À demain.

In this expression, à has the sense of until / see you at rather than its basic dictionary meaning of to or at.

So À demain is a fixed farewell expression meaning something like:

• See you tomorrow
• Until tomorrow

You do not need to translate it word-for-word to use it correctly.

French often uses short, elliptical expressions in everyday speech, especially for greetings and goodbyes.

So À demain is a shortened farewell. It leaves out the full sentence, but the meaning is still clear from context.

You can think of it as similar to English expressions like:

• See you tomorrow
• Till tomorrow

It is completely natural in French to use just À demain by itself.

Use À demain when you are saying goodbye to someone and you expect to see them tomorrow.

For example:

• leaving work in the evening and seeing coworkers the next day
• saying goodbye to a classmate after school
• ending a phone call when you know you will meet tomorrow

If you are not sure you will see the person tomorrow, a more general goodbye like au revoir may fit better.

À demain is generally neutral. It works in both informal and fairly formal situations.

You can say it to:

• friends
• classmates
• coworkers
• teachers
• neighbors

Its level of formality usually depends more on your tone and the situation than on the phrase itself.

Usually, no. If you are saying goodbye, À demain is the normal expression.

Saying only demain would usually sound incomplete, because demain by itself just means tomorrow. It is not normally used alone as a farewell.

So if you mean See you tomorrow, say:

• À demain

not just:

• demain

It is pronounced approximately:

ah duh-MAN
More accurately in IPA: /a də.mɛ̃/

A few pronunciation notes:

• À sounds like a simple open a
• The de- in demain is a light duh
• The final -main has a nasal vowel, so the n is not fully pronounced like an English n

The last syllable is the trickiest part for English speakers. Try to hear and imitate the nasal sound in demain rather than pronouncing a strong final n.

Yes. You can make it more specific by adding a time reference.

Common examples:

• À demain matin — see you tomorrow morning
• À demain soir — see you tomorrow evening
• À demain, 8 heures — see you tomorrow at 8 o’clock

This is very natural if you want to be more precise about when you will see the person.

Au revoir is a general goodbye. It does not say when you will see the person again.

À demain is more specific: it says or implies that you will see them tomorrow.

So:

• Au revoir = goodbye / see you again
• À demain = see you tomorrow

If tomorrow is the expected next meeting, À demain is often the more natural choice.

Because the sentence begins with À, and in correct French spelling, capital letters keep their accents.

So the correct form is:

• À demain

not:

• A demain

Leaving off the accent is common in casual typing sometimes, but standard written French keeps it.

Yes. Both are possible:

• À demain.
• À demain !

The difference is just tone:

• À demain. is neutral
• À demain ! sounds warmer, more cheerful, or more energetic

In speech, tone of voice matters more than punctuation.
