Toplantı martta yapılacak.

Because the word is Mart (March) plus the locative suffix -DA, which means in / at / on depending on context.

In Turkish, that suffix changes shape for sound reasons:

• -da / -de
• -ta / -te

After a voiceless consonant like t, the suffix becomes -ta or -te. So:

• Mart + ta = Martta

The two t sounds stay next to each other in writing, so you get martta.

It is the locative case ending, which often means in, at, or on.

So:

• mart = March
• martta = in March

In this sentence, martta tells you when the meeting will happen.

In Turkish, names of months and days are usually not capitalized unless they begin a sentence or are part of an official name/date expression.

So in normal running text:

• mart = March
• pazartesi = Monday

That is different from English, where March and Monday are always capitalized.

Yapılacak comes from the verb yapmak (to do / to make), but here it is in a passive form plus the future tense.

Breakdown:

• yap- = do, make
• -ıl- = passive marker
• -acak = future tense

So yapılacak literally means will be done / will be made.

In the context of a meeting, a more natural English translation is often will be held.

Turkish often uses yapmak and its passive yapılmak in contexts where English prefers expressions like be held, take place, or sometimes be conducted.

So for events such as meetings, exams, or conferences:

• Toplantı yapılacak = The meeting will be held
• Sınav yapılacak = The exam will be held

This is very natural Turkish.

Because Turkish usually does not need a separate subject pronoun when the subject is already stated or clear.

Here, the subject is toplantı (the meeting), so there is no need for anything like English it.

Turkish commonly says:

• Toplantı martta yapılacak.

not

• O toplantı martta yapılacak. unless you specifically want to emphasize that meeting.

Turkish does not have articles like English a and the.

Whether toplantı means a meeting or the meeting depends on context. In this sentence, English often translates it as the meeting because it sounds more natural in context, but Turkish itself does not mark that with an article.

The order is:

• Toplantı = subject
• martta = time expression
• yapılacak = verb

A very common Turkish pattern is that the verb comes at the end.

So this sentence follows a normal Turkish structure: subject + time + verb

Turkish word order is flexible, but the final verb is very typical.

Yes. Turkish allows some flexibility in word order, often for emphasis.

For example:

• Toplantı martta yapılacak.
• Martta toplantı yapılacak.

Both are natural. The difference is mostly what gets slightly more emphasis:

• Toplantı martta yapılacak may feel like the topic is the meeting
• Martta toplantı yapılacak may put a bit more focus on in March

In Turkish, the 3rd person singular often has no extra personal ending in forms like this.

Compare:

• yapacağım = I will do
• yapacaksın = you will do
• yapacak = he/she/it will do

The same idea applies here:

• yapılacak = it will be done / held

So there is no missing ending; this is the normal 3rd person singular future form.

A simple pronunciation guide is:

• Toplantı ≈ top-lahn-tuh
• martta ≈ mart-tah
• yapılacak ≈ yah-puh-lah-jak

A few helpful notes:

• ı is not the English i sound; it is a more neutral, back vowel.
• In martta, both t sounds are pronounced.
• c in Turkish is pronounced like English j in jam, so -acak sounds like -ajak.

Yes. That also means The meeting will be held in March.

Compare:

• martta = in March
• mart ayında = in the month of March

Both are correct. Martta is shorter and very natural; mart ayında is a bit more explicit.
