Dokud nebudou všechny police na stěně, nechci vybalit další knihy.

Dokud means until in this sentence.

So:

• Dokud nebudou všechny police na stěně... = Until all the shelves are on the wall...

A useful thing to notice is that Czech often uses dokud with a negative verb where English uses a positive idea:

• Dokud nebudou... = Until they are... / Until they have been put up...

This pattern is very common in Czech.

Because Czech normally uses negation after dokud when talking about something that has not happened yet.

So Czech says:

• Dokud nebudou všechny police na stěně... literally: Until all the shelves will not be on the wall...

But in natural English, we translate it as:

• Until all the shelves are on the wall...

This is one of those places where Czech and English structure the idea differently.

Nebudou is the 3rd person plural future of být (to be), in the negative.

Breakdown:

• budou = they will be
• nebudou = they will not be

It is plural because the subject is všechny police = all the shelves.

In Czech, police can mean shelf or shelves, depending on context.

Here:

• police = shelves

This is a false friend for English speakers, because it looks exactly like English police, but it has nothing to do with law enforcement here.

Forms to notice:

• police can be singular in some contexts
• police can also be plural

In this sentence, všechny police clearly shows it is plural, because všechny means all (feminine plural).

Because police is a feminine noun, and here it is in the nominative plural as the subject of the clause.

So:

• všechny = all for feminine plural
• police = shelves

Together:

• všechny police = all the shelves

The verb matches this plural subject:

• všechny police nebudou

Na stěně means on the wall.

Breakdown:

• na = on
• stěna = wall
• stěně = wall in the locative singular

After na with the meaning of location (on somewhere), Czech uses the locative:

• na stole = on the table
• na zdi / na stěně = on the wall

So na stěně is a location phrase.

Because the preposition na takes the locative case when it describes location.

Here the meaning is not motion onto the wall, but location on the wall.

So:

• stěna = base form
• na stěně = on the wall

Compare the idea:

• location: na stěně = on the wall
• motion onto something can use a different case pattern in other contexts

For this sentence, just remember that na + locative often means on / at a place.

Because vybalit is perfective, and it focuses on the action as a completed whole: to unpack / to unpack completely.

So:

• nechci vybalit další knihy = I don’t want to unpack any more books / the next batch of books

If you used vybalovat instead, it would sound more like the ongoing activity:

• nechci vybalovat další knihy = I don’t want to be unpacking more books

In this sentence, the speaker is talking about whether to do the action at all before the shelves are up, so the perfective vybalit fits well.

Další knihy means more books, additional books, or the next books depending on context.

Here the most natural translation is:

• I don’t want to unpack any more books.

Breakdown:

• další = next / additional / more
• knihy = books

So the speaker has probably already unpacked some books and does not want to continue until the shelves are installed.

Because vybalit takes a direct object, and here the object is in the accusative plural.

For feminine nouns like kniha:

• nominative singular: kniha
• accusative singular: knihu
• nominative plural: knihy
• accusative plural: knihy

So in this sentence:

• vybalit další knihy = to unpack more books

The form knih would be used in other grammatical contexts, not here.

Literally, it means:

• I don’t want to unpack

But in context, it can sound close to:

• I’m not willing to unpack
• I don’t want to go ahead and unpack
• I won’t unpack any more books until...

So the literal meaning is about wanting, but the practical meaning can be a refusal or decision.

Yes. A natural English translation would be something like:

• Until all the shelves are up on the wall, I don’t want to unpack any more books.
• I don’t want to unpack any more books until all the shelves are on the wall.

The first version keeps the Czech order more closely. The second sounds especially natural in English.

Czech word order is flexible, and it is often used to organize information rather than strictly mark grammar.

This sentence begins with the time condition:

• Dokud nebudou všechny police na stěně...
• Until all the shelves are on the wall...

Then it gives the main statement:

• nechci vybalit další knihy
• I don’t want to unpack more books

Starting with dokud... puts strong emphasis on the condition first. English can do this too:

• Until all the shelves are on the wall, I don’t want to unpack any more books.

In normal context, police na stěně strongly suggests the shelves are installed/mounted on the wall, not just near it.

So the sentence most likely means:

• the shelves have not been put up yet
• the speaker does not want to unpack more books before that is done

If someone wanted to say the shelves were merely against the wall, they would probably choose a different expression.
