Türkçe öğrendikçe kendimi daha rahat hissediyorum.

Öğrendikçe comes from the verb öğrenmek (to learn) plus the suffix -dikçe / -dıkça / -dukça / -dükçe, which often means:

• as ...
• while ... increasingly
• the more ...

So Türkçe öğrendikçe means:

• as I learn Turkish
• the more I learn Turkish

It shows a gradual change happening over time.

Here Türkçe is a bare direct object, which is very common in Turkish when the object is general, non-specific, or used as a category.

So:

• Türkçe öğrenmek = to learn Turkish
• İngilizce konuşmak = to speak English

Using Türkçeyi would make the object more specific or definite. In many everyday sentences about learning a language, Turkish prefers the bare form:

• Türkçe öğreniyorum = natural
• Türkçeyi öğreniyorum = also possible, but more definite/emphatic, like I am learning the Turkish language or I am learning Turkish specifically

Kendimi is the reflexive pronoun kendim with the accusative ending -i.

It means myself.

In Turkish, with hissetmek (to feel), it is very common to say:

• kendimi iyi hissediyorum = I feel good
• kendimi kötü hissediyorum = I feel bad
• kendimi rahat hissediyorum = I feel comfortable / at ease

So even though English usually just says I feel comfortable, Turkish often says the equivalent of I feel myself comfortable.

That is why kendimi sounds natural here.

Because hissetmek in this pattern takes a direct object, not a dative object.

So Turkish says:

• kendimi rahat hissediyorum

not

• kendime rahat hissediyorum

Think of it as a fixed Turkish structure:

• kendini + adjective + hissetmek

Examples:

• Kendimi mutlu hissediyorum. = I feel happy.
• Kendimi yorgun hissediyorum. = I feel tired.
• Kendimi daha rahat hissediyorum. = I feel more comfortable.

Daha means more, and rahat means comfortable, relaxed, at ease.

So daha rahat means:

• more comfortable
• more at ease
• more relaxed

In this sentence, it suggests a change:

• before, the speaker felt less comfortable
• now, as their Turkish improves, they feel more comfortable

It does not have to be a very formal comparison. It often just means increasingly more at ease.

Hissediyorum is from hissetmek (to feel) and uses the present continuous ending -iyor.

Formally:

• hisset-
• -iyor
• -um = I

So:

• hissediyorum = I am feeling / I feel

In Turkish, the -iyor form is used not only for actions happening right now, but also for:

• ongoing situations
• current states
• things developing over time

That makes it a very natural choice here, because the speaker’s comfort is increasing during the process of learning Turkish.

It can suggest both, depending on context.

Öğrendikçe often carries the idea of a process with gradual change, so in English you could understand it as:

• As I learn Turkish, I feel more comfortable.
• The more Turkish I learn, the more comfortable I feel.

The second version brings out the progressive, increasing relationship more clearly, but both match the Turkish structure well.

Sometimes in casual speech people may say:

• Daha rahat hissediyorum.

and it can still be understood as I feel more comfortable.

But with hissetmek, including kendimi is often the more complete and natural pattern when talking about your own physical or emotional state:

• Kendimi iyi hissediyorum.
• Kendimi daha rahat hissediyorum.

So in this sentence, kendimi is very natural and idiomatic.

It breaks down like this:

• Türkçe = Turkish
• öğrendikçe = as I learn / the more I learn
• kendimi = myself
• daha rahat = more comfortable / more at ease
• hissediyorum = I feel

So the overall structure is:

• [As I learn Turkish] [I feel myself more comfortable].

More naturally in English:

• As I learn Turkish, I feel more comfortable.

The main verb comes at the end, which is very normal in Turkish.

Because Turkish often puts the context or subordinate clause first, and then ends with the main verb.

So this order is very natural:

• Türkçe öğrendikçe kendimi daha rahat hissediyorum.

It first sets up the condition/process:

• as I learn Turkish

and then gives the result:

• I feel more comfortable

This is a common Turkish sentence flow.

This is an important difference.

öğrendikçe

Means:

• as I learn
• the more I learn
• gradual, continuing process

öğrenince

Usually means:

• when I learn
• once I learn
• after that point happens

So:

• Türkçe öğrendikçe... = while my Turkish is improving, my comfort is increasing too
• Türkçe öğrenince... = when/once I learn Turkish, then I feel more comfortable

Your sentence uses öğrendikçe because it describes an ongoing change, not a single finished moment.

Yes. In Turkish, names of languages are capitalized:

• Türkçe
• İngilizce
• Fransızca

So writing Türkçe with a capital T is correct.

A couple of things may stand out to English speakers:

• ö is like the vowel in German schön or French peu, if you know those.
• ğ usually is not pronounced as a strong consonant in modern Turkish. It often lengthens or smooths the vowel before it.
• ç is pronounced like ch in church.

So öğrendikçe is pronounced roughly like:

• uh-ren-dik-che

That is only approximate, but it helps show that ç = ch, and ğ is soft.
