W tej kwiaciarni sprzedawczyni poleca róże i tulipany, bo dziś są świeże.

Because w meaning in takes the locative case when it describes location.

The basic dictionary form is:

• ta kwiaciarnia = this flower shop

After w, both words change:

• w tej kwiaciarni = in this flower shop

So here:

• ta → tej
• kwiaciarnia → kwiaciarni

This is a very common pattern in Polish: a preposition changes the case of the noun, and any adjective or demonstrative like ten / ta / to has to match it.

Sprzedawczyni means female salesperson, saleswoman, or shop assistant.

It is the feminine form related to:

• sprzedawca = male salesperson / seller
• sprzedawczyni = female salesperson / seller

Polish often marks gender in nouns more clearly than English does. Since the sentence uses sprzedawczyni, we know the person being talked about is a woman.

Because Polish often drops subject pronouns when they are not needed.

In English, you usually need she recommends. In Polish, the verb form already tells you it is he/she/it:

• polecam = I recommend
• polecasz = you recommend
• poleca = he/she/it recommends

And in this sentence, the subject noun sprzedawczyni is already there, so adding ona would be unnecessary unless you wanted special emphasis.

Poleca is the 3rd person singular present tense of polecać, which means to recommend.

So:

• sprzedawczyni poleca = the saleswoman recommends / is recommending

Why not poleci?

• polecać is imperfective
• polecić is perfective

That means:

• poleca = recommends, is recommending, recommends in general
• poleci = will recommend / recommends as a completed single action, depending on context

In this sentence, the present-time, ordinary meaning is needed, so poleca is the natural choice.

Because they are the direct objects of polecać, and polecać takes the accusative case.

The dictionary forms are:

• róża = rose
• tulipan = tulip

In the plural accusative here, we get:

• róże
• tulipany

A useful thing to know: for many plural nouns, especially inanimate ones, the accusative plural looks the same as the nominative plural.

So in this sentence:

• róże i tulipany = roses and tulips

It naturally means both are being recommended:

• róże = roses
• i = and
• tulipany = tulips

So the saleswoman recommends roses and tulips together.

Also, the later part są świeże is plural, which supports the idea that the statement is about the whole group.

Because the understood subject of that part is róże i tulipany, which is plural.

So Polish uses:

• są = are

not singular jest = is.

And świeże is the plural adjective form agreeing with the flowers.

So:

• są świeże = are fresh

Because róże i tulipany are things, not people, and Polish distinguishes a special plural type called masculine personal from all the other plurals.

Flowers are not masculine personal, so the adjective takes the non-masculine-personal plural form:

• świeże

This is the normal plural form used for things, animals, and mixed groups that are not all male persons.

So:

• róże są świeże
• tulipany są świeże
• róże i tulipany są świeże

all use świeże.

Yes. In this sentence, świeże refers to both roses and tulips.

The meaning is:

• the saleswoman recommends roses and tulips
• because today they are fresh

The plural verb są and plural adjective świeże both point back to the combined group róże i tulipany.

Bo means because.

So:

• bo dziś są świeże = because today they are fresh

As for the comma: in Polish, a comma before bo is normal and expected.

That is different from English, where you often would not put a comma before because in a sentence like this. Polish punctuation follows its own rules, so the comma here is correct.

Yes, dziś can move around because Polish word order is fairly flexible.

Here:

• bo dziś są świeże

puts a bit of focus on today.

You could also say:

• bo są dziś świeże

That also means because they are fresh today, but the emphasis shifts slightly.

So the sentence as written is natural, and the placement of dziś helps highlight the time.

Because Polish does not use articles like English the and a/an.

So Polish simply says:

• sprzedawczyni
• róże
• tulipany
• kwiaciarnia

and context tells you whether English should use the, a, or no article at all.

That is why one Polish sentence can correspond to several natural English versions, such as:

• In this flower shop, the saleswoman recommends roses and tulips because they are fresh today.
• In this flower shop, a saleswoman recommends roses and tulips because they are fresh today.

No, not completely. Polish word order is much freer than English word order because case endings show what each word is doing.

The given order is natural:

• W tej kwiaciarni = setting/place first
• sprzedawczyni = subject
• poleca = verb
• róże i tulipany = object
• bo dziś są świeże = reason

You could reorder parts for emphasis, for example:

• Sprzedawczyni w tej kwiaciarni poleca róże i tulipany, bo dziś są świeże.

That is still grammatical, but the focus changes a little. The original sentence feels very natural if you want to start by setting the scene: in this flower shop.
