Trvalý pobyt se zaeviduje v informačním systému evidence obyvatel.

Trvalý pobyt is an official administrative term. It means a person’s permanent residence or registered permanent address in the legal/bureaucratic sense.

It does not always mean the place where someone is physically living every day. In Czech administration, a person can have a trvalý pobyt at one address while actually staying somewhere else.

• trvalý = permanent
• pobyt = stay, residence

So together it means something like permanent residence status/address.

Because zaeviduje is a perfective verb form.

In Czech, perfective verbs do not normally express a true present action. Their “present-tense” forms usually refer to the future, especially a completed future event.

So:

• eviduje = he/she/it is registering, registers, is recording (imperfective)
• zaeviduje = he/she/it will register, will record officially (perfective)

Here, zaeviduje means that the registration will be completed.

They are an aspect pair:

• evidovat = imperfective, focusing on the process or repeated action of recording/registering
• zaevidovat = perfective, focusing on the completion of entering something into the records

The prefix za- often helps create a perfective verb and can give the sense of getting something entered/recorded officially.

In bureaucratic language, zaevidovat is very common for things like applications, addresses, residence, documents, and official entries.

Here se helps form a reflexive passive.

So instead of saying who performs the action, Czech uses se to make the sentence more impersonal:

• Trvalý pobyt se zaeviduje... = Permanent residence will be registered...

This is very common in official and administrative Czech.

It does not mean that the residence is doing something to itself. It is just a grammatical way to make the sentence passive or impersonal.

Yes. It is a kind of passive, specifically the reflexive passive.

Czech has two common ways to express passive meaning:

1. Reflexive passive

   • Trvalý pobyt se zaeviduje.

2. Periphrastic passive with být

   • passive participle
   • Trvalý pobyt bude zaevidován.

Both mean roughly the same thing: Permanent residence will be registered.

The version with se is very natural in official instructions and regulations.

Trvalý pobyt is in the nominative singular.

Even though the sentence is passive in meaning, trvalý pobyt is still the grammatical subject, so it stays in the nominative:

• trvalý = masculine singular nominative adjective
• pobyt = masculine singular nominative noun

The verb zaeviduje is also singular because it agrees with trvalý pobyt.

Because the preposition v here means in, and when it expresses location, it requires the locative case.

So:

• informační systém = information system
• v informačním systému = in the information system

Both words change:

• informační → informačním
• systém → systému

This is standard adjective-noun agreement in the locative singular.

This is a genitive phrase meaning of inhabitants / of residents.

• evidence = record, registry, registration records
• obyvatel = inhabitants/residents

So:

• evidence obyvatel = records/register of inhabitants

More precisely:

• evidence is in the genitive singular after systému
• obyvatel is in the genitive plural, depending on evidence

So the whole chain is:

• v informačním systému evidence obyvatel
• literally: in the information system of the register/records of inhabitants

A useful point: the noun evidence has the same form in nominative singular and genitive singular, so it looks unchanged here.

Because Czech does not have articles like English the and a/an.

Whether something is definite or indefinite is usually understood from:

• context
• word order
• the situation
• sometimes demonstratives like ten, if needed

So Trvalý pobyt se zaeviduje... can naturally mean The permanent residence will be registered... or Permanent residence will be registered..., depending on context.

Yes. Czech word order is flexible, and changing it can shift emphasis.

For example, these are possible:

• Trvalý pobyt se zaeviduje v informačním systému evidence obyvatel.
• V informačním systému evidence obyvatel se zaeviduje trvalý pobyt.

The original version starts with trvalý pobyt, so that is the topic or focus at the beginning. This is common in formal written Czech.

The basic meaning stays the same, but the information structure changes slightly.

It is quite formal and administrative.

Several things make it sound official:

• trvalý pobyt is a legal/administrative term
• zaeviduje is typical bureaucratic wording
• informační systém evidence obyvatel is institutional language

In everyday speech, people would often use simpler wording, but in forms, regulations, office instructions, and legal texts, this sentence sounds completely normal.
