Formal:
* Tutaonana hivi karibuni: This literally translates to "We will see each other soon," and is a polite way to say goodbye.
* Tutaonana baadaye: This translates to "We will see each other later," which is also appropriate for a formal farewell.
Informal:
* Tutaonana: This is a simple and casual way to say "See you soon."
* Tutaonana tena: This translates to "We will see each other again," and is a more heartfelt way to say goodbye.
In addition to the above, you could also use:
* Kwaheri: This is a general goodbye, similar to "goodbye" in English.
* Usiku mwema: This means "Good night" and is appropriate if you are saying goodbye in the evening.
* Asante: This means "Thank you" and can be used as a way to express gratitude and imply that you will see the person again soon.
Remember: The best way to say "See soon" in Swahili depends on your relationship with the person you are talking to and the situation.
