Η έκδοση γίνεται αύριο.

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

It matches έκδοση, which is a feminine singular noun:

• η έκδοση = the release / the edition / the publication

Greek articles change for gender, number, and case, so you cannot always use just one form like English the.

Because every Greek noun has a grammatical gender, and έκδοση is a feminine noun.

That does not necessarily mean the thing itself is feminine in any real-world sense. It is just a grammatical category. Since έκδοση is feminine, it takes the feminine article η in the nominative singular:

• η έκδοση

It is in the nominative singular.

In this sentence, η έκδοση is the subject of the verb:

• Η έκδοση γίνεται αύριο.
• The release takes place tomorrow.

Subjects are normally in the nominative.

Γίνεται is the 3rd person singular present form of γίνομαι.

Depending on context, γίνομαι can mean:

• become
• happen
• take place
• be held
• be done in some expressions

In this sentence, it most naturally means something like:

• takes place
• happens
• is happening
  depending on the translation you were given.

So Η έκδοση γίνεται αύριο means that the event/process is scheduled for tomorrow.

Greek often uses the present tense for a scheduled or arranged future event, just like English sometimes does.

Compare English:

• The meeting is tomorrow.
• The train leaves at 8.

Greek does the same kind of thing:

• Η έκδοση γίνεται αύριο.

So the present tense here gives the idea of something planned or set.

Yes. Η έκδοση θα γίνει αύριο is also correct.

The difference is roughly this:

• γίνεται αύριο = present used for a scheduled/planned future event
• θα γίνει αύριο = straightforward future, will happen / will take place tomorrow

In many contexts both are natural. The version without θα can sound a bit more like a fixed arrangement or timetable.

Because γίνεται is the normal present indicative form used in a statement like this.

Γίνει is a different form, used in structures such as:

• να γίνει = to happen / to become
• θα γίνει = it will happen / become

So:

• Η έκδοση γίνεται αύριο. = correct
• Η έκδοση γίνει αύριο. = not correct by itself

It looks like a middle/passive-form verb, but here it is best understood as the verb γίνομαι, which is very commonly used with meanings like happen, become, or take place.

So in this sentence, it is not really a passive equivalent of English is done in the usual sense. It is simply the normal verb form meaning takes place / happens.

Έκδοση can mean several related things depending on context, such as:

• edition
• publication
• release
• issuance

So the exact English word depends on what meaning was already given to you. Grammatically, though, the sentence structure stays the same.

Yes. Greek word order is more flexible than English.

The neutral order here is:

• Η έκδοση γίνεται αύριο.

But you could also hear:

• Αύριο γίνεται η έκδοση.
• Γίνεται αύριο η έκδοση.

These versions shift emphasis:

• putting αύριο first emphasizes tomorrow
• putting the verb first can sound more contextual or stylistic

The original sentence is a very natural, standard order.

Greek usually does not need a preposition before αύριο.

So:

• αύριο = tomorrow

You simply say:

• γίνεται αύριο = it takes place tomorrow

This is similar to English, where we also usually say tomorrow, not on tomorrow.

A simple pronunciation guide is:

• Η έκδοση γίνεται αύριο
• ee EK-tho-see YEE-ne-te AV-rio

A few notes:

• η sounds like ee
• ξ in έκδοση sounds like ks
• δ in modern Greek sounds like the th in this
• γ before ι in γίνεται sounds like a soft sound, often approximated in learner guides as y
• stress matters:
  • Ékdosi
  • YÍnete
  • Ávrio

Normally, you would keep the article:

• Η έκδοση γίνεται αύριο.

Leaving it out would usually sound unnatural unless you were speaking in a very special style, like headlines, notes, or fragmented speech.

In ordinary Greek, countable singular nouns used as subjects typically take the article when they are definite.

It is 3rd person singular.

That matches the singular subject:

• η έκδοση = the release / publication / edition

So:

• η έκδοση γίνεται
• the release happens / takes place

If the subject were plural, the verb would also be plural.

It is neutral and standard. It works well in both everyday and more formal contexts.

There is nothing especially slangy or especially literary about it. It is a normal, useful sentence pattern for talking about scheduled events:

• Η συνάντηση γίνεται αύριο. = The meeting is tomorrow / takes place tomorrow.
• Η παρουσίαση γίνεται αύριο. = The presentation is tomorrow.

Yes, in other contexts γίνεται can mean becomes / is becoming, because it comes from γίνομαι.

For example:

• Γίνεται καλύτερος. = He is becoming better.

But in your sentence, because the subject is η έκδοση and the time word is αύριο, the natural meaning is takes place / happens tomorrow, not becomes tomorrow.

The structure is:

• subject + verb + time expression

So:

• Η έκδοση = subject
• γίνεται = verb
• αύριο = time expression

This is a very common Greek pattern:

• Το μάθημα αρχίζει αύριο.
• Η γιορτή γίνεται το βράδυ.

It is a good model to remember.
