À bientôt !

A common pronunciation is ah byan-toh.

More precisely:

• À sounds like ah
• bien sounds roughly like byan
• tôt sounds like toh

In IPA, it is usually /a bjɛ̃.to/.

A few notes:

• The n in bien is not fully pronounced as an English n; it helps create a nasal vowel.
• The final t in bientôt is silent.

The accent in À is a grave accent: à.

Here, it marks the word à, which is a very common preposition often meaning to, at, or in depending on context. In À bientôt, it helps distinguish à from a:

• à = a preposition
• a = has (from the verb avoir)

So the accent is important for spelling, even though it does not change pronunciation very much here.

Bientôt literally means soon.

It is made up historically from:

• bien = well
• tôt = early

But as a learner, the useful meaning to remember is simply soon.

So À bientôt ! is literally something like Until soon!, which is why it is used like See you soon!

In this expression, à helps create a fixed farewell phrase.

French often uses à + time expression in goodbyes:

• À demain ! = See you tomorrow!
• À lundi ! = See you Monday!
• À bientôt ! = See you soon!

So it is best learned as a whole expression rather than translated word-for-word every time.

It is generally neutral and very common. You can use it in both:

• informal situations with friends
• polite everyday situations with coworkers, neighbors, customers, etc.

It is not extremely formal, but it is perfectly acceptable in normal polite speech.

Use À bientôt ! when you expect or hope to see the person again fairly soon.

Use Au revoir ! as a more general goodbye.

The difference is:

• Au revoir ! = goodbye / see you again
• À bientôt ! = see you soon

So À bientôt ! feels a bit warmer or more specific because it suggests another meeting before too long.

Yes, sometimes.

It often expresses:

• a real expectation of seeing someone again soon
• or simply a friendly hope

So people may use it even if the next meeting is not scheduled exactly. However, if soon would sound strange in the situation, Au revoir ! may be safer.

Yes, several very common ones:

• À plus ! / À plus tard ! = See you later
• À demain ! = See you tomorrow
• À tout à l’heure ! = See you very soon / see you in a little while
• À la prochaine ! = Until next time
• Au revoir ! = Goodbye

These all work a bit like À bientôt !, but they differ in how specific they are about time.

Yes. It is a complete, fixed farewell expression on its own.

You do not need to add anything else. For example:

• Merci, à bientôt !
• Bonne journée, à bientôt !

Used alone, it sounds perfectly natural.

Not very much. À bientôt ! and À bientôt. both appear in writing.

The exclamation mark makes it feel a little more lively or friendly, which is common in greetings and farewells. In messages, emails, or casual writing, À bientôt ! is very natural.
