian usually just says:

• зарядна станція

Context tells you whether it should be understood as a or the in English.

That is completely normal in Ukrainian, and learners should get used to nouns appearing without any article.

Yes. Станція is a general word meaning station, and its exact meaning depends on context.

For example, it can be used in phrases like:

• залізнична станція — railway station
• пожежна станція — fire station
• зарядна станція — charging station

So the adjective before it tells you what kind of station it is.

Usually вдома means at home in the general sense of being in one’s home environment.

It does not have to mean only a person is at home. Devices, activities, and work can also be described this way if they are used or functioning in a home setting.

So in this sentence, вдома means the charging station works in a home environment / at home, not necessarily in some special technical location.
