Το χρυσό βραχιόλι ταιριάζει με το κολιέ.

Because Greek uses the definite article with each noun phrase. In this sentence, το means the both times.

• το χρυσό βραχιόλι = the gold bracelet
• με το κολιέ = with the necklace

Both βραχιόλι and κολιέ are neuter singular nouns, so the article is το in both places.

Because χρυσό is an adjective, and Greek adjectives must agree with the noun they describe in gender, number, and case.

The basic forms are:

• masculine: χρυσός
• feminine: χρυσή
• neuter: χρυσό

Since βραχιόλι is neuter singular, the adjective must also be neuter singular: χρυσό.

Both are neuter.

You can see that from the article το. Also:

• many nouns ending in -ι are neuter, like βραχιόλι
• κολιέ is a loanword, and it is also treated as neuter

So both noun phrases use το.

Το χρυσό βραχιόλι is the subject, so it is in the nominative.

After με, Greek normally uses the accusative, so το κολιέ is accusative.

In this sentence, the forms do not visibly change much because:

• neuter singular το is the same in nominative and accusative
• βραχιόλι also looks the same in nominative and accusative singular
• κολιέ is indeclinable, so it stays the same anyway

Because the subject is singular: το χρυσό βραχιόλι.

Ταιριάζει is the 3rd person singular present form of ταιριάζω.

So:

• ταιριάζω = I match / fit / suit
• ταιριάζει = it matches / fits / suits

Since the subject is the bracelet, Greek uses the singular verb.

Here ταιριάζει με means goes with, matches, or looks good with.

It is commonly used for things like:

• clothes
• colors
• jewelry
• furniture
• styles

So the sentence means that the bracelet and the necklace go well together.

Very often, yes. In this sentence, με means with:

• με το κολιέ = with the necklace

More generally, με can also have meanings like using, by means of, or together with, depending on the context.

Because κολιέ is an indeclinable noun. That means it keeps the same form in different grammatical roles.

So you may see:

• το κολιέ
• με το κολιέ
• στο κολιέ

The noun itself stays κολιέ, while the article or preposition helps show its function.

Yes. A very common Greek pattern is:

article + adjective + noun

So:

• το χρυσό βραχιόλι = the gold bracelet
• το όμορφο σπίτι = the beautiful house

That is the most neutral and standard order here.

Yes. Greek word order is more flexible than English.

The neutral order is:

Το χρυσό βραχιόλι ταιριάζει με το κολιέ.

But Greek can move parts of the sentence around for emphasis. For example, με το κολιέ could come earlier if you want to highlight the necklace. The original version is the most natural basic sentence.

They show which syllable is stressed.

• χρυσό
• βραχιόλι
• ταιριάζει
• κολιέ

Stress matters in Greek pronunciation, so the accent marks are important. One useful extra point is that αι in ταιριάζει is pronounced like e.

It can mean either, depending on context.

So χρυσό βραχιόλι can mean:

• a bracelet made of gold
• a golden-colored bracelet

Usually the situation makes it clear. If someone wants to be especially explicit about the material, Greek can also use forms like χρυσένιο.
