Toplantı yeter sayısı bugün oluştu.

It is a fixed formal expression meaning quorum in the sense of the minimum number of people required for a meeting to be valid.

Literally, the parts are roughly:

• toplantı = meeting
• yeter = enough / sufficient
• sayısı = its number / number

But you should learn toplantı yeter sayısı as a whole term, not just word by word. In legal, official, and organizational Turkish, it is the standard way to say meeting quorum.

Because Turkish often forms noun compounds by putting a special ending on the second noun. Here, sayı becomes sayısı.

So even though -sı looks like a possessive ending, in expressions like this it is part of the compound structure. English speakers often expect something more like meeting enough number, but Turkish packages this idea differently.

A useful way to think of it is:

• sayı = number
• sayısı = the number of X / X-number in a compound expression

So toplantı yeter sayısı is the established compound for meeting quorum.

Because this sentence uses the standard compound form, where the first noun stays bare:

• toplantı yeter sayısı = meeting quorum

If you say toplantının yeter sayısı, that sounds more like the quorum of the meeting or this specific meeting’s required number, with a more explicit possessive relationship.

Both can make sense in context, but toplantı yeter sayısı is the usual dictionary-style term.

Oluştu is the past tense of oluşmak, which means things like:

• to form
• to come into being
• to take shape
• to be constituted

In this sentence, it means that the quorum came into existence or was reached.

So although a very literal translation would be The meeting quorum formed today, natural English usually says The quorum was reached today.

Because oluşmak is more specific than olmak.

• olmak = to be / to become / to happen
• oluşmak = to form, to come into existence, to be constituted

With something like a quorum, oluştu sounds more precise and formal: the required number has now come together.

Using oldu would be less idiomatic here. Native speakers are more likely to use verbs such as:

• oluştu
• sağlandı = was achieved / secured
• sometimes tamamlandı depending on context

The subject is toplantı yeter sayısı.

The structure is:

• Toplantı yeter sayısı = subject
• bugün = time adverb, today
• oluştu = verb, formed / was reached

So grammatically, the sentence is saying that the quorum did something: it formed.

Because the grammatical subject is singular.

Even though a quorum refers to multiple people in real life, the noun phrase toplantı yeter sayısı is grammatically one thing: the quorum.

So the verb is singular:

• oluştu = it formed

Not plural.

This is similar to English using singular verbs with the quorum, the group, or the committee in many contexts.

That is a very common question for English speakers.

Turkish uses the simple past -DI very naturally for a completed event earlier today:

• bugün oluştu = it formed today / it was reached today

English often prefers the present perfect in this situation, but Turkish does not follow the same rule. So bugün oluştu is completely normal.

In other words:

• English: The quorum has been reached today or was reached today
• Turkish: Toplantı yeter sayısı bugün oluştu

Yes, Turkish word order is flexible.

The neutral order here is:

• Toplantı yeter sayısı bugün oluştu.

But you could also hear:

• Bugün toplantı yeter sayısı oluştu.
• Toplantı yeter sayısı oluştu bugün.

These are all possible, but they have slightly different emphasis.

In the original sentence, bugün right before the verb gives a natural focus to today. It feels a bit like: The quorum was reached today.

It is grammatically active, not passive.

There is no passive ending on the verb. The verb is oluşmak, which is an intransitive verb meaning to form or to come into being.

However, when we translate it into natural English, we often use a passive-style expression:

• Turkish: Toplantı yeter sayısı bugün oluştu.
• Natural English: The quorum was reached today.

So the Turkish grammar is active, but the best English translation may sound passive.

It is fairly formal and especially common in official, legal, parliamentary, corporate, or procedural contexts.

You are likely to see toplantı yeter sayısı in:

• meeting rules
• bylaws
• legal texts
• minutes
• parliamentary language

In casual speech, people might say something less technical, such as:

• Bugün yeterli sayı sağlandı.
• Bugün yeterli kişi toplandı.
• Toplantı için yeterli kişi sayısına ulaşıldı.

But for the technical idea of quorum, toplantı yeter sayısı is the correct formal term.
