Έχουμε μισή ώρα να πιούμε έναν καφέ πριν από την αναχώρηση.

Yes. Έχουμε literally means we have.

In Greek, έχω is often used the same way as English have in time expressions:

• Έχουμε χρόνο. = We have time.
• Έχουμε δέκα λεπτά. = We have ten minutes.

So in this sentence, Έχουμε μισή ώρα... means We have half an hour...

Because ώρα is a feminine noun, and the adjective μισός must agree with it in gender, number, and case.

The basic forms are:

• μισός = masculine
• μισή = feminine
• μισό = neuter

Since ώρα is feminine, Greek uses μισή ώρα = half an hour.

Compare:

• μισός καφές = half a coffee
• μισή ώρα = half an hour
• μισό λεπτό = half a minute

Because Greek often does not need a separate word for for in expressions like this.

English says:

• We have half an hour

Greek simply says:

• Έχουμε μισή ώρα

The duration is expressed directly by the noun phrase. This is very natural in Greek.

Να πιούμε means something like to drink in this context, but more literally it is a να-clause built with the verb πίνω.

• πίνω = I drink / I am drinking
• πιούμε = we drink, in the form used after να

Greek often uses να + verb where English uses an infinitive:

• Θέλω να φύγω. = I want to leave.
• Έχουμε χρόνο να μιλήσουμε. = We have time to talk.
• Έχουμε μισή ώρα να πιούμε έναν καφέ. = We have half an hour to drink a coffee.

So Greek does not use an infinitive like English to drink here. It uses να πιούμε instead.

This is a very important Greek grammar point.

• πίνουμε = imperfective form, focusing on the action as ongoing or repeated
• πιούμε = perfective subjunctive form after να, focusing on the action as a single complete event

Here, the sentence means to have a coffee / drink a coffee as one complete action before departure. That is why Greek uses να πιούμε.

Compare the idea:

• να πίνουμε καφέ = to be drinking coffee / to drink coffee regularly
• να πιούμε έναν καφέ = to drink a coffee (one occasion, one complete event)

So πιούμε is the natural choice here.

Historically, να comes from an older construction, but in modern Greek you should usually think of να + verb as a standard grammar structure, not translate it word-for-word.

In many cases, English uses:

• to drink
• so that we drink
• let’s drink
• that we drink

Greek often uses να for functions that English expresses in different ways.

Here, the best understanding is simply:

• να πιούμε έναν καφέ = to have/drink a coffee

So yes, a literal word-for-word translation can sound awkward. It is better to learn the whole pattern.

Because καφέ is masculine, singular, and it is the direct object of πιούμε.

The article ένας changes by case:

• nominative: ένας
• accusative: έναν

Since the sentence is about drinking a coffee, coffee is the object, so Greek uses the accusative:

• έναν καφέ

This is the normal pattern:

• Βλέπω έναν φίλο. = I see a friend.
• Θέλω έναν καφέ. = I want a coffee.
• Να πιούμε έναν καφέ. = To drink/have a coffee.

Because καφές is the dictionary form, which is nominative singular. Here it is in the accusative singular, so the ending changes.

For this masculine noun:

• nominative: ο καφές
• accusative: τον καφέ

So after έναν, you get:

• έναν καφέ

This is a common pattern for masculine nouns ending in -ές.

It can absolutely have the broader social meaning, just like in English.

In Greek, πάμε για καφέ and να πιούμε έναν καφέ often mean not only consuming coffee, but also sitting down together for a coffee/chat/break.

So depending on context, it may suggest:

• literally drinking a coffee
• grabbing a coffee
• sitting for a quick coffee before leaving

Πριν από means before.

In this sentence:

• πριν από την αναχώρηση = before the departure

Greek uses πριν από before a noun phrase.

Examples:

• πριν από το μάθημα = before the lesson
• πριν από το ταξίδι = before the trip
• πριν από την αναχώρηση = before the departure

You may also hear πριν by itself in some contexts, but πριν από + noun is a very standard and clear structure.

Yes, in everyday Greek many speakers do say πριν την αναχώρηση.

Both are heard:

• πριν από την αναχώρηση
• πριν την αναχώρηση

The version with από is often felt to be a bit more explicit or formal, but both are natural.

Learners should definitely recognize both.

Because αναχώρηση is a feminine noun, and after πριν από it appears in the accusative.

So:

• nominative: η αναχώρηση
• accusative: την αναχώρηση

That is why Greek says:

• πριν από την αναχώρηση

This is the normal article + noun agreement pattern.

Yes, αναχώρηση means departure.

It is a fairly standard and slightly formal noun. You might see or hear it in contexts like:

• airports
• train stations
• travel schedules
• announcements

Examples:

• ώρα αναχώρησης = departure time
• πριν από την αναχώρηση = before departure

In casual speech, people might sometimes choose a simpler phrasing with a verb instead, depending on context.

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

The given sentence is very natural:

• Έχουμε μισή ώρα να πιούμε έναν καφέ πριν από την αναχώρηση.

But other arrangements are possible, for example if you want to emphasize time or the departure:

• Πριν από την αναχώρηση, έχουμε μισή ώρα να πιούμε έναν καφέ.

The original order sounds neutral and straightforward.

A rough pronunciation guide is:

EH-hoo-me MEE-see OH-ra na PYOO-me EH-nan ka-FEH preen A-po teen a-na-HO-ree-see

A few useful notes:

• χ in έχουμε is the Greek sound heard in Scottish loch or German Bach
• πιούμε has two vowel sounds together, roughly pyoo-me
• stress matters a lot in Greek:
  • Έχουμε
  • μισή
  • ώρα
  • πιούμε
  • καφέ
  • αναχώρηση

It is perfectly understandable and natural.

A speaker might also say slightly more everyday versions depending on context, such as:

• Έχουμε μισή ώρα να πιούμε έναν καφέ πριν φύγουμε.
• Έχουμε μισή ώρα για έναν καφέ πριν την αναχώρηση.

But the original sentence is completely normal, especially in a travel-related context where αναχώρηση fits well.
