Yani, karar kesin.

In this sentence, yani is a discourse word that can mean so, that is, in other words, or I mean, depending on context.

Here, it most naturally works like so or in other words:

• Yani, karar kesin.
• So, the decision is final.

It does not change the core grammar of the sentence very much; it mainly helps connect this sentence to what was said before.

Turkish often leaves out the verb to be in the present tense, especially in the third person.

So:

• karar kesin = the decision is final/certain

This is completely normal Turkish.

You may also see a more formal or emphatic version:

• Karar kesindir.

The ending -dir adds a more formal, assertive tone, but the basic meaning is very similar.

Karar means decision.

Depending on context, it can also mean things like judgment, ruling, or resolution, but decision is the most common meaning for learners to remember first.

In this sentence:

• karar = the decision

Turkish does not have a word like English the, so whether it means a decision or the decision depends on context. Here, it usually means the decision.

Kesin is an adjective. It can mean:

• certain
• definite
• final
• clear-cut

In karar kesin, the most natural English meanings are usually:

• The decision is final.
• The decision is definite.

So kesin does not only mean certain in the sense of sure; it can also mean something is settled or not open to change.

Yes.

In karar kesin:

• karar = the subject noun
• kesin = the predicate adjective

So the structure is basically:

• [subject] + [adjective]
• karar + kesin
• the decision + final

This is a very common Turkish pattern.

Yes, it is normal.

Turkish often puts the main predicate at the end of the sentence. Here, the predicate is the adjective kesin.

So:

• karar kesin

feels natural because Turkish often builds sentences so that the important conclusion comes at the end.

If you moved things around, it would usually sound less neutral or less standard.

Turkish does not have a definite article like English the.

So karar can mean:

• a decision
• the decision

The context tells you which one is meant.

In Yani, karar kesin, it usually means the decision, because the speaker is referring to a specific decision already being discussed.

The comma shows a pause after yani.

Since yani often works like so, well, or in other words, writers often separate it with a comma:

• Yani, karar kesin.

This helps show that yani is a sentence-opening connector, not part of the main clause itself.

In casual writing, punctuation may vary, but the comma is very natural here.

Yes, absolutely.

• Karar kesin. = The decision is final.
• Yani, karar kesin. = So / in other words, the decision is final.

Adding yani makes the sentence feel more connected to previous conversation. Without it, the sentence is more direct and standalone.

They are related, but they do different jobs.

• kesin = an adjective meaning certain, definite, final
• kesinlikle = an adverb meaning definitely, absolutely

So:

• Karar kesin. = The decision is final.
• Kesinlikle geliyorum. = I am definitely coming.

You cannot usually replace one directly with the other.

A simple pronunciation guide is:

• Yani ≈ YAH-nee
• karar ≈ kah-RAHR
• kesin ≈ keh-SEEN

So the whole sentence sounds roughly like:

• YAH-nee, kah-RAHR keh-SEEN

A few useful points:

• Turkish a is usually like a in father
• Turkish i is like ee in see
• The stress in kesin is usually on the second syllable: ke-SİN
