Nasza córka lubi huśtać się na huśtawce.

Because nasza has to agree with córka in gender, number, and case.

• córka = a feminine singular noun
• so our must also be in the feminine singular form: nasza

Compare:

• nasz syn = our son
• nasza córka = our daughter
• nasze dziecko = our child

So nasza is simply the correct agreeing form of nasz.

Yes. Córka is the standard, neutral everyday word for daughter.

You may also see:

• córa — a less common variant; it can sound more literary, emotional, or regional

For most learners, córka is the safest and most useful word to use.

After lubić (to like), Polish often uses the infinitive to say that someone likes doing something.

So:

• lubi czytać = likes to read / likes reading
• lubi pływać = likes to swim / likes swimming
• lubi huśtać się = likes to swing

This is very natural in Polish. English can use either to swing or swinging, but Polish normally uses the infinitive here.

Się is a reflexive particle. In this sentence, it is part of the verb huśtać się, which means to swing oneself / to swing back and forth.

Without się, huśtać is usually transitive, meaning something like:

• huśtać dziecko = to swing a child
• huśtać łódkę = to rock a boat

But:

• huśtać się = to swing, to be on a swing, to sway oneself

So here się is necessary because the daughter is the one doing the swinging herself.

Sometimes yes. Się is fairly mobile in Polish, but not completely free.

In your sentence, lubi huśtać się na huśtawce is perfectly natural.

You may also hear:

• Nasza córka lubi się huśtać na huśtawce.

That also means the same thing and sounds natural.

In general, się often avoids standing at the very beginning of a clause, and it commonly appears after the verb or near it. For learners, the safest approach is to learn it together with the verb:

• huśtać się
• bać się
• uczyć się

Because Polish uses the preposition na with huśtawka to mean on the swing.

So:

• na huśtawce = on the swing

This is just the normal expression in Polish, much like English says on a swing.

Also, after na when it means location, Polish uses the locative case. That is why huśtawka changes to huśtawce.

It is the locative singular form of huśtawka.

The basic form is:

• huśtawka = swing

After na meaning on in the sense of location, you need the locative:

• na huśtawce = on the swing

So the pattern is:

• nominative: huśtawka
• locative: na huśtawce

Because Polish nouns change their endings depending on grammatical case.

Here:

• dictionary form: huśtawka
• after na for location: na huśtawce

Many feminine nouns ending in -ka do something similar in the locative singular:

• książka → w książce
• szafka → w szafce
• huśtawka → na huśtawce

So this is a common pattern, not something unique to this word.

Because they are closely related words.

• huśtać się = to swing
• huśtawka = a swing

They come from the same root, so Polish shows the relationship very clearly.

This is similar to English:

• to swing
• a swing

Seeing word families like this is very helpful in Polish vocabulary building.

Huśtać się is imperfective.

That makes sense because lubić usually describes a habit, general preference, or repeated activity, not one completed action.

So:

• Nasza córka lubi huśtać się na huśtawce = Our daughter likes swinging / likes to swing

Polish uses the imperfective here because the idea is general and ongoing.

A perfective verb would not fit as naturally in this kind of sentence about someone's usual likes.

A rough English-friendly guide is:

• córka ≈ TSOOR-ka

A few details:

• c in Polish sounds like ts
• ó sounds like oo as in food
• the stress is usually on the second-to-last syllable: CÓR-ka

So the stress falls on the first syllable here, because it is a two-syllable word.

A rough guide:

• huśtać się ≈ HOOSH-tach shen

More carefully:

• h is like English h
• u sounds like oo
• ś is a soft sh sound
• ą before ć is often pronounced approximately like on / om, but in real speech it can sound closer to a nasalized vowel
• ć is a soft ch-like sound
• się is usually pronounced roughly like shen or shyeh depending on speech style

Polish pronunciation is best learned by listening, but that approximation will get you fairly close.

A rough guide:

• huśtawce ≈ hoosh-TAF-tseh

Breakdown:

• huś = hoosh
• taw = roughly taf
• ce = tseh

Why taf? Because Polish w sounds like English v, and in a cluster like wc, it often becomes devoiced, so it sounds more like f.

Stress is on the second-to-last syllable:

• huś-TAW-ce

Yes. Polish word order is more flexible than English because endings show grammatical roles.

The neutral order here is:

• Nasza córka lubi huśtać się na huśtawce.

But you could also say:

• Na huśtawce nasza córka lubi się huśtać.
• Huśtać się na huśtawce lubi nasza córka.

These versions change the focus or emphasis, not the basic meaning.

For learners, the original order is the most natural and safest.

Yes, but it means something a little different.

• lubi huśtać się na huśtawce = she likes swinging on the swing
• lubi bawić się na huśtawce = she likes playing on the swing

So huśtać się focuses specifically on the swinging motion, while bawić się is broader and means to play.

Because the usual Polish expression is na huśtawce = on the swing.

Using w would suggest being inside something, and a normal playground swing is thought of as something you sit on, not in.

So:

• na huśtawce = correct and natural
• w huśtawce = generally not what you want here

Here it means likes in the general sense.

• lubi is the 3rd person singular form of lubić
• it matches nasza córka = our daughter

So:

• ja lubię = I like
• ty lubisz = you like
• on/ona lubi = he/she likes

In this sentence, lubi tells us what she generally enjoys doing.
