Η θαλασσοταραχή συνεχίζεται.

Η is the feminine singular definite article, so it means the.

It matches θαλασσοταραχή, which is a feminine singular noun. In dictionary form, the noun is η θαλασσοταραχή.

So:

• η = the
• θαλασσοταραχή = a feminine singular noun
• together: η θαλασσοταραχή = the rough sea / the sea turbulence / the stormy sea conditions depending on context

Because Greek often forms compounds as a single word.

θαλασσοταραχή is built from:

• θάλασσα = sea
• ταραχή = disturbance, turbulence, agitation

So the compound literally suggests something like sea-disturbance. In natural English, that may be translated as rough sea, sea turbulence, or stormy sea conditions, depending on context.

The -ο- in the middle is a common linking vowel in Greek compounds:

• θαλασσ-ο-ταραχή

A rough pronunciation guide is:

ee tha-lah-so-ta-ra-KHEE si-ne-KHEE-ze-te

A few useful notes:

• Η is pronounced ee
• χ is a rough sound, like the ch in German Bach or Scottish loch
• ή at the end of θαλασσοταραχή is the stressed syllable
• συνεχίζεται is stressed on χί

So the stress pattern is:

• θαλασσοταραχή
• συνεχίζεται

συνεχίζεται is:

• present tense
• 3rd person singular
• middle/passive form

It comes from the verb συνεχίζομαι / συνεχίζεται in this kind of use, meaning continues or is continuing.

So grammatically it means:

• it continues
• it is continuing

Since the subject is η θαλασσοταραχή, the full sentence means:

• The rough sea continues
• or more naturally, depending on context, The rough sea persists

That is a very common learner question.

In Greek, some verbs are often used in middle/passive forms even when English uses a simple active translation. συνεχίζεται is one of those forms in many contexts.

So although it looks passive to an English speaker, it often translates naturally as:

• continues
• goes on
• persists

Greek does not always match English voice in a one-to-one way. A form that looks “passive” may simply be the normal idiomatic way to express the idea.

Usually, όχι—not in this meaning.

συνεχίζει is the active form and normally needs an object, like continues something.

For example:

• Η εταιρεία συνεχίζει το πρόγραμμα. = The company continues the program.

But when the subject itself is what keeps going, Greek commonly uses:

• συνεχίζεται

So:

• Η θαλασσοταραχή συνεχίζεται = The rough sea continues / persists

That is the natural choice here.

Yes. The ending -ή is very often associated with feminine nouns in Greek.

So when you see θαλασσοταραχή, it is not surprising that it takes:

• the feminine article η

Also, in this sentence it is in the nominative singular, because it is the subject of the verb.

So the structure is:

• Η θαλασσοταραχή = the subject
• συνεχίζεται = the verb

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

The neutral, straightforward order is:

• Η θαλασσοταραχή συνεχίζεται.

But Greek can change word order for emphasis or style, for example:

• Συνεχίζεται η θαλασσοταραχή.

This still means the same thing, but it may sound a bit more like a report, announcement, or headline style: The rough sea continues / Rough sea conditions continue.

So both are possible, but the version you were given is the most basic subject-verb order.

In Modern Greek spelling, each content word normally shows the stressed syllable with an accent mark.

So:

• θαλασσοταραχή
• συνεχίζεται

But the article η is unstressed here, so it does not take an accent.

That is normal. Greek accents are mainly there to show pronunciation stress.

Yes, especially in contexts like:

• weather reports
• ferry announcements
• coast guard notices
• news reports

A very natural English rendering in those contexts might be:

• Rough sea conditions continue.
• The rough sea continues.
• Sea turbulence persists.

So while the exact English translation may vary, the Greek sentence is perfectly natural in formal or informational contexts.

In a full normal sentence like this, the article is usually expected:

• Η θαλασσοταραχή συνεχίζεται.

If you remove it:

• Θαλασσοταραχή συνεχίζεται

that can sound more like a headline, notice, or very compressed style, rather than ordinary full-sentence Greek.

So for standard everyday grammar, keep the article:

• Η θαλασσοταραχή συνεχίζεται.
