Tento osobní doklad je důležitý.

Tento means this.

A common learner question is why Czech uses tento instead of just ten. In modern Czech:

• tento = this
• tamten = that over there
• ten can sometimes mean the, that, or even this depending on context

So in a clear textbook sentence, tento is often used because it unambiguously means this.

In this sentence, tento osobní doklad = this personal document / this ID document.

Because all three words are in the nominative singular masculine form.

Here is the agreement:

• tento = demonstrative pronoun, masculine singular nominative
• osobní = adjective, masculine singular nominative
• doklad = noun, masculine singular nominative

Czech words have to agree in gender, number, and case. Since doklad is the main noun and it is masculine singular nominative, the words describing it must match.

Doklad is masculine inanimate.

You can often tell it is masculine because its basic form ends in a consonant. It is specifically inanimate, not animate, because it refers to an object, not a person or animal.

That matters because Czech adjectives, pronouns, and some verb forms change differently depending on whether a masculine noun is animate or inanimate.

Doklad is a general word meaning something like:

• document
• proof
• certificate
• ID document

In this sentence, osobní doklad usually means a personal identification document, such as:

• a passport
• an ID card
• another official identity document

So while doklad by itself is broad, osobní doklad is a more specific phrase.

Yes. Osobní literally means personal.

But as in English, the exact meaning depends on context. In osobní doklad, it does not mean something emotional or private; it means a document connected with a person’s identity.

So osobní doklad is best understood as personal ID document or identity document.

In a normal Czech sentence like this, je is required.

• je = is

So:

• Tento osobní doklad je důležitý.
• literally: This personal document is important.

Unlike some Slavic languages, standard Czech normally does use the present tense of být (to be) in this kind of sentence.

You might see omission only in special styles, such as headlines, notes, or very informal fragments, but not in a normal full sentence.

Because it agrees with doklad, which is:

• masculine
• singular
• nominative

The adjective důležitý means important, and its ending changes depending on what it describes.

Here it describes doklad, so it takes the masculine singular nominative form:

• masculine singular: důležitý
• feminine singular: důležitá
• neuter singular: důležité

So if the noun changed, the adjective form would change too.

It is an adjective.

In this sentence, it functions as a predicate adjective, meaning it comes after je and describes the subject:

• Tento osobní doklad = subject
• je důležitý = is important

This is similar to English: The document is important.

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

So Czech simply says:

• Tento osobní doklad je důležitý.

English has to decide between things like:

• This personal document is important
• The personal document is important
• A personal document is important

Czech usually expresses that kind of meaning through:

• context
• word order
• demonstratives like ten or tento

Here, tento already makes the phrase definite: this document.

Yes, Czech word order is more flexible than English, but changing it can shift the emphasis.

The neutral order here is:

• Tento osobní doklad je důležitý.

Other possible orders include:

• Osobní doklad je důležitý. = The personal document is important / A personal document is important
• Důležitý je tento osobní doklad. = emphasis on this personal document
• Tento doklad je osobní a důležitý. = different meaning: This document is personal and important

So yes, word order can change, but you should learn the neutral order first.

Yes, you can.

Without tento, the sentence means:

• A personal document is important
• The personal document is important
• Personal ID is important

The exact English translation depends on context.

Adding tento makes it more specific:

• Tento osobní doklad je důležitý. = This personal document is important.

So tento narrows it down to one specific document.

A rough pronunciation guide is:

• dů-le-ži-tý

A few useful points:

• Czech stress is usually on the first syllable: DŮležitý
• ů is pronounced like a long oo
• ž sounds like the s in measure
• ý is a long ee sound

So it sounds roughly like DOO-leh-zhi-tee, with the stress at the beginning.

Yes, it is a common expression.

It usually refers to an official document identifying a person. Depending on context, it may include:

• občanský průkaz = ID card
• pas = passport
• other identity papers

So learners should understand osobní doklad as a normal everyday phrase, not just a random combination of personal + document.

The adjective and demonstrative would change to match the noun.

For example:

• Tato karta je důležitá. = This card is important.

  • karta is feminine
  • so you get tato and důležitá

• Toto potvrzení je důležité. = This confirmation is important.

  • potvrzení is neuter
  • so you get toto and důležité

That is one of the key grammar patterns in Czech: words that belong together must agree.

The dictionary forms are:

• tento = this
• osobní = personal
• doklad = document / proof / ID document
• být → je = to be → is
• důležitý = important

This is useful because in Czech, many words change form, so learners need to know the base form to look them up.
