Взгляните на документ.

Взгляните is the imperative form of the verb взглянуть, which means to glance, to look, or to take a look.

Here it means something like:

• Take a look at the document.
• Please look at the document.

The ending -те shows that it is either:

• addressed to more than one person, or
• a polite singular form, like Russian you used respectfully.

In Russian imperatives, -те is added to make the command:

• plural: spoken to several people
• polite: spoken to one person formally

So:

• взгляни = look / take a look (informal singular)
• взгляните = look / take a look (polite singular or plural)

This is very common in Russian:

• скажи → скажите
• посмотри → посмотрите
• взгляни → взгляните

The verb взглянуть normally uses the preposition на when you say what someone is looking at.

So Russian says:

• взглянуть на что-то = to glance at something

That is why you get:

• на документ = at the document

This is just part of the verb’s normal pattern. English learners often want to translate word-for-word, but here you should learn the whole structure:

• взглянуть на + object

After на with взглянуть, the noun goes in the accusative case.

The noun документ is masculine and inanimate. For masculine inanimate nouns, the accusative singular is usually the same as the nominative singular.

So:

• nominative: документ
• accusative: документ

That is why the form does not change here.

If it were a different noun, you might see a clearer change. For example:

• Взгляните на книгу. = Look at the book.
• Взгляните на письмо. = Look at the letter.

Both can often be translated as look or take a look, but they are not exactly the same.

• взгляните suggests a quick glance or a brief look
• посмотрите is more general and often means look or watch

So:

• Взгляните на документ. = Take a quick look at the document.
• Посмотрите на документ. = Look at the document.

In many everyday situations, they can overlap, but взгляните often sounds a bit more like just have a look for a moment.

Yes. Взглянуть is a perfective verb.

That matters because perfective verbs often express a single complete action. Here, the idea is:

• take one look
• have a quick glance

The imperfective partner is взглядывать, but that is much less common in basic everyday commands.

So взгляните naturally fits a request for one completed action: please take a look.

Yes, it sounds at least somewhat formal or polite because of взгляните.

It could be used:

• in an office
• by a teacher
• by a doctor
• in customer service
• in writing or announcements

Compared with Посмотри на документ, it sounds more polite and less casual.

Also, взглянуть itself can sound a little more polished than very basic посмотреть in some contexts.

The stress is:

• взгляни́те
• на
• докуме́нт

So you pronounce it roughly as:

• vzglya-NEE-tye na daku-MENT

The stressed syllables are important in Russian, because vowel pronunciation changes when unstressed.

Yes, it is a bit tricky because of the consonant cluster at the beginning.

A rough English-style approximation is:

vzglya-NEE-tye

Break it down like this:

• вз = vz
• гля = roughly glya
• ни = nee
• те = tye

A more careful pronunciation is close to:

[vz-glya-NEE-tye]

The beginning взгл- is hard for English speakers, so it helps to practice slowly:

1. вз
2. взг
3. взгля
4. взгляни
5. взгляните

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

The neutral version is:

• Взгляните на документ.

But you might also hear:

• На документ взгляните.

That version puts more emphasis on the document.

Even so, for learners, the standard neutral order is the best one to use first:

• Взгляните на документ.

Yes, but it depends on the situation.

It sounds natural in contexts like:

• Please take a look at this document
• Have a quick look at the document
• Kindly review this paper for a moment

In very casual speech, many people might more often say:

• Посмотрите на документ.
• Посмотри на документ.

So Взгляните на документ is natural, but slightly more polished or deliberate than the most basic everyday option.
