Ο ηθοποιός αποστηθίζει την ατάκα.

Ο is the masculine singular definite article in the nominative case. In English, it usually corresponds to the.

So:

• ο ηθοποιός = the actor

Here, ηθοποιός is the subject of the sentence, so it appears in the nominative, and the article matches it in gender, number, and case.

Because ατάκα is the direct object of the verb, not the subject.

Greek changes the article depending on the noun’s role in the sentence:

• η ατάκα = the line as a subject
• την ατάκα = the line as a direct object

In this sentence:

• ο ηθοποιός = the subject
• την ατάκα = the thing being memorized, so it is in the accusative case

That is why Greek uses την, the feminine singular accusative form of the definite article.

αποστηθίζει is:

• 3rd person singular
• present tense
• active voice

It means he/she memorizes or is memorizing, depending on context.

The dictionary form is:

• αποστηθίζω = to memorize / to learn by heart

So the pattern is:

• εγώ αποστηθίζω = I memorize
• εσύ αποστηθίζεις = you memorize
• αυτός/αυτή αποστηθίζει = he/she memorizes

Since the subject is ο ηθοποιός (the actor), the verb correctly appears in the 3rd person singular.

Ατάκα often means a line in speech, especially:

• a line in a play
• a line in a film
• a short spoken bit of dialogue

Depending on context, it can also mean a remark, quip, or one-liner.

In this sentence, with ηθοποιός (actor), the most natural meaning is:

• the actor memorizes the line

So this is probably about an actor learning a spoken line from a script.

Yes, αποστηθίζω is a real and common Greek verb meaning:

• to memorize
• to learn by heart
• sometimes to memorize by rote

It can sound a little more like commit to memory thoroughly, sometimes even with the nuance of rote learning.

Another common expression is:

• μαθαίνω απ’ έξω = learn by heart / memorize

So depending on context, Greek speakers might say either of these.

It is pronounced roughly like:

• ee-tho-pyós

A few helpful points:

• η sounds like ee
• θ sounds like th in think
• οι is pronounced like ee in Modern Greek
• the stress is on the last syllable: -ός

So:

• ηθοποιός → ee-tho-pyós

The combination ποι here sounds roughly like pyi / pi depending on how carefully it is pronounced.

In this sentence, ηθοποιός is masculine because of the article ο, but the noun itself is a bit interesting.

ηθοποιός can refer to:

• a male actor with ο ηθοποιός
• a female actor/actress with η ηθοποιός

So it is one of those nouns whose form stays the same, while the article shows the gender.

Examples:

• ο ηθοποιός = the male actor
• η ηθοποιός = the female actor / actress

That means the article is especially important here.

Because Greek often omits subject pronouns when they are not needed.

The verb ending already tells you the person and number:

• αποστηθίζει = he/she memorizes

Since the sentence also includes the noun ο ηθοποιός, it is completely clear who is doing the action, so Greek does not need a separate pronoun like he.

A literal English-style version with a pronoun would be unnecessary in Greek.

Yes. Greek word order is often more flexible than English because case endings and articles help show what each noun is doing.

The neutral, straightforward order here is:

• Ο ηθοποιός αποστηθίζει την ατάκα.

But other orders are possible, depending on emphasis, for example:

• Την ατάκα αποστηθίζει ο ηθοποιός.
• Αποστηθίζει την ατάκα ο ηθοποιός.

These can sound more marked or stylistically different, but they are still understandable because:

• ο ηθοποιός is nominative
• την ατάκα is accusative

So Greek does not rely on word order as strictly as English does.

In Modern Greek, the final -ν in words like την is often kept before:

• vowels
• κ, π, τ
• γκ, μπ, ντ, τσ, τζ
• sometimes other consonants depending on speech style

Since ατάκα begins with a vowel (α), the -ν is definitely kept:

• την ατάκα

You may also notice this in other examples:

• τον άνθρωπο
• την εποχή

So in this sentence, την is exactly what you would expect.

Two main cases appear here:

1. Nominative for the subject

   • ο ηθοποιός

2. Accusative for the direct object

   • την ατάκα

This is one of the most basic Greek sentence patterns:

• subject (nominative) + verb + object (accusative)

So the sentence is a very useful example of how Greek marks grammatical roles not just by word order, but also by articles and case forms.

The stress marks show which syllable is emphasized:

• ηθοποιός → stress on the last syllable
• αποστηθίζει → stress on θί
• ατάκα → stress on τά

Stress matters in Greek, both for pronunciation and for correct spelling. You should learn each new word together with its stress.

So it helps to remember them as:

• ηθοποιός
• αποστηθίζει
• ατάκα

Yes. The Greek present tense often covers both:

• The actor memorizes the line
• The actor is memorizing the line

Greek does not always separate simple present and present continuous the way English does. The exact best translation depends on context.

So without more context, αποστηθίζει can describe either:

• a general action/habit
• an action happening now

English forces you to choose more specifically, but Greek often leaves that to context.
