Samochód stoi teraz w warsztacie, a my wracamy do domu autobusem.

In Polish, stać is commonly used for things that are in an upright, stationary position, including vehicles.

So:

• Samochód stoi w warsztacie = The car is in the garage/workshop
• more literally: The car is standing in the workshop

This is very natural in Polish. You would not normally use być here unless you just want to say that something exists or is somewhere in a more neutral way. With objects like cars, bottles, chairs, etc., Polish often prefers verbs like:

• stać = stand
• leżeć = lie
• wisieć = hang

Warsztat usually means a workshop or repair shop. In this sentence, w warsztacie most naturally means at the garage / in the repair shop, especially because the subject is a car.

So:

• Samochód stoi teraz w warsztacie = The car is at the repair shop now

Depending on context, warsztat can also mean a workshop in a more general sense, but with samochód, the repair-shop meaning is the obvious one.

After the preposition w meaning in, Polish normally uses the locative case.

• dictionary form: warsztat
• locative singular: warsztacie

So:

• w warsztacie = in the workshop / at the garage

This is a very common pattern:

• w domu = in the house / at home
• w sklepie = in the shop
• w samochodzie = in the car

Both a and i can be translated as and, but they are not used in exactly the same way.

Here:

• Samochód stoi teraz w warsztacie, a my wracamy do domu autobusem.

The conjunction a often links two contrasting or parallel ideas:

• the car is in the shop
• and meanwhile / whereas we are going home by bus

So a works well because it sets up a contrast between the car’s situation and our situation.

By contrast, i is a more straightforward and used for simple addition.

A rough feeling is:

• i = and
• a = and / while / whereas / and in contrast

Wracamy is the 1st person plural present tense form of wracać.

• wracać = to return, to be returning
• wracamy = we are returning / we return / we’re coming back

Polish present tense often covers both the simple present and the English present continuous, depending on context.

So wracamy can mean:

• we are going back
• we’re returning
• we come back (less likely in this exact sentence)

Here, because of teraz and the context, it clearly means we are returning now.

The preposition do takes the genitive case.

• dictionary form: dom
• genitive singular: domu

So:

• do domu = to home / to the house

In English we say go home, but Polish uses do domu.

Compare:

• idę do domu = I’m going home
• wracamy do domu = we’re returning home
• jadę do szkoły = I’m going to school

Autobusem is the instrumental singular of autobus.

It is used because in Polish, the means of transport is often expressed with the instrumental case, without a preposition.

• autobus = bus
• autobusem = by bus

So:

• wracamy do domu autobusem = we’re going home by bus

Other examples:

• jadę pociągiem = I’m going by train
• lecimy samolotem = we’re going by plane
• idę pieszo = I’m going on foot

Polish word order is fairly flexible, but different orders change the emphasis.

The sentence as given:

• Samochód stoi teraz w warsztacie, a my wracamy do domu autobusem.

sounds natural and neutral.

You could move teraz, but that would change the focus slightly:

• Samochód teraz stoi w warsztacie... = emphasis on now
• A my teraz wracamy do domu autobusem = emphasis that we are now returning

So yes, Polish allows movement, but the original order is very natural.

Polish does not have articles like a/an and the.

That means:

• samochód can mean a car or the car
• dom can mean a house/home or the house/home

The exact meaning comes from context.

In this sentence, samochód is understood as the car, because the situation clearly refers to a specific car. Likewise, do domu is naturally understood as home.

It can mean both, depending on context.

• dom = house
• do domu very often = home

So:

• wracamy do domu = we’re going home

This is one of those places where Polish uses the noun dom, but English prefers home rather than to the house.

Yes, Polish often omits subject pronouns because the verb ending already shows who is doing the action.

• wracamy already means we return / we are returning

So you could say:

• Samochód stoi teraz w warsztacie, a wracamy do domu autobusem.

However, my is included here for emphasis or contrast:

• the car is in the shop, and we are going home by bus

That makes sense because the sentence contrasts the car with the people.

Usually yes, but its use can be a little broader depending on context.

In this sentence:

• teraz = now

So:

• Samochód stoi teraz w warsztacie = The car is at the repair shop now

It marks the current situation. In other contexts, teraz can also mean something like at this point or these days, depending on what is being discussed.

It breaks down like this:

• wracamy = we are returning
• do domu = home / to the house
• autobusem = by bus

So the pattern is:

verb + destination + means of transport

This is a very useful pattern in Polish:

• Idziemy do szkoły pieszo. = We’re going to school on foot.
• Jedziecie do pracy tramwajem. = You’re going to work by tram.
• Wracam do domu taksówką. = I’m going home by taxi.

Yes. In Polish, the most natural way to say by bus is simply the instrumental form:

• autobusem

You generally do not need a separate word corresponding directly to English by.

So these are natural:

• jadę autobusem = I’m going by bus
• wracamy autobusem = we’re coming back by bus

That is standard Polish usage.
