Pošlete přílohu a elektronické podání datovou schránkou.

Pošlete is the verb poslat (to send) in the 2nd person plural imperative.

So it means:

• send! when speaking to more than one person
• send! when addressing one person formally (like you in a formal instruction)

That is very common in official Czech instructions.

A useful thing to know: pošlete can also be future tense (you will send) in other contexts. But in a sentence like this, especially as an instruction, it is naturally understood as an imperative: Send ...

Because přílohu is the accusative singular of příloha (attachment, enclosure).

Here, přílohu is the direct object of pošlete — it is the thing being sent.

• nominative: příloha
• accusative: přílohu

So Czech changes the ending because the noun’s grammatical role changes.

Because elektronické has to agree with podání.

The noun podání is:

• neuter
• singular
• here also accusative, but for this noun the accusative singular looks the same as the nominative singular

So the adjective must match that:

• elektronické podání

This is a normal adjective + noun agreement pattern in Czech.

Podání is a noun from the verb podat (to submit, to file).

In administrative or legal Czech, podání often means:

• a submission
• a filing
• an application/document submitted to an office

So elektronické podání is not just any “electronic sending.” It usually refers to an official electronic submission in an administrative context.

Because datovou schránkou is in the instrumental case, which here expresses the means or method: by means of a data box / via a data box.

Base form:

• datová schránka

Instrumental singular:

• datovou schránkou

So the sentence is using the instrumental to mean something like:

• send it using a data box
• send it via a data box

This use of the instrumental without a preposition is common when Czech expresses the tool, means, or method.

A datová schránka is a specific Czech electronic communication system used for official correspondence with government offices, courts, and sometimes businesses.

It is often translated loosely as:

• data box
• data mailbox

But it is not just an ordinary email inbox. It is a formal, state-recognized system for official electronic delivery.

So in this sentence, datovou schránkou refers to sending the documents through that official system.

Yes. A means and.

It links two objects of the verb pošlete:

• přílohu
• elektronické podání

So the instruction is to send both of them.

Structurally:

• Pošlete = send
• přílohu a elektronické podání = the attachment and the electronic submission
• datovou schránkou = via data box

Because Czech does not have articles.

English needs words like:

• a
• an
• the

Czech usually expresses that meaning through context instead.

So přílohu can mean:

• an attachment
• the attachment

and elektronické podání can mean:

• an electronic submission
• the electronic submission

The exact meaning depends on the situation, not on an article.

No, Czech word order is fairly flexible.

Pošlete přílohu a elektronické podání datovou schránkou. is a natural instruction, but other orders are also possible, for example:

• Přílohu a elektronické podání pošlete datovou schránkou.

That version puts more focus on what should be sent.

Even though Czech word order can move around, the cases still show the grammatical roles:

• přílohu = object
• podání = object
• datovou schránkou = means/method

So the meaning stays clear.

Yes. In real usage, you may also see:

• prostřednictvím datové schránky = through / by means of a data box
• sometimes přes datovou schránku in less formal wording

But datovou schránkou by itself is a compact and perfectly normal way to express the method.

So this sentence uses a very typical Czech structure:

• verb + object + instrumental of means

Yes, it sounds formal and administrative.

Clues include:

• the imperative pošlete in a formal/plural form
• the phrase elektronické podání
• the term datová schránka, which belongs to official communication

So this is the kind of sentence you might see in:

• instructions from an office
• a government website
• an administrative form or notice
