Прокурор проверил документы.

Because проверил is a perfective past form, from the verb проверить. Perfective verbs usually present an action as completed or as a whole.

So:

• Прокурор проверил документы. = The prosecutor checked the documents / has checked the documents.
• Прокурор проверял документы. = The prosecutor was checking the documents / checked the documents (with more focus on process, repetition, or incompleteness depending on context)

In this sentence, the speaker presents the checking as a finished action.

The dictionary form is проверить.

Here is the breakdown:

• проверить = to check, to inspect, to verify
• проверил = masculine singular past tense form of that verb

Russian past tense forms are based on gender and number:

• проверил = he checked
• проверила = she checked
• проверило = it checked
• проверили = they checked

Since прокурор is a masculine noun, the verb appears as проверил.

Документы is the accusative plural form of документ.

The verb проверить normally takes a direct object, and direct objects often go into the accusative case.

Singular:

• документ = document
• проверил документ = checked a/the document

Plural:

• документы = documents
• проверил документы = checked the documents

A useful detail: for inanimate masculine plural nouns, the accusative plural is usually the same as the nominative plural. So here:

• nominative plural: документы
• accusative plural: документы

That is why the form does not change.

You know from the sentence structure and the verb.

In Прокурор проверил документы:

• Прокурор is the subject: the person doing the action
• проверил is the verb
• документы is what was checked, so it is the direct object

Even though документы looks the same in nominative plural and accusative plural, its function here is object, so it is accusative.

Russian has no articles like a/an or the.

So Прокурор проверил документы could mean:

• The prosecutor checked the documents
• A prosecutor checked the documents

Which one sounds best depends on context. English requires an article, but Russian usually leaves that information unstated unless context makes it clear.

Usually yes: прокурор means prosecutor, especially in a legal or official context.

Depending on the legal system and translation style, it can sometimes be rendered as:

• prosecutor
• public prosecutor
• sometimes something close to state prosecutor

But prosecutor is the standard meaning.

Yes, the word order can change. Russian word order is more flexible than English because case endings help show grammatical roles.

The neutral order here is:

• Прокурор проверил документы.

But you could also say:

• Документы проверил прокурор.
• Проверил прокурор документы.

These alternatives are grammatical, but they change emphasis or information focus.

For example:

• Прокурор проверил документы. = neutral statement
• Документы проверил прокурор. = emphasizes that it was the documents that were checked, or that it was the prosecutor who checked them

So the original sentence is the most straightforward, neutral version.

A simple stress guide:

• прокуро́р
• прове́рил
• докуме́нты

So the sentence is:

прокуро́р прове́рил докуме́нты

Approximate pronunciation for an English speaker:

• pra-koo-ROR
• pra-VYER-eel
• da-ka-MYEN-ty

A few notes:

• Unstressed о often sounds more like a
• Russian р is rolled or tapped
• Stress matters a lot in Russian, so learning it with each word is important

The aspect pair is:

• проверять = imperfective
• проверить = perfective

Compare:

• Прокурор проверял документы. = The prosecutor was checking / checked the documents
• Прокурор проверил документы. = The prosecutor checked / has checked the documents

In many cases:

• imperfective focuses on process, repetition, or general fact
• perfective focuses on completion or result

Because проверить is perfective, it does not have a true present tense meaning. For a present action, Russian uses the imperfective verb проверять.

So:

• Прокурор проверяет документы. = The prosecutor is checking / checks the documents

If you use the perfective future:

• Прокурор проверит документы. = The prosecutor will check the documents

So the forms are:

• проверяет = present, imperfective
• проверил = past, perfective
• проверит = future, perfective

In Russian past tense, the verb agrees with the subject in gender and number.

Here, прокурор is a masculine noun, so the verb is проверил.

In many cases, grammatical gender matches real-world sex for people:

• прокурор проверил = a male prosecutor checked
• if speaking about a female prosecutor, modern usage can vary:
  • often still прокурор проверил, if the noun is treated grammatically as masculine in formal style
  • or прокурор проверила, if agreement follows the actual female person

Russian job titles can be tricky when referring to women, so usage depends on style, register, and speaker preference.

Yes. Проверить has a meaning range that includes:

• check
• inspect
• verify

The best English translation depends on context.

For example:

• physically looking through papers → checked the documents
• confirming that they are valid or correct → verified the documents

So if you only see the Russian sentence by itself, checked the documents is a natural general translation, but verified the documents may also be correct in the right context.
