To jest dobra wiadomość.

Word by word:

• To = this, that, or sometimes it depending on context
• jest = is
• dobra = good
• wiadomość = message, piece of news, or news item

So the sentence literally looks like This is good news or This is a good piece of news.

Because wiadomość is a feminine noun, and adjectives in Polish must agree with the noun in:

• gender
• number
• case

The basic nominative singular adjective endings are often:

• masculine: dobry
• feminine: dobra
• neuter: dobre

Since wiadomość is feminine, you need dobra wiadomość.

In Polish, many nouns ending in -a are feminine, but there are also feminine nouns with other endings. Wiadomość is one of them.

A very common pattern is that nouns ending in -ść are feminine, for example:

• wiadomość = news/message
• miłość = love
• radość = joy

So ta wiadomość and therefore dobra wiadomość.

Polish has no articles, so there is no separate word for a/an/the.

That means dobra wiadomość can mean:

• a good message
• the good message
• good news

The exact meaning depends on context.

In this sentence, to is not just a simple this. In Polish it is very often used in sentences that identify or define something:

• To jest dom. = This is a house.
• To jest Anna. = This is Anna.
• To jest dobra wiadomość. = This/That/It is good news.

So here to helps introduce what something is.

In full, careful Polish, To jest dobra wiadomość is completely correct.

But in everyday speech, people very often omit jest and say:

• To dobra wiadomość.

That sounds natural and common.

So:

• To jest dobra wiadomość. = full, explicit
• To dobra wiadomość. = very natural, slightly shorter

Both are correct.

Here wiadomość is in the nominative singular because the sentence is identifying something: This is good news.

With to jest, Polish normally uses the nominative:

• To jest nauczyciel.
• To jest książka.
• To jest dobra wiadomość.

You may have seen sentences with the instrumental after jest, such as:

• On jest nauczycielem. = He is a teacher.

That is a different pattern. After to jest, nominative is the normal choice.

A rough English-friendly guide:

• To ≈ toh
• jest ≈ yest
• dobra ≈ DOH-bra
• wiadomość ≈ vyah-DOH-moshch

A few useful pronunciation notes:

• j in Polish sounds like English y
• w sounds like English v
• ś is a soft sh-like sound
• ć is a soft ch-like sound

So wiadomość is one of those words that takes practice. Listening to native audio is especially helpful here.

The most neutral order is:

• To jest dobra wiadomość.

A very common shorter version is:

• To dobra wiadomość.

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

• Dobra wiadomość. = Good news. / That’s good news. in context
• Wiadomość jest dobra. = The message/news is good — this puts more focus on good
• To jest dobra wiadomość. = neutral identification

So yes, word order can change, but the meaning or emphasis may change too.

Because Polish and English treat news differently.

In English, news looks plural but usually behaves like an uncountable singular word:

• This is good news.

In Polish, wiadomość is a normal countable singular noun:

• jedna wiadomość = one message / one piece of news

So dobra wiadomość literally means a good piece of news or good news.

You would use the plural:

• To są dobre wiadomości.

Breakdown:

• To = these/this
• są = are
• dobre = good, plural non-masculine-personal
• wiadomości = messages/news items, plural

So:

• To jest dobra wiadomość. = This is good news.
• To są dobre wiadomości. = These are good news / These are good pieces of news.

Yes. Wiadomość can mean:

• message
• piece of news
• news item

For example:

• Dostałem wiadomość. = I got a message.
• To dobra wiadomość. = That is good news.

So the exact meaning depends on context. In your sentence, it is usually understood as good news.

Polish stress is usually on the second-to-last syllable of each word:

• TO
• JEST
• DO-bra
• wia-DO-mość

So the main natural rhythm is something like:

to jest DO-bra wia-DO-mość

That regular stress pattern is one of the nice things about Polish pronunciation.
