Sen gerçekten her şeyi bilmek istemiyor musun?

A natural breakdown is:

• Sen = you
• gerçekten = really / truly
• her şeyi = everything
• bilmek = to know
• istemiyor musun = don’t you want?

So the structure is roughly:

• You really everything to know don’t-want Q?

More naturally in English word order:

• Don’t you really want to know everything?

Turkish often puts the main finite verb part at the end, so long verb phrases like bilmek istemiyor musun naturally come last.

That is true. Turkish often leaves out subject pronouns because the verb already shows the person.

Here, musun tells you the subject is you (singular), so sen is not grammatically necessary.

• Gerçekten her şeyi bilmek istemiyor musun? = perfectly normal
• Sen gerçekten her şeyi bilmek istemiyor musun? = also correct, but more emphatic

Adding sen can:

• emphasize you
• create contrast, like you, of all people
• make the question sound more direct

So sen is there for emphasis, not because Turkish requires it.

Because her şeyi is the direct object of bilmek, and it is definite/specific.

• her şey = everything / every thing
• her şeyi = everything as a definite object, with the accusative ending

In Turkish, definite direct objects usually take the accusative ending.

Examples:

• Her şey güzel. = Everything is beautiful.
  Here her şey is the subject, so no accusative.

• Her şeyi biliyor. = He/She knows everything.
  Here her şeyi is the object, so it takes the accusative.

So in this sentence, her şeyi is correct because it is the thing being known.

After istemek (to want), Turkish usually uses the bare infinitive in -mek / -mak.

So:

• bilmek istemek = to want to know
• gitmek istemek = to want to go
• yapmak istemek = to want to do

That is the most normal pattern.

A form like bilmeyi istemek is possible in some contexts, but it feels more nominal, more like to want the act of knowing, and it is less natural here.

So bilmek istemiyor musun? is the normal everyday way to say don’t you want to know?

It can be understood as:

• iste- = want
• negative element = not
• -yor = present/imperfective marker
• mu = yes/no question particle
• -sun = you (singular)

So the whole thing means:

• are you not wanting?
• more natural English: don’t you want?

A learner-friendly way to think of it is:

• istemiyor = doesn’t want / is not wanting
• musun = do you? / are you? in question form for you

Together:

• istemiyor musun? = don’t you want?

Because the Turkish yes/no question particle mi / mı / mu / mü is written separately from the word before it.

So:

• geliyor musun? = are you coming?
• biliyor mu? = does he/she know?
• istemiyor musun? = don’t you want?

The personal ending often attaches to the question particle:

• mu + sun → musun

That is why you see:

• istemiyor musun not
• istemiyormusun

In standard Turkish spelling, the question particle is separate.

Not always in a strict English -ing sense.

In Turkish, -yor is very commonly used for the present, and it often covers both:

• is doing
• does

So:

• istiyor can mean is wanting or, more naturally, wants
• istemiyor can mean isn’t wanting or, more naturally, doesn’t want

In English, want is usually not phrased as a continuous action, so the best translation is normally:

• istemiyor musun? = don’t you want?

Even though Turkish uses -yor, the natural English result is usually simple present.

Gerçekten adds emphasis like:

• really
• truly
• sometimes actually

In this sentence, it most naturally means really:

• Sen gerçekten her şeyi bilmek istemiyor musun?
• Don’t you really want to know everything?

Depending on tone, it can express:

• genuine surprise
• disbelief
• insistence
• mild challenge

So it is not just factual; it can also color the speaker’s attitude.

Yes. Turkish word order is flexible, although some versions sound more neutral than others.

For example:

• Sen gerçekten her şeyi bilmek istemiyor musun?
• Gerçekten her şeyi bilmek istemiyor musun?
• Her şeyi gerçekten bilmek istemiyor musun?

All of these can work, but the emphasis shifts.

Very roughly:

• Sen... emphasizes you
• gerçekten... emphasizes really
• her şeyi... emphasizes everything

The verb phrase still usually stays near the end.

It can be either, depending on context and intonation.

Possible tones include:

• a real question: Are you sure you don’t want to know everything?
• surprise: You really don’t want to know everything?
• challenge or teasing: Come on, don’t you really want to know everything?

The negative question form often carries some expectation or emotional coloring, especially in speech.

So grammar alone does not fix the tone; intonation and context matter a lot.

This is a very common point of confusion for English speakers.

If someone asks:

• Sen gerçekten her şeyi bilmek istemiyor musun?

then:

• Evet, istemiyorum. = Yes, I don’t want to.
• Hayır, istiyorum. = No, I do want to.

So evet confirms the negative statement, and hayır rejects it.

This can feel backwards to English speakers, because English negative questions are often answered less systematically in everyday speech.

A safe strategy in Turkish is to answer with the full verb too:

• Evet, istemiyorum.
• Hayır, istiyorum.

That makes your meaning completely clear.
