Až porada skončí, půjdu do banky.

Here až means when, once, or after in a future-time sense:

• Až porada skončí = When/Once the meeting ends

It does not mean until in this sentence, even though až can sometimes be translated that way in other contexts. Here it introduces the event that must happen first.

This is a very common point for English speakers.

Skončí is formally a present-tense form, but the verb skončit is perfective. In Czech, the present tense of a perfective verb usually refers to the future.

So:

• porada skončí = the meeting will end

After words like až referring to a future event, Czech normally uses this structure instead of a separate future auxiliary.

Because skončit is perfective, and it focuses on the meeting reaching its endpoint.

• skončit = to finish / to end completely
• končit = to be ending / to end in an imperfective, ongoing, repeated, or more general sense

In this sentence, the important idea is that the meeting must be finished first, and only then will the speaker go to the bank. That is why skončí fits better.

The verb jít (to go on foot / to go) has an irregular future:

• já půjdu = I will go
• ty půjdeš
• on/ona půjde
• etc.

So budu jít is not the normal way to form the future of jít.

In this sentence:

• půjdu do banky = I will go to the bank

Because Czech uses do + genitive to express movement into or to certain places.

Here the speaker is going to the bank, so:

• do banky

The noun banka changes to the genitive singular:

• banka → banky

So:

• jdu do banky = I’m going to the bank
• půjdu do banky = I’ll go to the bank

Because the preposition do requires the genitive case, not the accusative.

• nominative: banka
• genitive: banky
• accusative: banku

So after do, you must say:

• do banky

not do banku.

Because porada is the subject of the clause Až porada skončí.

The subject is in the nominative case, so it stays:

• porada = meeting

Here:

• porada = the thing that will end
• skončí agrees with it in the 3rd person singular

Yes. Czech often leaves out subject pronouns when they are clear from the verb form.

• půjdu already means I will go

So:

• (já) půjdu do banky

The já is optional and usually omitted unless you want emphasis or contrast.

Yes, absolutely.

Both are natural:

• Až porada skončí, půjdu do banky.
• Půjdu do banky, až porada skončí.

The meaning stays basically the same. The difference is mainly one of emphasis and flow:

• starting with Až porada skončí emphasizes the condition/time first
• starting with Půjdu do banky emphasizes the main action first

Yes. In Czech, a subordinate clause introduced by až is separated by a comma.

So you write:

• Až porada skončí, půjdu do banky.

And also:

• Půjdu do banky, až porada skončí.

No. Až can have different meanings depending on context.

In this sentence, it means something like:

• when
• once
• after

But in other contexts it can be closer to:

• until
• as late as
• only

So learners should not memorize just one English equivalent. Here, the best understanding is: once the meeting is over.

Yes, but až is usually the more natural choice when talking about a future event that will happen first.

• Až porada skončí... strongly points to a future moment: once the meeting ends
• Když porada skončí... is possible, but když often feels more general and is very commonly used for when/if in broader contexts

So in this sentence, až is a very good, idiomatic choice.

Literally, jít is the basic verb for to go, historically associated with going on foot. In many everyday sentences, though, English simply translates it as go.

So:

• půjdu do banky = I’ll go to the bank

In normal conversation, this is the natural Czech wording unless you specifically want to emphasize a different means of transport.

Roughly:

• půjdu ≈ POY-doo

A few helpful notes:

• ůj sounds like a diphthong similar to oy in boy
• stress in Czech is normally on the first syllable
• so the stress is on půj-

Likewise:

• porada = PO-ra-da
• skončí = SKON-chee
• banky = BAN-kee

It has two parts:

1. Až porada skončí
   = a subordinate time clause
   = When/Once the meeting ends

2. půjdu do banky
   = the main clause
   = I’ll go to the bank

So the full structure is:

• [When X happens], [I will do Y].

This is a very common Czech pattern for talking about future sequence.
