Αύριο έχουμε πρωινή σύσκεψη στο γραφείο, και η παρουσία μας είναι υποχρεωτική.

In Greek, έχω is often used the same way English uses have for scheduled events:

• Έχουμε σύσκεψη = We have a meeting
• Έχουμε μάθημα = We have class
• Έχουμε δουλειά = We have work

So Αύριο έχουμε πρωινή σύσκεψη naturally means Tomorrow we have a morning meeting. It does not imply possession in the strict sense; it means an event is scheduled for us.

Greek often uses the present tense for planned or scheduled future events, especially when a time word makes the future clear.

So:

• Αύριο έχουμε σύσκεψη = Tomorrow we have a meeting
• Το βράδυ φεύγω = I’m leaving tonight

This is very similar to English, where you can say Tomorrow we have a meeting instead of Tomorrow we will have a meeting.

Αύριο means tomorrow. It is an adverb of time.

It often comes at the beginning of the sentence because Greek commonly places time expressions early to set the scene:

• Αύριο έχουμε πρωινή σύσκεψη
• Σήμερα δουλεύω από το σπίτι
• Τη Δευτέρα φεύγουμε

However, other word orders are also possible depending on emphasis.

Because the adjective must agree with the noun in gender, number, and case.

Here:

• σύσκεψη = feminine singular noun
• so the adjective must also be feminine singular
• πρωινός = masculine
• πρωινή = feminine
• πρωινό = neuter

So:

• πρωινή σύσκεψη = morning meeting

This is standard adjective agreement in Greek.

Greek often leaves out the article when introducing something in a general or indefinite way.

So:

• έχουμε πρωινή σύσκεψη = we have a morning meeting

If you said μια πρωινή σύσκεψη, it would sound more like a certain morning meeting / one morning meeting, with a slightly more explicit indefinite sense.

If you said την πρωινή σύσκεψη, that would mean the morning meeting, referring to a specific meeting already known in context.

Σύσκεψη usually means a meeting, especially a work meeting, conference, or discussion session with a formal or organizational tone.

It is a common word in office and professional contexts. In casual contexts, other words may also appear, depending on the situation.

So in this sentence, σύσκεψη fits very naturally because the sentence also mentions στο γραφείο and η παρουσία μας είναι υποχρεωτική.

Στο is a contraction of:

• σε = in / at / to
• το = the (neuter singular accusative)

So:

• σε + το = στο

Therefore:

• στο γραφείο = at the office / in the office

This contraction is extremely common in Greek.

Γραφείο is a neuter noun meaning office.

After σε, nouns usually appear in the form that matches the accusative in Modern Greek. So:

• nominative: το γραφείο
• accusative: το γραφείο

For this noun, the nominative and accusative look the same, so nothing changes visibly.

That is why:

• στο γραφείο = in/at the office

Greek often uses more formal noun-based expressions, especially in workplace or official language.

• η παρουσία μας είναι υποχρεωτική literally means our presence is mandatory
• πρέπει να είμαστε εκεί means we must be there

Both are possible, but the version with παρουσία sounds more formal, official, and impersonal, which fits a workplace announcement.

Here μας means our.

Greek often uses the weak genitive pronoun after the noun to express possession:

• η παρουσία μας = our presence
• το γραφείο μου = my office
• ο φίλος της = her friend
• το σπίτι τους = their house

So Greek frequently says the equivalent of the presence of us, which is how it expresses our presence.

Because υποχρεωτική describes η παρουσία, and παρουσία is feminine singular.

Again, the adjective must agree with the noun:

• υποχρεωτικός = masculine
• υποχρεωτική = feminine
• υποχρεωτικό = neuter

Since the subject is:

• η παρουσία μας = feminine singular

the correct form is:

• είναι υποχρεωτική

Yes. Υποχρεωτικός / υποχρεωτική / υποχρεωτικό is a very common adjective meaning:

• mandatory
• compulsory
• required

For example:

• Η συμμετοχή είναι υποχρεωτική = Participation is mandatory
• Το μάθημα είναι υποχρεωτικό = The course is compulsory

It is especially common in formal, administrative, educational, and workplace language.

In Modern Greek, the verb είμαι is normally expressed, unlike in some other languages where to be can be omitted.

So:

• η παρουσία μας είναι υποχρεωτική = correct
• leaving out είναι would sound incomplete or wrong in standard Greek

Greek can omit subjects, but not usually the main verb to be in this kind of sentence.

The comma separates the sentence into two coordinated parts:

1. Αύριο έχουμε πρωινή σύσκεψη στο γραφείο
2. η παρουσία μας είναι υποχρεωτική

In English, a comma before and can also appear when joining two full clauses. Greek punctuation often does the same, especially when the clauses are relatively long or clearly separate ideas.

So the comma helps readability, though punctuation can vary somewhat by style.

Yes, Greek word order is fairly flexible, but different orders change the emphasis.

For example:

• Αύριο έχουμε πρωινή σύσκεψη στο γραφείο
  Neutral and natural: first gives the time.

• Στο γραφείο έχουμε πρωινή σύσκεψη αύριο
  Possible, but it emphasizes at the office more.

• Η παρουσία μας είναι υποχρεωτική
  Neutral statement.

• Υποχρεωτική είναι η παρουσία μας
  Strong emphasis on mandatory.

So the original sentence is a very natural, standard order for an announcement.

It is mostly neutral to formal, especially because of:

• σύσκεψη = a formal kind of meeting
• η παρουσία μας είναι υποχρεωτική = official/formal phrasing

A more casual version might be something like:

• Αύριο έχουμε meeting στο γραφείο και πρέπει να είμαστε όλοι εκεί.

But the original sounds more polished and appropriate for a workplace notice or internal announcement.
