Spotkanie się udało.

Because spotkanie is a neuter singular noun in Polish.

In the past tense, Polish verbs agree with the subject in gender and number:

• udał się — masculine singular
• udała się — feminine singular
• udało się — neuter singular
• udały się — non-masculine personal plural
• udali się — masculine personal plural

Since spotkanie is neuter, the correct form is udało się.

In this sentence, się is part of the verb expression udać się.

You should learn udać się as a whole, because it means things like:

• to succeed
• to turn out well
• to go well

So Spotkanie się udało is not built from a simple verb udać plus a separately meaningful się in the way an English learner might expect. Here, się is a fixed part of the idiom.

A useful comparison:

• Plan się udał. — The plan succeeded / worked out.
• Impreza się udała. — The party went well.
• Spotkanie się udało. — The meeting went well.

No. That is a very common confusion.

Spotkanie się udało means the meeting was successful or went well.

If you want to say the meeting took place / happened, you would usually say:

• Spotkanie się odbyło.

So compare:

• Spotkanie się odbyło. — The meeting took place.
• Spotkanie się udało. — The meeting went well / was a success.

The first is about whether it happened at all.
The second is about how well it went.

Spotkanie się udało is natural, and so is:

• Spotkanie udało się.

But Udało się spotkanie is unusual in normal speech unless there is a special context.

Polish word order is more flexible than English, but not completely free. In this sentence, the noun spotkanie is usually the topic, so putting it first sounds natural.

Most neutral versions:

• Spotkanie się udało.
• Spotkanie udało się.

Both mean the same thing, but the first one is very common and natural.

Yes. Spotkanie is the grammatical subject.

You can see that because the verb agrees with it:

• spotkanie — neuter singular
• udało — neuter singular past form

So grammatically, this is something like:

• The meeting succeeded
• The meeting turned out well

Even if the most natural English translation is The meeting went well, the Polish grammar still treats spotkanie as the subject.

The dictionary form is udać się.

Udało is the past tense, neuter singular form of that verb.

A few related forms:

• udać się — perfective infinitive
• udał się — he/it (masculine) succeeded
• udała się — she/it (feminine) succeeded
• udało się — it (neuter) succeeded
• udały się — they succeeded

This verb is usually learned as a set phrase: udać się.

Because Polish past tense works differently from English.

In English, you often need a separate verb such as was:

• The meeting was successful.

In Polish, the past form is built directly into the verb:

• udało się

That one form already contains past tense information, and it also shows gender/number agreement.

So there is no need for a separate word corresponding to English was here.

No, not in this form.

There is another very common pattern with udać się:

• Udało mi się... — I managed to...
• Udało mu się... — He managed to...

For example:

• Udało mi się skończyć pracę. — I managed to finish the work.

But Spotkanie się udało is a different structure. Here, the subject is spotkanie, and the meaning is that the meeting itself went well or was successful.

So:

• Udało mi się spotkać z nim. — I managed to meet him.
• Spotkanie się udało. — The meeting went well.

Those are related uses of the same verb, but they are not the same sentence pattern.

Yes, it matters.

Udać się is perfective. That means it presents the event as a completed whole, with a result.

So Spotkanie się udało means that the meeting is over, and the result is that it turned out successfully.

Its imperfective partner is udawać się, but that is used in different contexts, for example for repeated success or ongoing situations:

• Ten plan zwykle się udaje. — This plan usually works.
• Nic mi się nie udawało. — Nothing was going well for me.

For a single completed meeting, udało się is the normal choice.

Yes, very often.

This pattern is common with events, plans, activities, and attempts. For example:

• Egzamin się udał. — The exam went well.
• Impreza się udała. — The party was a success.
• Projekt się udał. — The project succeeded.
• Wakacje się udały. — The vacation went well.

Notice how the verb changes to match the gender and number of the noun:

• impreza → udała się (feminine)
• projekt → udał się (masculine)
• spotkanie → udało się (neuter)
• wakacje → udały się (plural)

In careful pronunciation, się is approximately like shyeh with a nasal ending, though there is no perfect English equivalent.

A few practical points for learners:

• si before ę sounds soft, roughly ś
• ę at the end of a word is often not pronounced as a full nasal vowel in everyday speech

So in normal speech, się may sound closer to:

• sheh
• sheng (very roughly, depending on the speaker and context)

You do not need to over-pronounce the nasal vowel. The most important thing is to keep the s soft: śe / śę, not a hard English see.

It can correspond to both, depending on context, but in natural English the best translation is often:

• The meeting went well.
• The meeting was a success.

A very literal translation like The meeting succeeded is understandable, but it sounds less natural in English.

So for grammar, it helps to think of Polish as saying something like the meeting succeeded, but for fluent translation, English usually prefers went well or was a success.
