Çok şükür herkes iyi.

In Turkish, the verb to be is often not stated in the present tense, third person.

So:

• Herkes iyi. = Everyone is fine / well.
• Literally, it looks like Everyone fine.

This is completely normal Turkish.

The missing is/are idea is understood automatically.
If you change the tense, Turkish usually shows it more clearly:

• Herkes iyiydi. = Everyone was fine.
• Herkes iyi olacak. = Everyone will be fine.

So in your sentence, the present-tense to be is just invisible.

Çok şükür is a very common expression of relief or gratitude.

It is used when something turned out well, especially after worry or uncertainty.

Common English equivalents include:

• Thank goodness
• Thank God
• Thankfully
• I’m so relieved

Literally:

• çok = very / much
• şükür = thanks / gratitude

But as a full expression, it works idiomatically, not word-for-word.

In Çok şükür herkes iyi, it sets the emotional tone first: relief that everyone is okay.

It can sound religious, because şükür is connected with giving thanks, often to God. But in everyday Turkish, çok şükür is also widely used as a normal expression of relief, even in casual speech.

So depending on the speaker and context, it may feel:

• openly religious,
• mildly religious,
• or simply idiomatic and emotional.

A stronger and more explicitly religious version is:

• Allah’a şükür = Thanks be to God

Compared with that, çok şükür is often a bit broader and more everyday.

Turkish word order is flexible, especially with short expressions like çok şükür.

Here, çok şükür is placed first to highlight the speaker’s feeling of relief:

• Çok şükür herkes iyi.
  = Thank goodness, everyone is fine.

If you move it, the sentence still works:

• Herkes iyi, çok şükür.

That version may sound a little more like an afterthought: first the information, then the relief.

So the original order is natural because it foregrounds emotion.

Here iyi is an adjective used as a predicate, meaning something like:

• fine
• well
• okay
• good

In Turkish, iyi covers a range that English often splits into good and well.

So:

• Herkes iyi. = Everyone is fine / well.

Even though English often prefers well for health, Turkish simply uses iyi very naturally in this kind of sentence.

Herkes means everyone / everybody, and grammatically it behaves as a singular word in Turkish.

So if there were an explicit verb, it would normally be singular:

• Herkes geldi. = Everyone came.
• Herkes iyiydi. = Everyone was fine.

This is similar to English, where everyone is correct, not everyone are.

So herkes iyi is exactly what you would expect.

Yes. Herkes iyi. is a complete sentence.

Adding çok şükür adds the feeling of relief or gratitude:

• Herkes iyi. = neutral statement
• Çok şükür herkes iyi. = relieved / thankful statement

So the shorter version is perfectly natural if you just want to report the fact.

Yes. You may hear several natural versions:

• Çok şükür herkes iyi.
• Herkes iyi, çok şükür.
• Şükür, herkes iyi.

The meaning stays very similar, but the emphasis changes a bit.

• Sentence-initial çok şükür emphasizes relief first.
• Sentence-final çok şükür feels a little more like a concluding comment.

All are common in speech.

A simple pronunciation guide:

• ç = like ch in chair
• ş = like sh in shoe
• ü = a front rounded vowel not found in standard English; roughly like saying ee while rounding your lips
• ö does not appear here, but çok has o, a normal short o

Approximate pronunciation:

• Çok ≈ chok
• şükür ≈ shü-kür
• herkes ≈ her-kes
• iyi ≈ ee-yee

A rough full approximation:

• CHOK SHÜ-KÜR HER-kes EE-yee

Also note that iyi has two vowels in sequence, so do not reduce it to one syllable.

Yes. In everyday speech, people sometimes say simply:

• Şükür.

This can mean things like:

• Thank goodness.
• That’s a relief.

It is shorter and very natural in conversation.

So:

• Şükür, herkes iyi.
• Çok şükür, herkes iyi.

Both work, with çok şükür sounding a bit stronger.

Because this is not an object phrase. It is a subject + predicate sentence.

• herkes = the subject
• iyi = the predicate adjective

Turkish does not add a special case ending here just because iyi is the description of the subject.

Compare:

• Herkes iyi. = Everyone is fine.
• Herkesi gördüm. = I saw everyone.

In the second sentence, herkes becomes herkesi because it is the definite direct object. In your sentence, it is the subject, so no accusative ending is needed.

Yes, very natural.

It sounds like something someone might say after being asked about family, friends, or people affected by a problem:

• after an illness
• after an accident scare
• after bad news
• after travel
• after a stressful event

It is short, idiomatic, and common in spoken Turkish.

No. A word-for-word translation would sound unnatural and misleading.

Turkish expressions often do not map neatly onto English word-for-word, especially idiomatic ones like çok şükür.

A better approach is:

• understand çok şükür as one expression of relief/gratitude
• understand herkes iyi as a normal Turkish everyone is fine structure with no visible to be

So it is much better to learn the sentence in chunks:

• çok şükür = expression of relief
• herkes iyi = everyone is fine

That will help you sound more natural than trying to translate each word mechanically.
