Електрик перевіряє дріт, запобіжник і автоматичний вимикач.

Перевіряє is the 3rd person singular present form of перевіряти.

It can mean either:

• checks
• is checking

Ukrainian present tense with an imperfective verb often covers both the simple present and the present continuous. So the exact English translation depends on context.

They are all direct objects, so they are in the accusative case. But there is an important rule:

• for masculine singular inanimate nouns, the accusative looks the same as the nominative

That is why you see:

• дріт
• запобіжник
• вимикач

with no visible change.

• Електрик is in the nominative because it is the subject.
• дріт, запобіжник, and автоматичний вимикач are in the accusative because they are the things being checked.

Even though the object nouns look unchanged, they are still grammatically accusative.

Автоматичний is an adjective modifying вимикач. In Ukrainian, adjectives must agree with the noun in:

• gender
• number
• case

Since вимикач is masculine singular inanimate, the adjective also appears in the matching masculine singular form: автоматичний.

Yes. Both і and та can mean and.

In this sentence, і is perfectly natural. Та is also possible, but і is the most basic and common choice. Ukrainian sometimes switches between і and та for style or smoother sound.

No, Ukrainian word order is more flexible than English word order.

Електрик перевіряє дріт, запобіжник і автоматичний вимикач is the neutral, standard order:

• subject
• verb
• objects

You can rearrange parts of the sentence for emphasis, but this version is the most straightforward one for a learner to use.

A rough English-friendly spelling is pereviryaye.

The ending -яє sounds roughly like -ya-ye. So the whole word is approximately:

pe-re-vi-rya-ye

This is only an approximation, but it helps show that the last part is not just one syllable.

Електрик is grammatically masculine and is the standard dictionary form. In context, it usually refers to a male electrician, or it can be used generically.

A feminine form електрикиня also exists in modern Ukrainian if you want to make it specifically female.
