Najwyraźniej zebranie jest dziś.

Polish does not have articles, so there is no separate word for a or the.

That means zebranie can mean either:

• a meeting
• the meeting

Context tells you which one is meant. In a sentence like this, English often uses the meeting if both speaker and listener already know which meeting is being discussed.

Here najwyraźniej is a sentence adverb meaning something like:

• apparently
• evidently
• it seems
• clearly, from what we can tell

It shows that the speaker is drawing a conclusion from some evidence, not simply stating a plain fact with full confidence.

So the tone is closer to:

• Apparently, the meeting is today
• It looks like the meeting is today

than to a firm statement like The meeting is definitely today.

Historically, it comes from the same family as wyraźnie meaning clearly, and its form looks like a superlative. But in modern Polish, najwyraźniej is very often used as a fixed adverb meaning apparently / evidently.

So in this sentence, you should understand it as a natural expression of inference, not as a literal superlative.

Zebranie is a noun meaning meeting, assembly, or gathering.

In many everyday contexts, it means a somewhat organized or official meeting, for example:

• a staff meeting
• a parents’ meeting
• a committee meeting

It is a neuter noun, which is why it works with jest in the singular.

Jest is the 3rd person singular present tense of być, meaning to be.

So literally the structure is:

• zebranie = the meeting
• jest = is
• dziś = today

Polish normally keeps jest in a sentence like this.
You may sometimes hear shortened, elliptical versions in very informal speech, but the standard full sentence is:

Zebranie jest dziś.

Zebranie is in the nominative singular, because it is the subject of the sentence.

A quick breakdown:

• najwyraźniej — adverb
• zebranie — nominative singular noun
• jest — verb
• dziś — adverb

So only zebranie has a case here. The adverbs do not change for case.

Polish word order is fairly flexible, and different orders change emphasis more than basic meaning.

This version sounds natural because:

• Najwyraźniej comments on the whole sentence, so it fits well at the beginning.
• zebranie comes before jest dziś, making the meeting the topic.
• dziś comes late, so today feels like the key new information.

Other orders are possible, for example:

• Najwyraźniej dziś jest zebranie
• Zebranie jest dziś
• Dziś jest zebranie

These are not all identical in emphasis, but they are all understandable.

Yes. Dziś and dzisiaj both mean today.

The difference is mostly stylistic:

• dziś is shorter and very common
• dzisiaj is also completely normal, just a bit fuller in form

So you could also say:

Najwyraźniej zebranie jest dzisiaj.

Not exactly.

Both can be translated as meeting, but they are not always interchangeable:

• zebranie often suggests a more formal, organized meeting
• spotkanie is broader and can also mean a meeting in a social or casual sense

So zebranie is a good choice if you mean something like a scheduled group meeting, not just meeting someone.

Yes. If you remove it, you get:

Zebranie jest dziś.

That becomes a straightforward statement: The meeting is today.

With najwyraźniej, the speaker adds a nuance of inference or uncertainty based on evidence. Without it, the sentence sounds more direct and factual.
