Proszę podłączyć kabel do gniazdka i sprawdzić, czy żarówka świeci.

Proszę here makes the instruction polite. In this kind of sentence, proszę + infinitive means something like please do... or please ....

So:

• Proszę podłączyć... = Please connect...
• Proszę sprawdzić... = Please check...

This is very common in instructions, customer service, manuals, and formal spoken Polish.

Because they depend on proszę in this polite instruction pattern:

• proszę + infinitive

So Polish uses:

• Proszę podłączyć kabel
• Proszę sprawdzić

rather than a direct imperative form.

This sounds more polite and less abrupt than using commands like podłącz or sprawdź.

Podłączyć is a perfective verb, so it presents the action as a completed whole: connect the cable.

That fits well here because the instruction is about completing a specific action:

1. connect the cable
2. check whether the bulb is on

If you used podłączać, that would be the imperfective form, which is more about process, repetition, or ongoing action. In this sentence, perfective is the natural choice.

Because kabel is the direct object of podłączyć, so it is in the accusative case.

For many inanimate masculine nouns in Polish, the accusative singular looks the same as the nominative singular. So:

• nominative: kabel
• accusative: kabel

That is why there is no visible change here.

The preposition do requires the genitive case.

The base form is:

• gniazdko = socket / outlet

After do, it changes to genitive singular:

• do gniazdka = into / to the socket

So the pattern is:

• do + genitive

In this sentence, gniazdko means an electrical socket or wall outlet.

Literally, gniazdo can mean nest, and gniazdko is a diminutive form, but in everyday modern Polish, gniazdko is the normal word for an electrical socket.

Because czy żarówka świeci is a subordinate clause: whether the bulb is shining/is on.

In Polish, subordinate clauses are normally separated by a comma, so:

• sprawdzić, czy żarówka świeci

This is standard punctuation.

Here czy means whether / if in an indirect yes-no question.

So:

• sprawdzić, czy żarówka świeci = check whether the bulb is on

This is different from using czy at the beginning of a direct yes-no question, for example:

• Czy żarówka świeci? = Is the bulb on?

In Polish, świecić is the normal verb for to shine, to give light, or in context to be on / lit.

So żarówka świeci naturally means:

• the bulb is shining
• the bulb is on
• the bulb is lit

In everyday English, check if the bulb is on sounds most natural, but the Polish verb is still świecić.

Yes, very often you can hear:

• czy żarówka się pali

This also means whether the bulb is on / lit.

In everyday usage, both świeci and się pali are possible.
Świeci focuses more on giving light, while się pali often means is burning / is on. For a light bulb, both can work.

Yes, Polish word order is more flexible than English word order.

This sentence uses a very neutral, natural order:

• Proszę podłączyć kabel do gniazdka i sprawdzić, czy żarówka świeci.

You could rearrange parts slightly, especially for emphasis, but this version is the most straightforward and typical for an instruction.

Yes. I simply joins the two actions:

1. podłączyć kabel do gniazdka
2. sprawdzić, czy żarówka świeci

So it means and.

Yes, it is polite and somewhat formal/neutral.

Using proszę + infinitive is common when:

• giving polite instructions
• talking to customers
• writing service or technical directions
• speaking respectfully to someone you do not know well

A more direct command would be:

• Podłącz kabel do gniazdka i sprawdź...

That is not necessarily rude, but it is more direct.

A few parts that learners often ask about:

• proszę: roughly PRO-sheh
• podłączyć: roughly pod-WON-chitch
• gniazdka: roughly GNYAZT-ka
• żarówka: roughly zha-ROOV-ka
• świeci: roughly SHFYEH-chi

A few notes:

• ż sounds like the s in measure
• ś is a softer sh
• ć is a soft ch
• ą is a nasal vowel; before some consonants it may sound a bit like on/om

These are only rough guides, but they help at first.

Żarówka is in the nominative case because it is the subject of świeci:

• żarówka świeci = the bulb is shining / is on

So here:

• żarówka = subject
• świeci = verb

Yes, but the tone changes.

Without proszę, you would normally say:

• Podłącz kabel do gniazdka i sprawdź, czy żarówka świeci.

That is a direct imperative: Connect the cable... and check...

With proszę, it sounds more polite and less abrupt.
