Na obiad gotuję brokuł, kalafior i fasolę.

It means for lunch / for dinner in the sense of as the main meal.

A useful cultural note: Polish obiad does not match English meal words perfectly.

• In many contexts, obiad is the main cooked meal of the day.
• Depending on the household and schedule, that may be closer to lunch or dinner in English.

So na obiad is best understood as for the main meal rather than tied to one exact English meal word.

Because na obiad uses accusative and means something like for lunch/dinner or as lunch/dinner.

Compare:

• na obiad = for lunch/dinner
• na obiedzie = at lunch / at a dinner meal

So in your sentence, the speaker is saying what they are cooking for that meal, not that they are already at the meal.

Gotuję is:

• 1st person singular
• present tense
• from the verb gotować = to cook / to boil

So it means I cook, I am cooking, or I’m cooking, depending on context.

Polish present tense often covers both:

• I cook
• I am cooking

English has to choose more clearly; Polish often does not.

This is about aspect, which is very important in Polish verbs.

• gotować = imperfective
• ugotować = perfective

In this sentence, gotuję sounds natural because it focuses on the process or present activity: I’m cooking...

If you said ugotuję, it would usually mean something more like:

• I will cook
• I’ll cook and finish cooking

So:

• Na obiad gotuję... = I’m cooking ... for lunch/dinner.
• Na obiad ugotuję... = I will cook ... for lunch/dinner.

Because all three nouns are direct objects here, so they are in the accusative case.

But accusative looks different depending on the noun’s gender.

Masculine inanimate nouns

For many masculine inanimate nouns, accusative = nominative.

So:

• brokuł → brokuł
• kalafior → kalafior

Feminine nouns ending in -a

These usually change -a to -ę in the accusative.

So:

• fasola → fasolę

That is why the list looks mixed even though all three words are in the same case.

Yes. They are all in the accusative singular.

Here is the breakdown:

• brokuł — nominative singular: brokuł, accusative singular: brokuł
• kalafior — nominative singular: kalafior, accusative singular: kalafior
• fasola — nominative singular: fasola, accusative singular: fasolę

So the forms are different only because the nouns belong to different gender/type patterns.

In Polish, food words are often used in the singular when talking about an ingredient or a type of food.

So this sentence sounds like the speaker is naming what they are cooking as items/ingredients:

• brokuł
• kalafior
• fasolę

That is normal Polish usage.

But the exact number form can change depending on what you mean:

• brokuł can mean a broccoli head/piece or broccoli as an ingredient
• fasola can mean beans as a food category, not necessarily one single bean

So singular here does not automatically mean just one tiny item.

Yes, sometimes, depending on what exactly you want to express.

For example:

• gotuję brokuły = I’m cooking broccoli / broccoli pieces
• gotuję fasolkę = I’m cooking beans / green beans (depending on context and the exact word)

But the original sentence with singular nouns is still natural if you are naming the vegetables as ingredients or dishes.

The best choice depends on whether you are thinking of:

• the vegetable as a general food item
• several pieces
• a specific dish
• a particular variety of beans

Because Polish has no articles.

English needs words like:

• a
• an
• the

Polish does not.

So brokuł, kalafior, and fasolę can mean things like:

• a broccoli / the broccoli
• a cauliflower / the cauliflower
• some beans / the beans

The exact meaning comes from context, not from an article.

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

Your sentence:

• Na obiad gotuję brokuł, kalafior i fasolę.

is perfectly fine.

You could also hear:

• Gotuję na obiad brokuł, kalafior i fasolę.
• Brokuł, kalafior i fasolę gotuję na obiad.

These versions can shift the emphasis a bit, but the basic meaning stays the same.

Very roughly:

• Na obiad... first = sets the scene first: for lunch/dinner
• Gotuję... first = focuses first on the action: I’m cooking
• the vegetable list first = emphasizes the ingredients

With negation, Polish often changes the direct object from accusative to genitive.

So:

• Gotuję brokuł, kalafior i fasolę.
• Nie gotuję brokułu, kalafiora ani fasoli.

Notice the changes:

• brokuł → brokułu
• kalafior → kalafiora
• fasolę → fasoli

This is a very important Polish pattern: negation + object often triggers genitive.

The letter ę is a nasal vowel, but in real speech its pronunciation depends on position.

In these words:

• gotuję
• fasolę

the final -ę is often pronounced less nasally in everyday speech, sometimes close to a plain e, especially at the end of a word.

So learners often hear something like:

• gotuje
• fasole

But in careful spelling, it is still written ę.

Also note:

• ł in brokuł sounds like English w
• so brokuł sounds roughly like bro-koow

Because in a simple list, Polish normally works like English:

• commas between earlier items
• no comma before i = and

So:

• brokuł, kalafior i fasolę

is the normal punctuation.

A comma before i would usually appear only in special cases, not in an ordinary list like this.
