Η επιτροπή συναντιέται αύριο.

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

It matches επιτροπή, which is a feminine singular noun:

• η επιτροπή = the committee

It is capitalized here only because it is the first word of the sentence.

In Greek, every noun has a grammatical gender: masculine, feminine, or neuter.

Επιτροπή is a feminine noun, so it takes the feminine article η.

This is grammatical gender, not biological gender. Even though a committee is made up of people of any gender, the word επιτροπή itself is simply feminine as a noun.

Because η επιτροπή is grammatically singular.

Greek verbs agree with the grammatical number of the subject:

• η επιτροπή = singular
• συναντιέται = 3rd person singular

So Greek treats the committee here as one unit, just as English often does in The committee is meeting tomorrow.

Συναντιέται is the 3rd person singular present form of συναντιέμαι.

So:

• συναντιέμαι = I meet / I am meeting
• συναντιέται = he/she/it meets or is meeting

With η επιτροπή, it means:

• the committee meets
• the committee is meeting

depending on the context.

That is a very common question.

Greek has a set of endings often called middle/passive or mediopassive. A verb with those endings does not always have a truly passive meaning.

Συναντιέμαι is one of those verbs. In many contexts it means something active or reciprocal, like:

• meet
• meet with
• get together

So συναντιέται here does not mean is being met. It means meets / is meeting.

The verb form is present, but the sentence refers to the future because of αύριο (tomorrow).

Greek often uses the present tense for a planned or scheduled future event, just like English does in sentences such as:

• The committee meets tomorrow
• The committee is meeting tomorrow

So Η επιτροπή συναντιέται αύριο is completely natural Greek.

Yes, absolutely.

That is also a very natural sentence:

• Η επιτροπή θα συναντηθεί αύριο

A simple way to feel the difference is:

• συναντιέται αύριο = sounds like a planned/scheduled arrangement
• θα συναντηθεί αύριο = straightforward future

In many real situations, both are possible.

Because the sentence does not say who the committee is meeting with. It just says that the committee is meeting.

If you want to add the other party, Greek often uses με:

• Η επιτροπή συναντιέται με τον διευθυντή αύριο.
• The committee is meeting with the director tomorrow.

So the original sentence is complete on its own; it simply leaves that detail unstated.

Here αύριο functions as an adverb of time, meaning tomorrow.

Greek often uses time words directly, without a preposition:

• σήμερα = today
• αύριο = tomorrow
• χθες / χτες = yesterday

So you do not need a word like on or at before αύριο.

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

The original sentence is neutral and natural:

• Η επιτροπή συναντιέται αύριο.

But you could also say:

• Αύριο η επιτροπή συναντιέται.
• Η επιτροπή αύριο συναντιέται.

The basic meaning stays the same, but the emphasis changes a little:

• putting αύριο first highlights tomorrow

A learner will usually want to notice the stress:

• Η — pronounced ee
• επιτροπή — stress on the last syllable: επιτροΠΗ
• συναντιέται — stress on -τιέ-
• αύριο — stress on the first syllable: Αύριο

A rough pronunciation guide is:

• i epitropEE sinandjEte AVrio

For αύριο, the αυ is pronounced like av here.
