Biegnę na przystanek, bo autobus odjeżdża za pięć minut.

Biegnę is the 1st person singular present tense of biec and usually means I am running in a specific situation, right now or on this occasion.

• Biegnę na przystanek = I’m running to the bus stop
• Biegam comes from biegać and usually means I run in a habitual or repeated sense, like I run regularly or I go running

So here, because the speaker is reacting to an immediate situation, biegnę is the natural choice.

In Polish, subject pronouns are often omitted because the verb ending already shows who is doing the action.

• biegnę = I run / I am running
• the ending -ę tells you it is I

You could say Ja biegnę na przystanek, but ja is usually added only for emphasis, contrast, or emotion.

Both can be translated as to the bus stop, but they are used a little differently.

• na przystanek is the most natural expression when you mean to the bus stop as a destination/place where transport stops
• do przystanku is less natural here and can sound more like movement up to a place rather than the usual idiomatic choice

In Polish, many locations take fixed prepositions. With przystanek, movement toward it is very commonly expressed with na:

• Idę na przystanek = I’m going to the bus stop
• Biegnę na przystanek = I’m running to the bus stop

Actually, przystanek here is in the accusative case, and for this noun the accusative singular looks the same as the nominative singular.

• nominative: przystanek
• accusative: przystanek

After na meaning movement onto/to/toward, Polish usually uses the accusative.

Compare:

• Idę na przystanek = motion toward the stop → accusative
• Jestem na przystanku = location at the stop → locative

That contrast is very important in Polish.

This is the classic Polish difference between movement and location.

• na + accusative = movement toward a place
  
  • Idę na przystanek = I’m going to the bus stop
• na + locative = being at a place
  
  • Jestem na przystanku = I’m at the bus stop

So in your sentence, the speaker is moving toward the stop, which is why we get na przystanek.

Bo means because. It is very common in everyday spoken and written Polish.

• Biegnę na przystanek, bo autobus odjeżdża za pięć minut. = I’m running to the bus stop because the bus leaves in five minutes.

You can often replace it with ponieważ, which is a bit more formal or bookish:

• Biegnę na przystanek, ponieważ autobus odjeżdża za pięć minut.

Both are correct, but bo sounds more natural in ordinary conversation.

In Polish, clauses introduced by bo are normally separated by a comma.

So:

• Biegnę na przystanek, bo autobus odjeżdża za pięć minut.

This is standard punctuation, just like in many English sentences with because.

Polish often uses the present tense to talk about a scheduled or imminent future event, especially with timetables, transport, and fixed plans.

So:

• autobus odjeżdża za pięć minut literally looks like
• the bus departs in five minutes

But in natural English, this may be translated as:

• the bus leaves in five minutes or
• the bus is leaving in five minutes

This is completely normal in Polish.

Odjeżdża comes from odjeżdżać, which means to leave / depart when talking about vehicles such as buses, trains, or trams.

It is used for transport departing from a stop or station.

Examples:

• Pociąg odjeżdża o szóstej. = The train leaves at six.
• Autobus odjeżdża za chwilę. = The bus is leaving in a moment.

For people leaving on foot, Polish would use a different verb, such as wychodzić or iść depending on context.

In Polish, za + accusative is used to mean in a certain amount of time, referring to a point in the future.

• za pięć minut = in five minutes
• za godzinę = in an hour
• za tydzień = in a week

This is a very common structure and worth memorizing.

After numbers like pięć and above, Polish nouns usually go into the genitive plural.

So:

• pięć minut = five minutes
• sześć godzin = six hours
• dziesięć złotych = ten złoty

That is why you get minut, not minuty.

For comparison:

• jedna minuta = one minute
• dwie / trzy / cztery minuty = two / three / four minutes
• pięć minut = five minutes

Not naturally. In this sentence, biegnę strongly suggests a current, specific action: I’m running to the bus stop.

If you wanted a habitual meaning, you would normally use biegam or another structure, depending on the intended sense:

• Często biegam na przystanek. = I often run to the bus stop.
• Codziennie biegnę na przystanek o tej samej porze. = Every day I run to the bus stop at the same time.

Without that kind of context, biegnę is understood as happening now.

Yes, Polish word order is fairly flexible, though some versions sound more natural or put emphasis in different places.

Neutral version:

• Biegnę na przystanek, bo autobus odjeżdża za pięć minut.

Other possible orders:

• Bo autobus odjeżdża za pięć minut, biegnę na przystanek.
• Na przystanek biegnę, bo autobus odjeżdża za pięć minut.

These are grammatically possible, but the original sentence is the most natural, neutral way to say it.

A rough pronunciation guide is:

• biegnę ≈ BYEG-neng

A few important points:

• bie- sounds roughly like byeh
• g is a normal hard g
• ę is a nasal vowel; before some consonants, it may sound a bit like en/em depending on the sound around it

So in everyday speech, biegnę may sound closer to byeg-ne or byeg-neng than a fully nasalized vowel pronounced in isolation.

Not always. Przystanek means stop, especially a public transport stop.

Depending on context, it can be:

• a bus stop
• a tram stop
• sometimes another transport stop

If you want to be specific, you can say:

• przystanek autobusowy = bus stop
• przystanek tramwajowy = tram stop

In your sentence, because autobus appears right after, przystanek is naturally understood as a bus stop.

Yes: it is a very natural, everyday Polish sentence. It uses several common features of spoken Polish:

• omitted subject pronoun: biegnę, not ja biegnę
• informal, common bo for because
• present tense for near future: autobus odjeżdża
• idiomatic movement phrase: na przystanek
• time expression with za: za pięć minut

So this is exactly the kind of sentence worth learning as a model.
