İlk yardım eğitimi temel yaşam desteğini içeriyor.

It is a noun compound, very common in Turkish.

• ilk yardım = first aid
• eğitim = training / education
• eğitimi = its training in compound form

So:

• ilk yardım eğitimi literally looks like first aid training-of
• but in natural English it simply means first aid training

In Turkish, when one noun modifies another noun, the second noun often takes a special ending. That is why you get eğitim → eğitimi.

So this is not saying the training of the first aid in a strange English sense; it is just the normal Turkish way to say first aid training.

Because it is the second part of a definite noun compound.

Pattern:

• X Y-si / -sı / -su / -sü or -i / -ı / -u / -ü

Examples:

• Türk kahvesi = Turkish coffee
• okul kapısı = school door
• ilk yardım eğitimi = first aid training

Here:

• eğitim ends up as eğitimi

This ending is not the same as the normal accusative ending here. It is part of the compound structure.

So:

• eğitim = training
• ilk yardım eğitimi = first aid training

Because this phrase is the direct object of the verb içeriyor and it is marked with the accusative.

First, the noun compound is:

• temel yaşam desteği = basic life support

Then, because it is the specific thing being included, it gets the accusative:

• temel yaşam desteği
  • accusative → temel yaşam desteğini

That extra -ni may look confusing, but it makes sense once you break it down:

• destek = support
• desteği = support (in compound form)
• desteğini = the basic life support as a specific object

This is a very common pattern with possessed/compound nouns.

Because desteği already has a possessive/compound ending, and Turkish usually inserts an n before some case endings in that situation.

So the pattern is:

• desteği
• desteği + (y)I would not sound right directly
• Turkish uses a buffer consonant: desteğini

You can think of it like this:

• base compound form: yaşam desteği
• accusative form: yaşam desteğini

This n is very normal after third-person possessive forms and compound nouns.

Here it means contains or includes.

Literally, içeriyor is the -iyor form, which is often taught as the present continuous:

• içeriyor = is including / is containing

But in real Turkish, this form is very often used for general present meaning too, especially in everyday speech.

So in this sentence:

• İlk yardım eğitimi temel yaşam desteğini içeriyor.
• Natural English: First aid training includes basic life support.

Not: is including in awkward English.

Yes.

• içerir = aorist/simple present; often more formal, general, factual
• içeriyor = very common in everyday Turkish, and can also express a general fact

So both can work:

• İlk yardım eğitimi temel yaşam desteğini içerir.
• İlk yardım eğitimi temel yaşam desteğini içeriyor.

The version with içeriyor sounds more conversational and natural in modern spoken Turkish.

Turkish normally puts the verb at the end.

English:

• First aid training includes basic life support.

Turkish:

• İlk yardım eğitimi = subject
• temel yaşam desteğini = object
• içeriyor = verb

So the structure is:

• Subject + Object + Verb

That is one of the biggest differences English speakers notice in Turkish.

A very useful clue is the ending.

• İlk yardım eğitimi has no object marking here, so it is the subject
• temel yaşam desteğini has the accusative ending, so it is the direct object
• içeriyor is the verb

So the sentence is:

• [Subject] İlk yardım eğitimi
• [Object] temel yaşam desteğini
• [Verb] içeriyor

Even if Turkish word order changes for emphasis, these endings help show the roles.

Literally:

• ilk = first
• yardım = help / aid

So ilk yardım = first aid

This is a fixed expression in Turkish, just like in English.
You should learn ilk yardım as a set phrase.

Word by word:

• temel = basic / fundamental
• yaşam = life / living
• destek = support
• desteği = support (compound form)

So:

• temel yaşam desteği = basic life support

This is also a set expression, especially in medical or training contexts.

A rough pronunciation is:

• ee-cheh-ree-yor

More carefully:

• i = like ee in see
• ç = ch
• e = like e in bed
• ri = a short ree
• yor = yor

So:

• içeriyor ≈ ee-che-ree-yor

Also note:

• ı in words like ilk is actually i, not ı
• Turkish spelling is generally very regular, so once you know the sounds, pronunciation becomes much easier.

Turkish does not have a word exactly like English the.

Whether something is understood as definite or specific is often shown by:

• context
• word order
• case endings, especially the accusative

Here, temel yaşam desteğini is marked as a specific object, which helps give a the/basic life support kind of meaning.

So Turkish does not need a separate article like English does.

You can do a rough literal breakdown, but it will sound unnatural in English.

Word by word:

• İlk yardım eğitimi = first aid training
• temel yaşam desteğini = basic life support-(accusative)
• içeriyor = includes / is containing

Natural English:

• First aid training includes basic life support.

A very literal gloss might be:

• First aid training basic life support includes.

That helps you see the Turkish structure, but it is not good English.
