Moja nowa bluza jest za luźna.

Bluza usually means sweatshirt. In everyday Polish it can also refer more loosely to a casual top like a hoodie, but if you want to be specific, bluza z kapturem means hoodie.

It is a feminine noun, which is important because the other words in the sentence have to match it grammatically.

Because they both agree with bluza, which is a feminine singular noun.

• moja = my for a feminine singular noun
• nowa = new for a feminine singular noun
• bluza = a feminine singular noun

In Polish, possessives and adjectives usually match the noun in gender, number, and case.

Compare:

• mój nowy sweter = my new sweater
• moja nowa bluza = my new sweatshirt
• moje nowe buty = my new shoes

Because luźna is an adjective describing bluza, and it has to agree with that noun.

Since bluza is feminine singular, the adjective must also be feminine singular:

• luźny = masculine
• luźna = feminine
• luźne = neuter

So:

• sweter jest luźny = the sweater is loose
• bluza jest luźna = the sweatshirt is loose

Luźno is different: it is usually an adverb, meaning something like loosely or in a loose way, so it would not fit here.

Here za means too.

So za luźna means too loose.

This is a very common pattern in Polish:

• za mały = too small
• za duży = too big
• za drogi = too expensive
• za zimny = too cold

A useful comparison:

• bardzo luźna = very loose
• za luźna = too loose

So za suggests there is a problem or that something is more than desired.

Yes. Zbyt luźna also means too loose.

The difference is mostly one of style:

• za luźna = more common and natural in everyday speech
• zbyt luźna = a bit more formal or careful

So in normal conversation, Moja nowa bluza jest za luźna sounds very natural.

Jest is the 3rd person singular form of być = to be, so it means is.

In this sentence:

• Moja nowa bluza = my new sweatshirt
• jest = is
• za luźna = too loose

So the structure is very similar to English: My new sweatshirt is too loose.

In standard Polish, jest should be included here. In some very casual speech, people may occasionally drop forms of to be, but for learners it is best to keep jest.

No, Polish word order is fairly flexible, although some versions sound more natural than others.

The most neutral version is:

• Moja nowa bluza jest za luźna.

You could also hear:

• Ta moja nowa bluza jest za luźna. = This new sweatshirt of mine is too loose.
• Za luźna jest moja nowa bluza. = My new sweatshirt is too loose.
  This puts extra focus on za luźna.

So the basic meaning stays the same, but changing the order can change the emphasis.

A rough guide is LOOZH-na, but that is only approximate.

A few important sounds:

• ł sounds like English w
• u sounds like oo in food
• ź is a soft sound somewhat like the middle sound in measure, but softer
• na is pronounced clearly

So luźna is roughly woozh-na, except the first consonant is regular l, not ł. Since the word begins with lu-, think loo-zhna, with a soft zh sound.

If pronunciation matters to you, this is one of those words worth listening to from native audio, because ź does not have a perfect English equivalent.

Yes, most likely.

When talking about clothes, luźna usually means:

• too loose
• too baggy
• not fitting tightly enough

So this sentence most naturally means the sweatshirt is larger or looser than desired.

If you wanted to say something is physically loose in another sense, Polish might use different wording depending on the context. But for clothing, za luźna is exactly the kind of phrase you would expect.

Good question, because this helps you see the agreement pattern clearly.

Masculine singular:

• Mój nowy sweter jest za luźny.
  My new sweater is too loose.

Feminine singular:

• Moja nowa bluza jest za luźna.

Neuter singular:

• Moje nowe ubranie jest za luźne.
  My new garment/clothing item is too loose.

Plural:

• Moje nowe spodnie są za luźne.
  My new trousers are too loose.

Notice how the possessive, adjective, and final adjective all change to match the noun.
