Oprava začne zítra.

Oprava is a noun, and it is feminine.

It most often means repair, fix, or sometimes correction, depending on context. In this sentence, it means repair.

You can see it is feminine because it follows a common feminine noun pattern ending in -a:

• ta oprava = the repair

That gender matters because adjectives, pronouns, and sometimes past-tense verbs will agree with it.

Czech has no articles, so it does not use words like the or a/an.

So:

• oprava can mean a repair or the repair

Which one is meant depends on context. In a sentence like this, English often uses the repair because both speaker and listener usually know which repair is being talked about.

Začít is the infinitive, meaning to begin / to start.

In the sentence, you need a finite verb that matches the subject, so Czech uses:

• začne = it/he/she will begin

Here it matches the subject oprava:

• Oprava začne = The repair will begin

So:

• začít = to begin
• začne = will begin / begins

This is because začít is a perfective verb.

In Czech, perfective verbs often use present-tense endings to express future meaning.

So:

• začne literally looks like a present form
• but with a perfective verb, it means will begin

Compare:

• začíná = is beginning / begins (imperfective)
• začne = will begin (perfective)

That is a very important Czech pattern.

Because the sentence talks about a single completed start in the future: the repair will start tomorrow.

Czech prefers the perfective verb začít for that idea:

• Oprava začne zítra. = The repair will start tomorrow.

If you used začíná, it would sound more like:

• a scheduled or ongoing process,
• or a more descriptive present-time framing.

So for a straightforward future event, začne is the most natural choice.

Because Czech usually does not need subject pronouns when the verb form already shows the person and number.

Here the subject is explicitly stated as oprava, so adding ona would be unnecessary:

• Oprava začne zítra. = natural
• Ona oprava začne zítra. = not normal in this context

Czech uses pronouns like on / ona / ono mostly for emphasis, contrast, or when the subject is otherwise unclear.

The ending -e marks the 3rd person singular form of začít.

That means it is used with:

• he
• she
• it
• or any singular noun

So:

• oprava začne = the repair will begin

Other related forms are:

• začnu = I will begin
• začneš = you will begin
• začneme = we will begin
• začnete = you (plural/formal) will begin
• začnou = they will begin

Zítra means tomorrow, and in this sentence it functions as an adverb of time.

It tells you when the action happens:

• Oprava začne zítra. = The repair will begin tomorrow.

Learners often look for a case ending here, but zítra is best treated as a fixed time expression/adverb in modern usage.

Yes. Czech word order is fairly flexible, and changing it often changes focus or emphasis, not the basic meaning.

For example:

• Oprava začne zítra. = neutral; the repair will start tomorrow
• Zítra začne oprava. = emphasizes tomorrow
• Začne zítra oprava. = possible, but less neutral and more context-dependent

The most natural neutral version is the original:

• Oprava začne zítra.

A rough pronunciation guide is:

• Oprava ≈ OH-pra-va
• začne ≈ ZACH-neh
  (the č sounds like ch in church)
• zítra ≈ ZEE-tra

A few details:

• á and í are long vowels
• č = ch as in church
• ř does not appear in this sentence, so pronunciation is relatively friendly for beginners

Yes. Oprava can mean different kinds of fixing/correcting, depending on context.

Common possibilities include:

• repair of a road, machine, building, etc.
• correction of mistakes
• make-up exam / resit in some school contexts

So the exact meaning comes from context. In this sentence, if the meaning shown to the learner is repair, then that is the intended reading.
