Pisownia jest ważna, ale w codziennej rozmowie jeszcze ważniejsza bywa dobra wymowa.

Because pisownia is a feminine noun in Polish, so the adjective must match it.

• pisownia = feminine
• ważna = feminine form of ważny meaning important

So:

• ważny = important, masculine
• ważna = important, feminine
• ważne = important, neuter

The same agreement happens later in the sentence:

• dobra wymowa because wymowa is also feminine
• ważniejsza because it refers to wymowa, also feminine

Pisownia means spelling or orthography.

In this sentence, it refers to how words are written correctly.

It is different from:

• pisać = to write
• pismo = writing, script, letter, handwriting, or a written document depending on context
• pisownia = spelling

So pisownia is specifically about the correct written form of words, not the act of writing in general.

After the preposition w meaning in, Polish usually uses the locative case when talking about location or context.

So:

• codzienna rozmowa = everyday conversation
• w codziennej rozmowie = in everyday conversation

Both words change:

• codzienna → codziennej
• rozmowa → rozmowie

This is because they are feminine singular in the locative case.

A learner may find it helpful to remember the whole phrase as a chunk:

• w rozmowie = in conversation
• w codziennej rozmowie = in everyday conversation

It means even more important.

The adjective ważna is the basic form:

• ważna = important

Its comparative form is:

• ważniejsza = more important

Then jeszcze adds emphasis:

• jeszcze ważniejsza = even more important

In English, jeszcze can often mean still, yet, or even, depending on context. Here it clearly means even.

This is a very natural question, because bywa adds an important nuance.

• jest = is
• bywa = is sometimes / tends to be / can be / is often

So:

• ważniejsza jest dobra wymowa would sound more definite: good pronunciation is more important
• ważniejsza bywa dobra wymowa sounds softer and more nuanced: good pronunciation is often more important or can be even more important

It suggests a general tendency rather than an absolute rule.

Also, bywa is related to the verb być (to be), but it has this special habitual sense.

Yes, bywa comes from bywać, which is related to być.

A useful way to think about it:

• być = to be
• bywać = to be from time to time, to happen sometimes, to tend to be

So bywa is not the normal present tense of być. It comes from a related imperfective verb with a habitual or repeated meaning.

Examples:

• On jest zmęczony. = He is tired.
• On bywa zmęczony po pracy. = He is sometimes / often tired after work.

In your sentence, bywa makes the statement sound less absolute and more observational.

Wymowa means pronunciation.

It is not exactly the same as accent.

• wymowa = pronunciation
• akcent = accent

So dobra wymowa means good pronunciation, not necessarily a good accent.

A person can have:

• good wymowa = they pronounce words clearly/correctly
• a foreign akcent = they still sound non-native

Those are related, but not identical.

Polish word order is much more flexible than English word order, and different orders can change emphasis.

In this sentence:

• jeszcze ważniejsza bywa dobra wymowa

the speaker puts emphasis first on the idea of being even more important. Only after that do we get dobra wymowa.

A more neutral order could also be:

• dobra wymowa bywa jeszcze ważniejsza

That version foregrounds good pronunciation first.

So the original word order is not random. It helps shape emphasis and style. Polish often uses word order to highlight what the speaker wants to stress.

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

So:

• Pisownia jest ważna can mean Spelling is important
• dobra wymowa can mean good pronunciation or, depending on context, the good pronunciation

The exact meaning comes from context rather than an article.

This is one of the big differences between Polish and English. English speakers often look for the, but in Polish it simply is not there.

Ale means but.

It connects two contrasting ideas:

• Pisownia jest ważna = Spelling is important
• ale... dobra wymowa... = but... good pronunciation...

So the sentence says that spelling matters, but in everyday conversation, pronunciation may matter even more.

It is a straightforward conjunction here.

Here is a simple pronunciation guide for an English speaker:

• Pisownia ≈ pee-SOV-nya
• jest ≈ yest
• ważna ≈ VAZH-na
• ale ≈ AH-le
• w = like v
• codziennej ≈ tso-DZYEN-ney
• rozmowie ≈ roz-MO-vye
• jeszcze ≈ YESH-che
• ważniejsza ≈ vazh-NYEY-sha
• bywa ≈ BIH-va
• dobra ≈ DO-bra
• wymowa ≈ vih-MO-va

A few pronunciation points:

• w in Polish is pronounced like English v
• rz in ważna sounds like zh in measure
• cz sounds like ch, but in jeszcze the cluster szcz is a bit tighter: yesh-che
• j in Polish sounds like English y
• nie in ważniejsza gives a nye sound

Rozmowa most directly means conversation.

So:

• w codziennej rozmowie = in everyday conversation

In natural English translation, people may sometimes say:

• in everyday speech
• in everyday conversation

Both can work depending on style, but the Polish word here is literally conversation.

If the sentence had meant speech more generally, it might have used another word depending on the exact nuance.

Yes. Even if the core meaning stays the same, the nuance of bywa allows several good translations.

Possible translations include:

• Spelling is important, but in everyday conversation good pronunciation is often even more important.
• Spelling is important, but in daily conversation good pronunciation can be even more important.
• Spelling matters, but in everyday conversation good pronunciation may matter even more.

These all capture the same general idea, but:

• often reflects the habitual sense of bywa
• can be reflects possibility
• may reflects a softer, less absolute claim

So if a learner sees different English versions, that is normal.
