Проверьте документ хорошенько.

Проверьте is the imperative form of the verb проверить, which means to check or to inspect.

So grammatically, it means check!

Because it is from the perfective verb проверить, it usually means check it and complete the action, not just be checking in a general sense.

The ending -те can do two things in Russian:

1. make the command plural: speaking to more than one person
2. make it polite/formal: speaking to one person respectfully

So Проверьте документ хорошенько can mean:

• Check the document carefully — said to several people
• Please check the document carefully — said politely to one person

The informal singular version would be Проверь документ хорошенько.

Here документ is the direct object of the verb check, so it is in the accusative case.

But документ is:

• masculine
• singular
• inanimate

For many masculine inanimate nouns in Russian, the accusative singular looks exactly the same as the nominative singular.

So:

• nominative: документ
• accusative: документ

That is why the form does not change.

Хорошенько means something like:

• thoroughly
• carefully
• properly
• really well

It adds the idea that the checking should be done carefully and completely, not in a quick or careless way.

So the sentence is stronger than just Check the document. It means more like Check the document thoroughly.

Not exactly.

• хорошо usually means well
• хорошенько often means really well, properly, or thoroughly

Хорошенько sounds a bit more expressive and conversational. It often suggests putting in some real care or effort.

Compare:

• Проверьте документ хорошо = check the document well
• Проверьте документ хорошенько = check the document really thoroughly / properly

In this sentence, хорошенько sounds very natural.

This is about aspect, which is very important in Russian.

• проверить = perfective
• проверять = imperfective

Here, the speaker wants one complete action: check the document and finish checking it. That is why Проверьте is used.

If you said Проверяйте, it would sound more like:

• keep checking
• check from time to time
• be checking
• or a more process-oriented instruction

So in a normal one-time command, Проверьте is the natural choice.

It can be either, depending on context and tone.

Russian imperatives often cover both:

• a direct command
• a request
• an instruction

Because Проверьте has the polite/plural -те, it can sound quite normal and polite, especially in professional situations.

If you want to make it softer, you can add пожалуйста:

Проверьте, пожалуйста, документ хорошенько.

That would mean Please check the document thoroughly.

Yes. Russian word order is fairly flexible.

The basic sentence is:

Проверьте документ хорошенько.

But you could also say:

• Хорошенько проверьте документ.
• Документ хорошенько проверьте.

The meaning stays close, but the focus changes.

For example:

• Хорошенько проверьте документ puts extra emphasis on thoroughly
• Документ хорошенько проверьте puts more emphasis on the document

The original order sounds natural and neutral.

You would usually say:

Проверь документ хорошенько.

That is the singular informal imperative.

So:

• Проверь = check! — to one friend / child / someone you address with ты
• Проверьте = check! — to several people, or politely to one person

Хорошенько is natural and common, but it has a slightly colloquial or conversational feel.

In more formal or professional language, people might prefer words like:

• тщательно = thoroughly
• внимательно = carefully

For example:

• Проверьте документ тщательно.
• Проверьте документ внимательно.

But Проверьте документ хорошенько is still perfectly natural, especially in everyday speech.

Russian has no articles, so there is no direct equivalent of a or the.

So документ can mean:

• a document
• the document

The exact meaning depends on context.

In this sentence, if the listener already knows which document is meant, English would usually translate it as the document. But Russian does not need a separate word for that.

Yes, it can.

Because of хорошенько, the speaker is not just saying check it but make sure you check it properly. Depending on tone, it can sound like:

• careful advice
• a firm instruction
• mild warning not to be careless

So the sentence can feel a bit more forceful than a plain Проверьте документ.

Tone of voice matters a lot here. In a friendly tone, it sounds helpful. In a strict tone, it sounds more like an order.
