Moje sestra si dnes také bere bundu, protože ráno prší.

Moje sestra means my sister.

It is in the nominative case, because it is the subject of the sentence — the person doing the action.

• moje = my
• sestra = sister

Czech often changes word endings depending on grammatical case, but here sestra stays in its basic dictionary form because it is the subject.

Si is a short reflexive/dative pronoun. In this sentence, it does not mean herself in a strong English sense, but it shows that the action is being done for oneself or to oneself.

So:

• bere bundu = takes a jacket
• bere si bundu = takes/puts on a jacket for herself

With clothing, Czech very often uses si in this kind of sentence. It sounds natural because the person is putting on or taking the item for their own use.

These verbs mean different things:

• bere si bundu = she is taking / putting on a jacket
• nosí bundu = she wears a jacket, often in a general or habitual sense

So in this sentence, the idea is about today, in this particular situation, she is taking a jacket because it is raining in the morning.

If you said nosí bundu, it could sound more like a general habit or style choice.

Both are related to the idea of taking, but they are different aspects:

• bere = imperfective, ongoing or general action
• vezme = perfective, one completed action

Here, bere si bundu sounds natural because it describes what she is doing in the situation. It is a present-tense description of an action in progress or a normal present-time event.

Compare:

• Moje sestra si bere bundu. = My sister is taking/putting on a jacket.
• Moje sestra si vezme bundu. = My sister will take/put on a jacket.
  (Perfective present usually has future meaning in Czech.)

Because bunda is the direct object of the verb bere si.

The noun bunda is feminine, and in the accusative singular its form changes:

• nominative: bunda
• accusative: bundu

So:

• bunda = jacket
• bere si bundu = takes/puts on a jacket

This is a very common feminine pattern in Czech.

Také means also / too.

In this sentence, it tells us that my sister too is taking a jacket.

Czech word order is flexible, so také can move depending on emphasis, but its position affects what sounds most natural or what gets stressed.

Here:

• Moje sestra si dnes také bere bundu...
  = My sister is also taking a jacket today...

You may also hear other placements, but not all of them sound equally natural in every context. Czech often places words like také near the part they relate to.

Yes, Czech word order is much more flexible than English word order.

Dnes means today, and here it appears before také bere bundu. That is a natural placement, but other orders are possible depending on emphasis.

For example:

• Moje sestra si dnes také bere bundu.
• Dnes si moje sestra také bere bundu.
• Moje sestra si také dnes bere bundu.

These all mean roughly the same thing, but the focus changes slightly.

English relies heavily on word order for grammar. Czech uses case endings, so word order is often used more for emphasis, information structure, and style.

Protože means because.

It introduces a subordinate clause:

• protože ráno prší = because it is raining in the morning

Unlike in German, Czech does not send the verb to the end of the clause after protože. The verb stays in a normal position:

• protože ráno prší

not something like protože ráno ... prší with a special end position rule.

So this part is often easier for English speakers than some other European languages.

Because ráno here is being used as an adverb, meaning in the morning / this morning / in the morning time.

So:

• ráno prší = it is raining in the morning

You do not need a preposition here.

Compare:

• Ráno prší. = It rains / it is raining in the morning.
• V jednom ránu... would be a different structure, and generally not what you want here.

For everyday time expressions, Czech often uses simple adverbs:

• dnes = today
• zítra = tomorrow
• ráno = in the morning
• večer = in the evening

Prší means it is raining or it rains.

Literally, Czech uses a verb without an expressed subject here. English uses it, but that it does not refer to a real thing — it is just a grammatical subject.

Czech does not need that dummy subject, so it simply says:

• prší = is raining

This is very common with weather expressions in Czech.

Yes. Prší is present tense, and Czech present tense can cover both ideas depending on context:

• it rains
• it is raining

In this sentence, because of dnes and ráno, the natural meaning is more like it is raining this morning or it rains in the morning today.

Context usually tells you whether the meaning is general, habitual, or happening now.

Yes, depending on context.

With clothing, brát si can often mean something like:

• take
• take along
• put on

In this sentence, since the reason is because it is raining in the morning, the intended sense is probably:

• she is taking a jacket
• or putting on a jacket

English chooses different verbs more strictly, but Czech can be a bit broader here.

Czech has no articles, so there is no direct equivalent of English a or the.

So bundu can mean:

• a jacket
• the jacket

The exact meaning comes from context.

In this sentence, English will usually translate it as a jacket, because that sounds most natural unless a specific jacket has already been mentioned.

A rough guide:

• sestra ≈ SEH-stra
• také ≈ ta-KAY
• protože ≈ PRO-to-zhe
• prší ≈ PRR-shee

A few important points:

• é is a long vowel.
• ž sounds like the s in measure.
• š sounds like sh.
• ř does not appear in this sentence, but learners often look for it because Czech is famous for it.
• In prší, the r is pronounced clearly; Czech allows consonant-heavy combinations that may feel unusual to English speakers.

Yes. Depending on context, natural translations could include:

• My sister is also taking a jacket today because it’s raining this morning.
• My sister is also putting on a jacket today because it’s raining this morning.
• My sister is taking a jacket today too, because it’s raining this morning.

The exact English wording depends on whether you want to emphasize:

• also / too
• taking vs putting on
• this morning vs in the morning

Czech leaves some of that to context more than English does.
