İlk yardım eğitim merkezi her kursiyeri kaydetti.

Because the most neutral Turkish word order is Subject + Object + Verb.

So this sentence is:

İlk yardım eğitim merkezi + her kursiyeri + kaydetti
subject + direct object + verb

English usually puts the verb earlier, but Turkish normally saves it for the end.

A simple breakdown is:

• İlk yardım eğitim merkezi = the subject
• her kursiyeri = the direct object
• kaydetti = the verb

So the sentence structure is:

[The first aid training center] [registered every trainee]

Even if you already know the meaning, this is useful because Turkish often signals roles through endings, not just word order.

That -i is not the accusative here.

In eğitim merkezi, you have a very common Turkish noun-compound pattern. The second noun often takes a possessive-looking ending:

• eğitim merkezi = training center
• literally something like education/training center

So merkezi is part of the noun phrase itself. It is the normal form of the compound, not a sign that the word is an object.

Other similar examples:

• otobüs durağı = bus stop
• alışveriş merkezi = shopping center
• sağlık ocağı = health clinic

So in this sentence, merkezi is just the subject noun inside the compound.

Yes. It functions as one complete subject phrase.

Turkish often stacks modifiers before the main noun. Here the main idea is eğitim merkezi = training center, and ilk yardım narrows down what kind of training center it is.

So the whole phrase works as:

first aid training center

This kind of long noun phrase is very normal in Turkish, especially in institutional names and formal contexts.

Because kursiyeri is the direct object, and it takes the accusative ending -i.

In Turkish, a specific or fully identified direct object usually takes the accusative:

• kursiyer = trainee / course participant
• kursiyeri = the trainee / the trainee as a specific direct object

With her (every/each), the object is understood as a complete, specific set, so the accusative is expected:

• her kursiyeri kaydetti = registered every trainee

So the -i on kursiyeri is there because it is the object of the verb.

Because her is followed by a singular noun in Turkish.

So:

• her kursiyer = every trainee / each trainee

not

• her kursiyerler or her kursiyerleri

This is different from English, where every also uses a singular noun, so that part is actually quite similar:

• every trainee
• not every trainees

Then Turkish adds the accusative ending because the noun is the direct object:

• her kursiyer
  • -i → her kursiyeri

It comes from the dictionary form kaydetmek, which means to register / to record.

Formation:

• kaydetmek = infinitive
• remove -mek → kaydet- = verb stem
• add past tense -di / -dı / -du / -dü / -ti / -tı / -tu / -tü

Because the stem ends in t, the past ending appears as -ti:

• kaydet-
  • -ti → kaydetti

The subject is third person singular, and Turkish does not need an extra ending here beyond the tense form.

So kaydetti means he/she/it registered.

Because the verb stem already ends in t:

• kaydet-

And the past tense ending here begins with t:

• -ti

So they come together:

• kaydet-
  • -ti → kaydetti

This is completely normal in Turkish spelling.

Yes, Turkish word order is flexible, because endings help show what each part is doing.

For example, you could move parts around for emphasis. But the neutral, straightforward version is:

İlk yardım eğitim merkezi her kursiyeri kaydetti.

If you front the object, you would emphasize it more:

Her kursiyeri ilk yardım eğitim merkezi kaydetti.

That can sound like It was every trainee that the first aid training center registered or put focus on every trainee.

So the original sentence is the most neutral and textbook-like order.

Turkish does not have articles like English the and a/an.

So nouns often appear without any article word, and you understand the meaning from context.

That means:

• eğitim merkezi can mean a training center or the training center
• the exact choice depends on context

Turkish shows some kinds of specificity in other ways, especially with the direct object. In this sentence, kursiyeri is clearly marked as a specific/complete object by the accusative ending.

Not exactly.

• kursiyer usually means course participant, trainee, or someone attending a course
• öğrenci is the broader word for student/learner

So kursiyer fits especially well if the setting is a course, training program, or certification class.

In a sentence about a training center, kursiyer is a very natural choice.

Yes. İlk yardım is the normal Turkish expression for first aid.

Word by word:

• ilk = first
• yardım = help / aid

Together, ilk yardım functions as one established phrase. You will see it very often in medical, safety, and training contexts:

• ilk yardım çantası = first aid kit
• ilk yardım eğitimi = first aid training
• ilk yardım kursu = first aid course

So in this sentence, ilk yardım should be understood as one unit.
