Her istem koruma kapsamını belirliyor.

Her means every or each.

In Turkish, after her, the noun is normally singular, not plural. So:

• her istem = each/every request/claim
• not her istemler

This is very natural in Turkish and matches patterns like:

• her gün = every day
• her öğrenci = every student

So the singular istem is exactly what you should expect.

Here, istem is a noun.

It is related to the verb istemek (to want, to ask for, to request), but in this sentence istem is not functioning as a verb at all. It is the subject noun of the sentence.

Depending on context, istem can be a technical or formal word, often meaning something like request or claim.

Koruma is a noun, meaning protection.

It comes from the verb korumak (to protect), but here it is being used as a noun. Turkish very often forms nouns like this from verbs.

So in this sentence:

• koruma = protection

It is not a verb like protecting in the sense of an action happening right now; it is simply the noun used inside a noun phrase.

This is a very common Turkish structure: a noun compound.

In Turkish, English X of Y is often expressed by putting two nouns together:

• first noun: the thing modifying
• second noun: the main noun, usually with a special ending

So:

• koruma kapsamı
• literally something like protection scope
• naturally understood as scope of protection

This is called an indefinite noun compound. The second noun takes the 3rd person possessive ending:

• kapsam = scope
• kapsamı = scope-of / its scope

In this kind of compound, that possessive ending does not always translate as a real its in English. It is just part of the normal Turkish structure.

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

Break it down like this:

• kapsam = scope
• kapsam-ı = scope + compound/possessive ending
• kapsam-ı-nı = scope + compound/possessive ending + accusative

So:

• koruma kapsamı = scope of protection
• koruma kapsamını = the scope of protection, as the direct object

The -n- is a buffer consonant. Turkish inserts it when an accusative ending is added after a possessive ending.

So this is a very useful pattern to recognize:

• possessive ending + accusative
• -sı / -si / -su / -sü → -sını / -sini / -sunu / -sünü
• or more generally ...ı + nı, ...i + ni, etc.

Because Turkish usually leaves the subject in the unmarked nominative form, while a specific direct object often takes the accusative.

In this sentence:

• Her istem = subject
• koruma kapsamını = direct object
• belirliyor = verb

So:

• the subject has no special ending
• the object is marked because it is treated as a specific object

This is very normal Turkish sentence structure.

The dictionary form is belirlemek (to determine).

To make belirliyor, Turkish does this:

• take the stem: belirle-
• add the present continuous suffix: -iyor

But when a verb stem ends in a vowel, that final vowel often drops before -iyor:

• belirle- + -iyor → belirliyor

So the form looks a little compressed, but it is completely regular.

You can compare it with:

• anla- → anlıyor
• başla- → başlıyor
• söyle- → söylüyor

Belirliyor is the present continuous form.

Literally, -iyor is the ending used for actions that are ongoing, like is determining. But in real Turkish, this form is also often used for:

• current processes
• habitual behavior
• explanations of how something works
• general statements in context

So here it does not have to mean only right now at this moment. It can also describe a general rule or function.

Yes, belirler is also possible in many contexts, but the nuance is a little different.

• belirliyor often sounds like a current, descriptive statement about how something functions
• belirler sounds more like a general rule, principle, or a more neutral/timeless statement

So both can work, but they do not feel exactly the same.

Very roughly:

• belirliyor = is determining / determines
• belirler = determines / will determine / generally determines

In explanatory or technical prose, both forms may appear depending on style.

The basic order is Subject – Object – Verb, which is very common in Turkish.

So here:

• Her istem = subject
• koruma kapsamını = object
• belirliyor = verb

That gives:

• Her istem koruma kapsamını belirliyor.

Turkish word order is flexible, so parts of the sentence can move for emphasis or topic marking, but the verb often stays near the end. This sentence uses a very standard, learner-friendly order.
