Το εσωτερικό έχει δύο καθίσματα.

Το εσωτερικό is the subject of the sentence. It means the interior or the inside.

• το = the for a neuter singular noun
• εσωτερικό = interior / inside

So Greek is saying The interior has...

Εσωτερικό is a neuter singular form. In this sentence, it is being used like a noun meaning interior.

It originally comes from an adjective meaning interior / internal, but Greek often uses adjectives as nouns when the meaning is clear.

So το εσωτερικό literally means something like the interior part or simply the interior.

Greek uses a definite article much more regularly than English in many contexts.

Here, το means the and it agrees with εσωτερικό:

• το = neuter singular article
• εσωτερικό = neuter singular noun/adjectival noun

So they match in gender, number, and case.

Έχει is the 3rd person singular present tense of έχω, which means to have.

So:

• έχω = I have
• έχεις = you have
• έχει = he/she/it has

Because το εσωτερικό is singular, Greek uses έχει = has.

Because the subject is singular.

• το εσωτερικό = singular
• so the verb must also be singular: έχει

If the subject were plural, you would use έχουν:

• Τα αυτοκίνητα έχουν δύο καθίσματα.
• The cars have two seats.

Δύο means two.

A useful thing to know is that δύο does not change form here. It stays δύο regardless of gender:

• δύο καθίσματα = two seats
• δύο πόρτες = two doors
• δύο αυτοκίνητα = two cars

So it is much simpler than adjectives, which usually have to agree with the noun.

Καθίσματα is plural because it follows δύο = two.

Its singular is κάθισμα:

• το κάθισμα = the seat
• τα καθίσματα = the seats

So:

• δύο καθίσματα = two seats

This is a neuter noun.

Because Greek does not use an indefinite article like English a/an in the same way.

In English you might think of has two seats, not has the two seats. Greek simply says:

• έχει δύο καθίσματα

If Greek wanted to mean the two seats, it could say:

• έχει τα δύο καθίσματα

But in your sentence, it just means has two seats.

It is in the accusative, because it is the direct object of έχει.

The sentence structure is:

• Το εσωτερικό = subject
• έχει = verb
• δύο καθίσματα = direct object

For many neuter nouns, the nominative and accusative forms are the same, so καθίσματα looks the same in both.

The given word order is the most neutral and natural:

• Το εσωτερικό έχει δύο καθίσματα.

Greek word order is fairly flexible, though, because endings and articles help show what each word is doing.

For emphasis, you might also hear:

• Δύο καθίσματα έχει το εσωτερικό.

That sounds more like It’s two seats that the interior has or The interior has two seats with emphasis on two seats.

So the original order is the best basic pattern to learn.

Greek uses an accent mark to show which syllable is stressed.

So:

• εσωτερικό → stress on the last syllable
• δύο → stress on the first syllable
• καθίσματα → stress on the first syllable

These accents are very important in written Greek because they show pronunciation and sometimes help distinguish forms.

A rough guide is:

To esoterikó éhi dýo kathísmata.

A few pronunciation notes:

• θ in καθίσματα sounds like th in think
• χ in έχει is a throat sound, like the h in some pronunciations of Bach or the Spanish j, but softer before i/e
• αι is pronounced like e in bet
• ει is pronounced like ee

So έχει sounds roughly like EH-hee, though the h-like sound is not exactly an English h.

Yes. Εσωτερικό can have several related meanings depending on context, such as:

• interior
• inside
• sometimes even domestic/internal in other expressions

But in a sentence like this one, especially about a vehicle or object, το εσωτερικό most naturally means the interior.
