Nie chodzi o to, żeby mówić szybko, tylko żeby mówić wyraźnie i poprawnie.

It means something like It’s not about... or The point is not....

The verb chodzić o is a fixed expression meaning to be about, to concern, or to mean in essence. So chodzi here does not mean physical walking.

This is a very common Polish pattern: chodzi o to, że... / żeby... / kto... / jak...

The to points forward to the clause that comes next. So:

• chodzi o to = the point is about this
• żeby mówić szybko... = the content of that this

In natural English, we usually do not translate every word separately. We just say:

• It’s not about speaking quickly...
• The point is not to speak quickly...

Żeby introduces an idea of purpose, intention, desired result, or what should be done.

In this sentence, the speaker is talking about the goal or important thing, so żeby fits very naturally.

Compare:

• że = that in a factual sense
• żeby = so that / in order to / that in a purpose-like sense

A more formal alternative is aby, but żeby is the normal everyday choice.

After żeby, Polish can use an infinitive when the subject is general, unspecified, or understood from context.

So żeby mówić means:

• to speak
• in order to speak
• that one should speak

If you wanted to name a specific person, you would usually use a finite verb form instead:

• żebyś mówił wyraźnie = so that you speak clearly
• żeby dzieci mówiły wyraźnie = so that the children speak clearly

Here the statement is general, so the infinitive mówić is natural.

This is about aspect.

• mówić is imperfective: speaking as an ongoing activity or general habit
• powiedzieć is perfective: to say something once, to complete an utterance

The sentence is about how speaking should be done in general, not about saying one specific thing one time. That is why mówić is the right choice.

Yes, ale does mean but, but nie X, tylko Y is a very common pattern meaning:

• not X, but Y
• not this, rather that

It is especially used when the second part corrects or replaces the first part.

So:

• nie chodzi o to, żeby mówić szybko, tylko żeby mówić wyraźnie...

means the speaker is correcting the focus:

• not speed
• but clarity and correctness

So tylko is very natural here.

Because they are adverbs, not adjectives.

They describe how the action of mówić is done:

• mówić szybko = speak quickly
• mówić wyraźnie = speak clearly
• mówić poprawnie = speak correctly

If you wanted adjectives, they would describe nouns instead:

• szybka mowa = fast speech
• wyraźna wymowa = clear pronunciation
• poprawna polszczyzna = correct Polish

So the adverb forms are required because they modify the verb mówić.

Not always, but repeating it makes the sentence more balanced and explicit.

This version has a clear parallel structure:

• żeby mówić szybko
• żeby mówić wyraźnie i poprawnie

You may also hear a shortened version:

• Nie chodzi o to, żeby mówić szybko, tylko wyraźnie i poprawnie.

That is understandable and natural too. The full repeated version simply sounds a bit more careful and symmetrical.

Because Polish punctuation normally puts a comma before żeby, since it introduces a subordinate clause.

There is also a comma before tylko here because it separates two contrasting parts:

• żeby mówić szybko
• tylko żeby mówić wyraźnie i poprawnie

So the commas are standard and expected.

In the expression chodzić o, the preposition o takes the accusative.

So to here is accusative.

This is easy to miss because to looks the same in nominative and accusative, so there is no visible change in form.

This is worth remembering because o does not always take the same case in Polish. In different meanings or fixed expressions, it can behave differently.

Yes, very much. It is a common and useful structure for contrasting a wrong idea with the real point.

For example:

• Nie chodzi o to, żeby znać dużo słów, tylko żeby umieć ich używać.
• Nie chodzi o to, żeby pracować dłużej, tylko żeby pracować lepiej.

It is a very natural pattern in Polish and worth learning as a chunk.
