To jest nowa zabawka dla naszej córki.

In this sentence, to means this or it in the sense of identifying something.

So To jest nowa zabawka... literally means This is a new toy...

A useful thing to know is that Polish to is very often used in simple X is Y sentences:

• To jest dom. = This is a house.
• To jest moja siostra. = This is my sister.

It is not changing for gender here, which is why you see to, not ta.

Jest is the 3rd person singular form of the verb być = to be.

So:

• jest = is

In To jest nowa zabawka, it connects to and nowa zabawka, just like is in English:

• This is a new toy.

Polish often drops subject pronouns like he, she, or it, but here jest is still needed in a normal full sentence.

Because nowa has to agree with zabawka.

In Polish, adjectives must match the noun in:

• gender
• number
• case

Zabawka is:

• feminine
• singular
• nominative here

So the adjective must also be feminine singular nominative:

• nowa zabawka = new toy

Compare:

• nowy dom = new house masculine
• nowa zabawka = new toy feminine
• nowe okno = new window neuter

A very common clue in Polish is the noun ending.

Most nouns ending in -a are feminine, and zabawka is one of them.

So:

• zabawka = feminine noun

That affects the form of words around it, such as adjectives:

• nowa zabawka
• mała zabawka
• ładna zabawka

Be careful, though: not every noun ending in -a is feminine, but it is a very strong general rule.

Dla means for.

So:

• dla naszej córki = for our daughter

It shows who the toy is intended for.

This is a very common preposition in Polish:

• To jest prezent dla mamy. = This is a present for Mom.
• Mam coś dla ciebie. = I have something for you.

Because the preposition dla requires the genitive case.

So after dla, both the adjective and the noun must change form:

• nasza córka = our daughter nominative
• dla naszej córki = for our daughter genitive

Here is the breakdown:

• nasza → naszej
• córka → córki

This is one of the most important things to learn in Polish: prepositions often force a specific case.

They are in different cases because they do different jobs in the sentence.

• nowa zabawka is in the nominative
• naszej córki is in the genitive

Why?

Nowa zabawka is the thing being identified:

• This is a new toy

After dla, Polish uses the genitive:

• for our daughter = dla naszej córki

So the sentence mixes cases naturally:

• To jest
  • nominative
• dla
  • genitive

Because Polish has no articles.

English says:

• This is a new toy
• This is the new toy

Polish usually just says:

• To jest nowa zabawka

The exact meaning of a or the is usually understood from context.

This is normal in Polish, so you do not need to add anything for articles.

Yes, you may hear that, especially in casual speech, headlines, or very context-based situations. But the full standard sentence is:

• To jest nowa zabawka dla naszej córki.

Leaving out jest can sound a bit more compressed or conversational:

• To nowa zabawka dla naszej córki.

As a learner, it is safest to use jest until you get more comfortable with natural omissions.

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

The sentence:

• To jest nowa zabawka dla naszej córki.

is a very neutral, natural order.

But other orders are possible, depending on emphasis:

• Dla naszej córki to jest nowa zabawka.
• To jest dla naszej córki nowa zabawka.

The meaning stays similar, but the focus can shift. Polish often uses word order for emphasis rather than basic grammar.

For learners, the original version is the best neutral pattern to remember.

This is a very common question.

• to is used in identification sentences like This is...
• ta is a feminine demonstrative adjective meaning this before a feminine noun

So:

• To jest nowa zabawka. = This is a new toy.
• Ta zabawka jest nowa. = This toy is new.

In the first sentence, to stands on its own. In the second, ta directly modifies zabawka.

Because zabawka is feminine, if you say this toy, you need ta zabawka.

In modern Polish, ó is pronounced the same as u.

So córki sounds roughly like:

• TSOOR-kee

A few pronunciation notes:

• c in Polish sounds like ts
• ó sounds like u in rule
• r is rolled or tapped
• stress is usually on the second-to-last syllable, so CÓR-ki

Also:

• naszej is roughly NA-shay
• zabawka is roughly za-BAF-ka or za-BAV-ka, depending on how you hear the voicing in connected speech

It is the normal and correct way in this sentence.

The basic dictionary forms are:

• nasza = our
• córka = daughter

But after dla, you need genitive:

• naszej córki

So if you want to say for our daughter, this is the form you need.

You can think of it like this:

• base form: nasza córka
• after dla: dla naszej córki

That pattern will help with many other phrases too:

• dla mojej siostry = for my sister
• dla naszego syna = for our son
