Çalışma koşulları sözleşmede yazıyor.

A simple breakdown is:

• çalışma koşulları = the subject, working conditions
• sözleşmede = a location phrase, in the contract
• yazıyor = the verb, here meaning is written / it says

So the structure is basically:

[Subject] + [Location] + [Verb]

That is a very common Turkish sentence pattern.

Here, çalışma means work / working, not study.

It comes from the verb çalışmak, which can mean both to work and to study, depending on context. In this sentence, because it is followed by koşulları and the meaning is already about job conditions, it clearly means working.

Grammatically, çalışma is not a finite verb here. It is being used like a noun, as part of the noun phrase çalışma koşulları = working conditions.

Because çalışma koşulları is a noun compound.

In Turkish, when one noun modifies another noun, the second noun usually takes a special ending, often called the 3rd person possessive suffix:

• çalışma koşulu = working condition
• çalışma koşulları = working conditions

So the -ı here is part of that compound structure. It is not there randomly.

This pattern is very common in Turkish:

• otobüs durağı = bus stop
• şehir merkezi = city center
• iş ilanı = job ad

So çalışma koşulları is the normal Turkish way to say working conditions.

Not in this sentence.

That is a very common confusion, because the form can look similar. But here koşulları is the subject of the sentence, not a direct object, so this -ı is part of the noun compound, not the accusative.

Compare:

• Çalışma koşulları sözleşmede yazıyor.
  Here çalışma koşulları = working conditions as a subject.

• Çalışma koşullarını okudum.
  Here koşullarını has an accusative ending because it is the object: I read the working conditions.

So in your sentence, think of koşulları as a fixed part of the phrase çalışma koşulları.

Because -de is the locative case, which means in / on / at.

• sözleşme = contract
• sözleşmede = in the contract

So sözleşmede yazıyor means it is written in the contract or it says so in the contract.

This case is extremely common in Turkish:

• evde = at home
• okulda = at school
• masada = on the table

Because in Turkish, inanimate plural subjects often take a singular verb.

So even though koşulları means conditions and is plural, yazıyor is still normal.

This is very natural in Turkish:

• Kitaplar masada duruyor. = The books are on the table.
• Sorular kitapta bulunuyor. = The questions are in the book.

Using a plural verb is much more common with people, and even then Turkish often still allows the singular.

So Çalışma koşulları sözleşmede yazıyor is completely normal.

Yes, literally yazıyor is the present progressive of yazmak = to write.

But Turkish often uses yazıyor with texts, signs, labels, documents, and screens to mean:

• it says
• it is written
• it appears in writing

For example:

• Ne yazıyor? = What does it say? / What is written there?
• Kapıda yasak yazıyor. = It says forbidden on the door.

So in your sentence, sözleşmede yazıyor is a natural way to say that the contract contains that information in writing.

Yes. Çalışma koşulları sözleşmede yazılı is also correct.

The difference is roughly this:

• yazıyor = it says / it is written there
• yazılı = written, in written form

So:

• Çalışma koşulları sözleşmede yazıyor.
  sounds like the contract says / shows the working conditions

• Çalışma koşulları sözleşmede yazılı.
  sounds more like the working conditions are written in the contract

Both are natural, but yazılı can sound a bit more formal or static.

Yes. This is a normal Turkish order.

Turkish usually puts the verb at the end, and that is exactly what happens here:

• Çalışma koşulları
  • sözleşmede
    • yazıyor

Turkish word order is somewhat flexible, but the verb-final order is the safest and most neutral pattern for learners.

So this sentence is a good model to follow.

Because Turkish does not have a definite article like English the.

Whether something means a, the, or just a general idea usually depends on:

• context
• word order
• case marking
• what the speaker and listener already know

So çalışma koşulları can naturally mean the working conditions without needing a separate word for the.

That is completely normal in Turkish.

The main ones are:

• ç = like ch in church
• ş = like sh in shoe
• ö = similar to German ö or French eu
• ı = the dotless i, a sound English does not really have; keep the tongue high and the lips unrounded

Rough guides:

• çalışma ≈ cha-lush-ma
• koşulları ≈ ko-shul-la-ruh
• sözleşmede ≈ soz-lesh-me-de
• yazıyor ≈ ya-zuh-yor

The hardest sound for most English speakers is ı. It is not the same as i in machine. Learning that contrast is very important in Turkish.
