Το γκρι πουλόβερ ταιριάζει με το μαύρο παλτό.

Because Greek uses the definite article with each noun phrase.

• το γκρι πουλόβερ = the grey sweater
• το μαύρο παλτό = the black coat

Unlike English, Greek normally repeats the article before each separate noun phrase. You do not use one the for both.

Also, both πουλόβερ and παλτό are neuter singular, so the article is το in both cases.

In Greek, every noun has a grammatical gender: masculine, feminine, or neuter. These two nouns are simply learned as neuter nouns:

• το πουλόβερ = the sweater
• το παλτό = the coat

Grammatical gender does not always match biological sex or anything logical in English. With clothing items especially, you just have to learn the noun together with its article.

A good habit is to memorize nouns like this:

• το πουλόβερ
• το παλτό

not just πουλόβερ or παλτό by themselves.

Because μαύρο is a regular adjective that changes form to agree with the noun, while γκρι is usually treated as an indeclinable color word, so it often stays the same.

Here:

• μαύρο matches the neuter singular noun παλτό
• γκρι stays γκρι, regardless of gender or number in many everyday uses

So:

• το μαύρο παλτό
• το γκρι πουλόβερ

This is very common with some color words, especially ones borrowed or used in a more fixed modern form, such as μπεζ, γκρι, and sometimes others.

Μαύρο is the neuter singular form of the adjective μαύρος = black.

The adjective changes to match the noun’s gender, number, and case. Common basic forms are:

• μαύρος = masculine
• μαύρη = feminine
• μαύρο = neuter

Since παλτό is neuter singular, the adjective must also be neuter singular:

• το μαύρο παλτό

Here ταιριάζει means matches, goes with, or suits.

In clothing contexts, ταιριάζει με is commonly used for things that look good together:

• Το γκρι πουλόβερ ταιριάζει με το μαύρο παλτό. = The grey sweater goes with the black coat.

It can also be used in other situations, for example:

• for colors that match
• for people who are well-suited to each other
• for something that is appropriate or fitting

Because the subject is third person singular:

• Το γκρι πουλόβερ = the grey sweater

So the verb must also be third person singular:

• ταιριάζω = I match / suit
• ταιριάζεις = you match / suit
• ταιριάζει = he/she/it matches, goes with, suits

Since the sweater is a singular thing, Greek uses ταιριάζει = it matches / it goes with.

Με means with.

The expression ταιριάζει με means matches with / goes with:

• ταιριάζει με το μαύρο παλτό = goes with the black coat

So in this sentence:

• the sweater is the subject
• με το μαύρο παλτό tells you what it matches with

After με, Greek uses the accusative.

So:

• το μαύρο παλτό here is in the accusative

However, for neuter singular nouns like παλτό, the nominative and accusative often look exactly the same. So even though it is accusative after με, you do not see a form change here.

This is one reason Greek learners sometimes do not notice case at first: the article and noun may look identical in different cases, especially in the neuter.

You know mainly from the structure and meaning:

• Το γκρι πουλόβερ comes before the verb and acts as the thing doing the matching
• με το μαύρο παλτό is a prepositional phrase introduced by με = with

So the sentence structure is:

• Subject: το γκρι πουλόβερ
• Verb: ταιριάζει
• Prepositional phrase: με το μαύρο παλτό

In English, this is similar to:

• The grey sweater goes with the black coat

Yes, Greek word order is more flexible than English word order.

The neutral, natural order here is:

• Το γκρι πουλόβερ ταιριάζει με το μαύρο παλτό.

But Greek can move things around for emphasis, for example:

• Με το μαύρο παλτό ταιριάζει το γκρι πουλόβερ.

That might emphasize with the black coat.

Even so, the original version is the most straightforward one for a learner and sounds very natural.

You can omit the articles in some contexts, but the meaning changes slightly.

• Το γκρι πουλόβερ ταιριάζει με το μαύρο παλτό. = The grey sweater goes with the black coat.

Without articles:

• Γκρι πουλόβερ ταιριάζει με μαύρο παλτό.

This sounds more general, like talking about clothing combinations in general rather than two specific items. In many everyday sentences about specific objects, Greek prefers the articles.

It is a loanword, originally from pullover. Greek has borrowed many clothing terms from other languages.

A useful thing for learners is that πουλόβερ is often treated as indeclinable in everyday use, meaning the noun itself usually does not change form much. The article helps show gender, number, and case:

• το πουλόβερ
• του πουλόβερ
• τα πουλόβερ

So even if the noun stays the same, the surrounding words still give grammatical information.

A simple learner-friendly pronunciation guide is:

To gri pou-LO-ver te-ri-A-zi me to MAV-ro pal-TO

A few notes:

• γρ in γκρι sounds like gr in grey
• πουλόβερ has stress on -λό-
• ταιριάζει has stress on -ά-
• μαύρο has stress on μαύ-
• παλτό has stress on the final -τό

If you want to sound more natural, pay attention to the stressed syllables, because stress is very important in Greek.

Sometimes yes, depending on context, but here matches / goes with is the right meaning.

Greek ταιριάζω can mean things like:

• match
• go well with
• suit
• be appropriate
• sometimes fit in a broader sense

But for clothes in the sense of size, Greek often uses other expressions too, depending on what exactly you mean. In this sentence, because of με and the two clothing items, the meaning is clearly matches with rather than fits in size.

Word by word, it is:

• Το = the
• γκρι = grey
• πουλόβερ = sweater / pullover
• ταιριάζει = matches / goes well
• με = with
• το = the
• μαύρο = black
• παλτό = coat

So a very literal version is:

The grey sweater matches with the black coat.

Natural English would usually be:

The grey sweater goes with the black coat.
