Η βάρκα επιστρέφει στο λιμάνι.

A natural pronunciation is roughly:

ee VAR-ka e-pi-STRE-fi sto lee-MA-ni

A few useful pronunciation notes:

• Η is pronounced ee.
• β is pronounced v, not English b.
• ρ is a rolled or tapped r.
• στρ in επιστρέφει can feel tricky; say it slowly at first: e-pi-stre-fi.
• The stressed syllables are marked by the accent: βάρκα, επιστρέφει, λιμάνι.

Η is the feminine singular definite article, meaning the.

So:

• η βάρκα = the boat

The noun βάρκα is feminine, so it takes η in the nominative singular.

Greek often uses the definite article more regularly than English.

Here:

• η βάρκα = the boat
• βάρκα = a boat / boat, depending on context

If the English meaning shown to the learner is the boat returns to the harbor, then η βάρκα matches that exactly.

επιστρέφει is the 3rd person singular form of the verb επιστρέφω, meaning to return.

So επιστρέφει means:

• returns
• is returning

In Greek, the present tense often covers both the simple present and the present continuous, depending on context.

The ending -ει is a common present-tense ending for he/she/it in Modern Greek.

Here the subject is η βάρκα (the boat), which is grammatically she/it in form, so the verb is in 3rd person singular:

• επιστρέφω = I return
• επιστρέφεις = you return
• επιστρέφει = he/she/it returns

It can mean either one.

Greek present tense often works for both:

• The boat returns to the harbor
• The boat is returning to the harbor

Context tells you which sounds more natural in English.

στο is a contraction of:

• σε = to / in / at
• το = the

So:

• σε το → στο

In this sentence:

• στο λιμάνι = to the harbor

This contraction is extremely common in Modern Greek.

Because the sentence needs the idea to the harbor, not just the harbor.

• το λιμάνι = the harbor
• στο λιμάνι = to the harbor / in the harbor, depending on context

After a verb like επιστρέφει (returns), στο λιμάνι is understood as to the harbor.

It is in the accusative singular.

After σε (and therefore after στο), Greek uses the accusative:

• nominative: το λιμάνι
• accusative: το λιμάνι

In this particular noun, the nominative and accusative look the same, which is very common for neuter nouns.

You can tell from the article το inside στο.

Since:

• στο = σε + το

the noun that follows is neuter singular here:

• το λιμάνι = the harbor

So λιμάνι is a neuter noun.

Usually, grammatical gender in Greek is something you simply learn with each noun.

For these words:

• η βάρκα = feminine
• το λιμάνι = neuter

Sometimes endings give you clues:

• nouns ending in -α are often feminine, like βάρκα
• nouns ending in -ι are often neuter, like λιμάνι

But these are patterns, not absolute rules, so it is best to learn each noun together with its article.

The accent mark shows which syllable is stressed.

So:

• βάρκα → stress on βάρ-
• επιστρέφει → stress on -στρέ-
• λιμάνι → stress on -μά-

Stress matters in Greek pronunciation, and sometimes it can even help distinguish forms.

Yes, Greek word order is more flexible than English, although some orders sound more neutral than others.

The most neutral version here is:

• Η βάρκα επιστρέφει στο λιμάνι.

But you may also hear:

• Στο λιμάνι επιστρέφει η βάρκα.
• Επιστρέφει στο λιμάνι η βάρκα.

These alternatives can shift the emphasis, but the basic meaning stays the same.

επιστρέφει is a very good, standard verb for returns / is returning.

Another possible verb is γυρίζει, which can also mean returns / comes back / turns, depending on context.

But:

• Η βάρκα επιστρέφει στο λιμάνι sounds precise and standard for The boat returns to the harbor.

Greek often drops subject pronouns, but nouns are usually kept when you want to state clearly who or what is doing the action.

So:

• Επιστρέφει στο λιμάνι. = It/he/she is returning to the harbor.
• Η βάρκα επιστρέφει στο λιμάνι. = The boat is returning to the harbor.

Including η βάρκα makes the subject explicit.

In Modern Greek, the letter β is pronounced v.

So:

• βάρκα sounds like varka, not barka

If Greek wants a true b sound, it usually uses the combination μπ.

This is one of the first pronunciation differences English speakers need to get used to.
