Buonanotte, ci vediamo domani.

As a greeting or farewell, buonanotte is normally written as one word in modern Italian.

• Buonanotte! = Good night!
• Buona notte can exist too, but it sounds more literal, like have a good night rather than the standard fixed expression.

So in your sentence, Buonanotte as one word is the normal choice.

Use buonasera for good evening, when you greet someone in the evening.

Use buonanotte when:

• someone is going to bed,
• you are leaving late at night,
• or you are ending the day and saying good night.

So:

• Buonasera = Good evening
• Buonanotte = Good night

If you say Buonanotte, ci vediamo domani, it suggests you are parting for the night and expecting to meet again the next day.

Here, ci means each other / ourselves, depending on how you explain it.

The verb is based on vedersi, which can mean to see each other. So:

• ci vediamo = literally we see each other
• natural English: see you or we’ll see each other

In this sentence, ci does not mean there. It is the pronoun that makes the idea reciprocal: the speaker and the listener will see one another.

Because Italian often uses the present tense to talk about the near future, especially when the time is already clear.

• Ci vediamo domani = literally We see each other tomorrow
• natural meaning = See you tomorrow / We’ll see each other tomorrow

This is very common and completely normal in Italian.

English does something similar in sentences like:

• I’m leaving tomorrow
• We meet next week

So even though vediamo is present tense, domani makes the future meaning clear.

Yes. Ci vedremo domani is also correct and means we will see each other tomorrow.

The difference is mainly style:

• Ci vediamo domani = more common, natural, conversational
• Ci vedremo domani = a little more explicitly future

In everyday speech, Italians very often prefer the present tense for planned future events, so ci vediamo domani is probably the most natural version.

Because Italian usually doesn’t need subject pronouns when the verb ending already shows who the subject is.

• vediamo already means we see
• so noi is unnecessary unless you want emphasis

That is why Italian often sounds more compact than English.

• (Noi) ci vediamo domani
• Both are correct, but the version without noi is more normal.

It is generally neutral and common, and you can use it in many situations.

However, it does imply a certain shared expectation: we’ll be seeing each other. Because of that, it often feels natural with:

• friends,
• classmates,
• coworkers,
• people you already know.

In a more formal or less personal context, Italians might instead say:

• Arrivederci
• A domani = See you tomorrow
• Ci vediamo domani can still be fine, but it sounds a bit more direct and personal.

They are very close, but not exactly identical.

• A domani = See you tomorrow
• Ci vediamo domani = literally we’ll see each other tomorrow

A domani is shorter and very common. Ci vediamo domani is slightly fuller and more explicit.

Both work well when saying goodbye at night if you know you will meet again the next day.

Yes. Domani is flexible.

You can say:

• Ci vediamo domani
• Domani ci vediamo

Both are correct.

The most neutral and common order here is ci vediamo domani. Putting domani first can add a little emphasis to tomorrow.

A simple pronunciation guide:

• Buonanotte ≈ bwoh-nah-NOT-teh
• ci vediamo domani ≈ chee veh-DYAH-mo doh-MAH-nee

A few helpful points:

• ci sounds like chee
• ve sounds like veh
• diamo in vediamo has a dyah sound: veh-DYAH-mo
• double tt in buonanotte is pronounced more strongly than a single t

The main stress falls on:

• buonanOTte
• vediAmo
• doMAni

Yes, absolutely. It sounds natural and idiomatic.

It works well when:

• you are ending the evening,
• saying good night,
• and you expect to see the person again the next day.

For example, between family members, friends, roommates, classmates, or coworkers, it would sound perfectly normal.

Yes. It can work in both cases.

Italian ci includes the speaker together with the other person or people:

• to one person: you and I will see each other
• to several people: you all and I will see each other

So Buonanotte, ci vediamo domani can be said to:

• one friend,
• your family,
• a group of coworkers,
• or several classmates.

Not very naturally. A word-for-word translation would be something like:

• Good night, we see each other tomorrow

That helps you understand the grammar, but it is not natural English.

The natural English translation is:

• Good night, see you tomorrow.

This is a good example of how Italian and English often express the same idea differently.
