Ο ενδυματολόγος μιλάει με τον βοηθό σκηνοθέτη.

Ο is the masculine singular definite article, equivalent to the.

So:

• ο ενδυματολόγος = the costume designer

In Greek, the definite article changes form depending on gender, number, and case.

Here, ο is used because ενδυματολόγος is:

• masculine
• singular
• in the nominative case (the subject of the sentence)

So Ο ενδυματολόγος is the person doing the action.

Because Greek articles change according to case.

• ο = masculine singular nominative
• τον = masculine singular accusative

In this sentence:

• ο ενδυματολόγος is the subject, so it takes the nominative
• με normally takes the accusative, so we get τον βοηθό

So:

• ο ενδυματολόγος = the costume designer
• με τον βοηθό = with the assistant

This is one of the big differences from English: English keeps the the same, but Greek changes the article form.

Yes, με usually takes the accusative case in Modern Greek.

So after με (with), a masculine singular noun typically appears with:

• τον
  • noun in the accusative

That is why we have:

• με τον βοηθό

A few more examples:

• με τον φίλο = with the friend
• με τον δάσκαλο = with the teacher
• με τον σκηνοθέτη = with the director

So με is a preposition that commonly triggers the accusative.

βοηθός σκηνοθέτη is a very natural Greek way to say assistant director.

Literally, it is something like:

• assistant of director

The word σκηνοθέτη is functioning like a genitive idea after βοηθός, even though in this set expression the article is often omitted.

So:

• βοηθός σκηνοθέτη = assistant director
• ο βοηθός του σκηνοθέτη more literally means the director’s assistant

Both can make sense, but they are not always felt the same way:

• βοηθός σκηνοθέτη sounds like a job title / role
• βοηθός του σκηνοθέτη can sound more like the assistant of the director

In your sentence, τον βοηθό σκηνοθέτη is the normal way to refer to the assistant director.

No. This is an important point.

Only βοηθό is directly after με and is in the accusative:

• με τον βοηθό

But σκηνοθέτη is tied to βοηθό, not directly to με.

The structure is:

• τον βοηθό σκηνοθέτη = the assistant director

So:

• βοηθό = accusative, because of με
• σκηνοθέτη = part of the noun phrase meaning director in the sense of assistant director

This can be confusing because σκηνοθέτη looks identical to other forms of the noun. Greek often has forms that look the same in different cases.

ενδυματολόγος is in the nominative singular.

That is because it is the subject of the sentence — the person who is doing the speaking.

The full subject is:

• Ο ενδυματολόγος

Greek subjects normally appear in the nominative.

Yes. μιλάει is the present tense, 3rd person singular, of μιλάω / μιλώ (to speak, to talk).

So μιλάει means:

• he/she speaks
• he/she is speaking
• he/she talks

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

So this sentence could mean:

• The costume designer speaks with the assistant director
• The costume designer is speaking with the assistant director

Both are possible unless the context makes one more natural.

Yes. You may also see:

• μιλάει
• μιλά

Both are common in Modern Greek and mean the same thing here.

So these are both fine:

• Ο ενδυματολόγος μιλάει με τον βοηθό σκηνοθέτη.
• Ο ενδυματολόγος μιλά με τον βοηθό σκηνοθέτη.

For learners, it is useful to recognize both spellings/forms.

A rough pronunciation guide is:

• en-dhee-ma-to-LO-ghos

Some details:

• νδ here is pronounced like nd
• υ in this word sounds like ee
• γ before ο is a soft voiced sound, often approximated for English speakers as a light gh
• the stress is on -λό-: ενδυματολόγος

A more broken-down version:

• εν = en
• δυ = dhee
• μα = ma
• το = to
• λό = LO
• γος = ghos

A rough guide:

• vo-ee-THO skee-no-THE-tee

Notes:

• β in Modern Greek sounds like v
• οι sounds like ee
• η also sounds like ee
• θ sounds like English th in think
• stress falls on:
  • βοηθό → final syllable
  • σκηνοθέτη → θέ

So:

• βοηθό = vo-ee-THO
• σκηνοθέτη = skee-no-THE-tee

Because in this kind of job-title expression, Greek often leaves out the second article.

So:

• βοηθός σκηνοθέτη = assistant director

This is a compact noun phrase. Greek does this quite naturally with professions and roles.

If you added the article, you would usually change the nuance or structure:

• ο βοηθός του σκηνοθέτη = the director’s assistant

That is grammatical, but it is not the same fixed title-like expression as βοηθός σκηνοθέτη.

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

The neutral order here is:

• Ο ενδυματολόγος μιλάει με τον βοηθό σκηνοθέτη.

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

• Με τον βοηθό σκηνοθέτη μιλάει ο ενδυματολόγος.
• Μιλάει με τον βοηθό σκηνοθέτη ο ενδυματολόγος.

These are not all equally neutral in every context, but they are possible.

English usually relies much more heavily on fixed word order.

Yes, μιλάω/μιλώ με κάποιον can mean either:

• speak with someone
• talk to someone

In natural English, we often translate it simply as:

• talks to the assistant director
• is talking with the assistant director

The exact English choice depends on context and style, not on a grammatical difference in the Greek sentence.

In this sentence, the article ο shows that the noun is being used as masculine.

So here it refers to a male costume designer.

If the person were female, Greek would normally use the feminine article and often a feminine noun form, depending on the word and common usage. For example, many profession nouns have feminine equivalents or a feminine article may be used according to modern usage patterns.

The key point for this sentence is:

• ο tells you the person is grammatically masculine

So yes, in this sentence the costume designer is presented as male.

The dictionary forms are the nominative singular forms:

• ενδυματολόγος = costume designer
• βοηθός = assistant
• σκηνοθέτης = director

In the sentence, not all of them appear in dictionary form:

• ενδυματολόγος → dictionary form
• βοηθό → accusative form of βοηθός
• σκηνοθέτη → related form of σκηνοθέτης in this expression

This is very useful when looking words up: if you see βοηθό, look for βοηθός in the dictionary.

These are just different noun patterns in Greek.

In this sentence:

• ενδυματολόγος ends in -ος
• βοηθός also ends in -ός
• σκηνοθέτης ends in -ης

All three are masculine nouns, but they belong to different declension patterns.

That means their case forms change in slightly different ways. For example:

• ο βοηθός → τον βοηθό
• ο σκηνοθέτης → τον σκηνοθέτη

So the ending helps tell you how the noun behaves grammatically.

Yes. Accent marks matter in Greek because they show which syllable is stressed.

For example:

• ενδυματολόγος
• μιλάει
• βοηθό
• σκηνοθέτη

If you ignore the accents, people will often still understand you in writing, but correct accents are important in standard Greek spelling and help with pronunciation.

They are especially useful for learners because Greek stress is phonemic — it really is part of the word.
