Ne olursa olsun, ben bu projeden vazgeçmeyeceğim.

Yes. Ne olursa olsun is a very common fixed expression meaning no matter what or whatever happens.

A rough literal breakdown is:

• ne = what
• olursa = if it happens / if it becomes
• olsun = let it be

But in real Turkish, you should mostly learn ne olursa olsun as a set phrase meaning regardless of what happens.

By itself, ne usually means what. But in patterns like ne ... olursa olsun, it takes on the sense of whatever.

So:

• ne = what
• ne olursa olsun = whatever happens / no matter what

This is similar to how English what can become whatever in certain expressions.

You may also see related patterns such as:

• kim olursa olsun = whoever it is / no matter who it is
• nerede olursa olsun = wherever it is
• nasıl olursa olsun = no matter how

Because the expression is built from two different grammatical forms of olmak:

• olur-sa = if it happens / if it is
• ol-sun = let it be

So the structure is basically:

• ne olursa olsun = whatever happens, let it be

In modern Turkish, though, this is better understood as an idiomatic whole rather than something speakers consciously analyze every time.

Olursa comes from olmak and contains the conditional suffix -sa / -se.

Breakdown:

• olur = it happens / it becomes / it is
• olur-sa = if it happens / if it becomes

The -sa / -se suffix is the basic if or conditional ending in Turkish.

Examples:

• Gelirse, konuşuruz. = If he/she comes, we’ll talk.
• Vakit olursa, uğrarım. = If there is time, I’ll stop by.

So in ne olursa olsun, olursa gives the if/whatever may happen idea.

Olsun is a form of olmak often described as the 3rd person imperative or optative-like form.

It can mean things like:

• let it be
• may it be
• fine, let it happen

In this sentence, it is part of the set expression ne olursa olsun, so it does not feel like a direct command. It helps create the meaning no matter what.

You may also hear olsun in other common expressions:

• Tamam, olsun. = Okay, fine.
• Geç olsun, güç olmasın. = Better late than never.
  Literally: Let it be late, but not difficult.

No, ben is not grammatically necessary.

The verb vazgeçmeyeceğim already tells you the subject is I, because the ending -im / -ım / -um / -üm marks first person singular.

So both of these are correct:

• Ben bu projeden vazgeçmeyeceğim.
• Bu projeden vazgeçmeyeceğim.

Adding ben gives extra emphasis, like:

• I will not give up on this project.
• As for me, I won’t give up on this project.

So here ben adds determination or contrast.

Because the verb vazgeçmek takes the ablative case, usually -den / -dan / -ten / -tan.

So:

• bir şeyden vazgeçmek = to give up on something
• karardan vazgeçmek = to give up on a decision
• fikirden vazgeçmek = to abandon an idea

That is why we say:

• bu projeden vazgeçmek = to give up on this project

Not:

• bu projeyi vazgeçmek ❌

This is something you mostly need to memorize with the verb: vazgeçmek + ablative.

It breaks down like this:

• vazgeç- = give up
• -me- = negative
• -yecek- = future
• -im = I

So:

• vazgeçmek = to give up
• vazgeçmeyeceğim = I will not give up

A fuller breakdown:

• vazgeç = give up
• vazgeçme = not give up
• vazgeçmeyecek = will not give up
• vazgeçmeyeceğim = I will not give up

The y is a buffer consonant.

The negative suffix is -ma / -me, and the future suffix is -acak / -ecek. When these come together, Turkish often inserts y to make pronunciation smoother.

So:

• vazgeç-me-ecek-im would be awkward
• Turkish uses vazgeç-me-y-ecek-im

That is why you get:

• vazgeçmeyeceğim

This happens in many Turkish words when two vowels would otherwise meet.

Because of vowel harmony.

The future suffix has two main forms:

• -acak
• -ecek

Which one appears depends on the vowels before it. Since vazgeçme- contains front vowels (e), the front-vowel form -ecek is used:

• vazgeçmeyecek

If the word had back vowels, you would expect -acak instead.

Usually, yes, but its exact English translation depends on context. It can mean:

• to give up
• to quit
• to abandon
• to change one’s mind about continuing
• to refrain from

Examples:

• Sigarayı bıraktı = He quit smoking.
  But:

• Sigaradan vazgeçti = He gave up smoking.

• Bu plandan vazgeçtim. = I gave up on this plan.
• Gitmekten vazgeçtim. = I decided not to go / I gave up the idea of going.

So in your sentence, vazgeçmeyeceğim strongly conveys determination: I will not give up.

Yes. Turkish word order is flexible, though the emphasis changes.

The original:

• Ne olursa olsun, ben bu projeden vazgeçmeyeceğim.

This sounds natural and emphasizes the condition first: No matter what, I won’t give up on this project.

You could also say:

• Ben bu projeden vazgeçmeyeceğim, ne olursa olsun.

This puts the main statement first and adds ne olursa olsun afterward for dramatic emphasis, almost like I won’t give up on this project, no matter what.

Both are natural.

Because Ne olursa olsun functions as an introductory clause.

It sets the frame for the main statement:

• No matter what, ...
• Whatever happens, ...

So the comma helps separate that introductory expression from the main clause:

• Ne olursa olsun, ben bu projeden vazgeçmeyeceğim.

It is similar to English punctuation in sentences like:

• No matter what, I’m staying.
• Whatever happens, we’ll continue.
