Lubię delikatny zapach tych kwiatów, bo nie jest zbyt ostry.

Because zapach is the direct object of lubię (I like), so it usually appears in the accusative case.

Here, zapach is a masculine inanimate noun. For masculine inanimate nouns, the accusative singular has the same form as the nominative singular:

• ten zapach — this smell/scent
• lubię ten zapach — I like this smell/scent

The adjective has to agree with the noun, so:

• delikatny zapach — a delicate scent

If this were a masculine animate noun, the accusative would look different. But zapach is inanimate, so delikatny stays the same.

Because tych kwiatów means of these flowers, and after zapach Polish normally uses the genitive to show what the smell belongs to or comes from.

So:

• zapach kwiatów — the smell of flowers
• zapach tych kwiatów — the smell of these flowers

Both words are in the genitive plural:

• te kwiaty — these flowers
• tych kwiatów — of these flowers

This is very common in Polish with nouns like:

• smak kawy — the taste of coffee
• kolor nieba — the color of the sky
• dźwięk muzyki — the sound of music

It is the genitive plural.

Breakdown:

• kwiaty is the nominative plural of kwiat (flower)
• kwiatów is the genitive plural
• te becomes tych in the genitive plural

So:

• te kwiaty — these flowers
• tych kwiatów — of these flowers

In the sentence, tych kwiatów depends on zapach:

• zapach tych kwiatów — the scent of these flowers

Both can mean because, but bo is more common in everyday speech and sounds natural here.

• bo — informal to neutral, very common in conversation
• ponieważ — more formal, more typical in writing or careful speech

So both are possible:

• Lubię delikatny zapach tych kwiatów, bo nie jest zbyt ostry.
• Lubię delikatny zapach tych kwiatów, ponieważ nie jest zbyt ostry.

The version with bo sounds very natural and conversational.

Zbyt means too or overly, while bardzo means very.

So:

• bardzo ostry — very sharp/strong
• zbyt ostry — too sharp/too strong

In this sentence:

• nie jest zbyt ostry = it is not too sharp/strong

That means the scent is pleasant because it is not excessively intense.

It does mean sharp, but like many adjectives, it has several related meanings depending on context.

With smells, tastes, and sensations, ostry can mean:

• sharp
• strong
• pungent
• harsh

So here zbyt ostry zapach is something like:

• too sharp a smell
• too strong a scent
• too pungent an odor

This is similar to English, where we can talk about a sharp smell or a strong scent.

In Polish, nie normally goes directly before the verb it negates.

So:

• jest — is
• nie jest — is not

You do not normally say jest nie for this meaning.

This is the standard Polish word order for negation with verbs:

• Lubię — I like

• Nie lubię — I do not like

• Jest — it is
• Nie jest — it is not

Jest refers to zapach (the scent/smell).

So the logic is:

• Lubię delikatny zapach tych kwiatów — I like the delicate scent of these flowers
• bo nie jest zbyt ostry — because it is not too sharp/strong

The implied subject of jest is zapach. In Polish, subject pronouns are often omitted when the meaning is clear from context.

You could make it more explicit, but it is not necessary:

• ...bo ten zapach nie jest zbyt ostry.

That is grammatically fine, but less natural than the original because Polish often avoids repeating obvious nouns.

Yes, but the meaning changes slightly.

• zapach — smell, scent; neutral and very common
• aromat — aroma; usually more pleasant, often richer or more refined

So:

• delikatny zapach kwiatów sounds very natural
• delikatny aromat kwiatów is possible, but sounds a bit more literary or elegant

For flowers, zapach is the most straightforward and natural choice.

Mostly yes, but in this sentence it is closer to:

• subtle
• gentle
• soft
• mild

So delikatny zapach means a scent that is light and pleasant, not overpowering.

In Polish, delikatny can describe many things:

• delikatny materiał — delicate fabric
• delikatna skóra — sensitive/delicate skin
• delikatny smak — a delicate/mild taste
• delikatny zapach — a delicate/subtle scent

So it works very naturally here.

Yes. Polish often leaves out subject pronouns when they are obvious from context.

In English you must say:

• because it is not too sharp

But in Polish, the subject can stay unstated:

• bo nie jest zbyt ostry

The form jest plus the context tells you what is meant. Here it clearly refers back to zapach.

This is one of the big differences from English. Polish often sounds more natural when it avoids unnecessary pronouns.

Polish word order is more flexible than English, but not every version sounds equally natural.

The original:

• Lubię delikatny zapach tych kwiatów, bo nie jest zbyt ostry.

This is natural and neutral.

You could also say:

• Bo nie jest zbyt ostry, lubię delikatny zapach tych kwiatów.

This is grammatical, but it puts stronger emphasis on the reason and sounds less neutral.

You might also hear:

• Lubię zapach tych kwiatów, bo jest delikatny i nie zbyt ostry.

That changes the structure a bit and emphasizes both qualities directly.

So yes, Polish word order is flexible, but the original sentence is probably the most natural everyday version.

A rough pronunciation guide for an English speaker:

• Lubię ≈ loo-BYEH
• delikatny ≈ deh-lee-KAHT-nih
• zapach ≈ ZAH-pakh (with a throaty kh sound at the end)
• tych ≈ roughly tikh or tikhh (with no English equivalent exactly)
• kwiatów ≈ KVYAH-toof
• bo ≈ boh
• nie ≈ nyeh
• jest ≈ yest
• zbyt ≈ roughly zbit
• ostry ≈ OS-trih

A few key sound notes:

• ę in lubię is nasalized, though in normal speech at the end of a word it is often pronounced close to e with slight nasal coloring.
• ch in zapach is like the ch in German Bach or Scottish loch.
• kw in kwiatów is pronounced together, like kv.
• rz and sz are not in this sentence, but tych contains a Polish y, which is not the same as English ee.

If you want, the safest rhythm is:

loo-BYEH deh-lee-KAHT-nih ZAH-pakh tikh KVYAH-toof, boh nyeh yest zbit OS-trih
