Şayet kontenjan dolarsa ikinci bir oturum açacağız.

Şayet means if. In this sentence, it introduces the condition:

• Şayet kontenjan dolarsa... = If the quota/capacity fills up...

It is correct and natural, but it sounds a bit more formal or written than eğer, which is another very common word for if.

So these are very similar:

• Şayet kontenjan dolarsa...
• Eğer kontenjan dolarsa...

In everyday speech, many people would more often use eğer, or sometimes no separate if word at all if the conditional ending already makes the meaning clear.

Dolarsa comes from the verb dolmak, meaning to become full / to fill up.

It breaks down like this:

• dol- = verb stem
• -ar = aorist/general-future type marker
• -sa = conditional if

So:

• dolar = it fills up / it becomes full
• dolarsa = if it fills up / if it becomes full

In Turkish, this -sa / -se conditional ending is very common for if clauses.

A few similar examples:

• Gelirse = if he/she comes
• Yağarsa = if it rains
• Olursa = if it happens / if there is one

So kontenjan dolarsa literally means if the capacity fills up.

That is very normal in Turkish. In conditional clauses, Turkish often uses the aorist + conditional form to talk about future possibilities.

So even though the sentence is about a future situation, Turkish says:

• kontenjan dolarsa = if the quota fills up

rather than using a straightforward future form there.

This is similar to English in a way. English also often says:

• If it rains tomorrow, we will stay home

not If it will rain tomorrow...

So Turkish and English are actually behaving similarly here: the if-clause does not normally take the plain future tense.

Kontenjan means something like:

• quota
• capacity
• number of available places/spots
• allocated seats

In this sentence, it most likely refers to the number of available places in a course, seminar, event, or session.

So kontenjan dolarsa means:

• if all available places are taken
• if capacity is reached
• if the quota fills up

It is a very common word in Turkish for enrollment limits, reservations, university places, event spots, and similar contexts.

İkinci bir oturum means a second session or another session as the second one.

Breakdown:

• ikinci = second
• bir = a / one
• oturum = session

The word bir here is not just the number one. Very often in Turkish, bir works like a/an, or it adds the sense of another or an additional.

So:

• ikinci oturum = second session
• ikinci bir oturum = a second session / an additional second session

The version with bir can sound a little more natural or a little softer in some contexts. It emphasizes that they will open an extra session.

Yes, literally it is we will open a session, but in natural English here it usually means:

• we will open a second session
• we will add another session
• we will hold a second session
• we will start a second session

So:

• oturum açmak can literally be to open a session
• but in context it often means to create/start/offer a session

Be careful, because oturum açmak is also used in technology/computing for to log in / sign in.
Here, because of ikinci bir oturum, it clearly means an additional event/class/session, not logging in.

Turkish often leaves out subject pronouns because the verb ending already shows who the subject is.

Here:

• açacağız = we will open

The ending -acağız / -eceğiz tells you the subject is we.

So biz is unnecessary unless you want extra emphasis.

Compare:

• İkinci bir oturum açacağız. = We will open a second session.
• Biz ikinci bir oturum açacağız. = We will open a second session.
  (with extra emphasis on we)

This is very common in Turkish.

Yes, Turkish word order is flexible, although some orders sound more neutral than others.

This sentence has a very natural structure:

• Şayet kontenjan dolarsa ikinci bir oturum açacağız.

A very common pattern is:

• [if-clause] + [main clause]

You could also say:

• İkinci bir oturum açacağız, şayet kontenjan dolarsa.

That is understandable, but it may sound a bit more marked or stylistically different. In ordinary usage, putting the condition first is very common and often the most natural.

So the original word order is a standard, natural choice.

Yes, slightly.

Both mean if, but:

• eğer = very common, neutral
• şayet = a bit more formal, written, or literary

So if a learner wants the most everyday alternative, they could say:

• Eğer kontenjan dolarsa ikinci bir oturum açacağız.

And in many situations, Turkish can even omit şayet/eğer entirely:

• Kontenjan dolarsa ikinci bir oturum açacağız.

Because -sa / -se already shows the conditional meaning, that version is also perfectly natural.

Açacağız is pronounced approximately like a-cha-a-zuhz or a-cha-yuhz, depending on accent and how carefully someone speaks.

A few useful points:

• ç sounds like ch in church
• c sounds like j in jam
• ğ usually does not sound like a hard consonant in modern Turkish

In açacağız, the ğ mainly lengthens or smooths the vowel before it. So learners should not try to pronounce it like an English g.

The word is from:

• aç- = open
• -acak / -ecek = future
• -ız / -iz type personal ending for we

So açacağız = we will open.

Not exactly from the Turkish as written.

The thing that fills up in the sentence is kontenjan:

• kontenjan dolarsa = if the capacity/quota fills up

So the idea is not that the session itself fills up grammatically, but that the available places reach capacity. In natural English, though, people often say:

• If this session fills up, we’ll open another one.

That can express almost the same real-world meaning. But the Turkish sentence specifically says the capacity/quota fills up, not oturum.

So for understanding the Turkish structure, it is better to keep in mind:

• kontenjan = capacity/available spots
• oturum = session
