Learn German: Auf Wiedersehen, Frau Klein!

It literally translates to "until we see each other again". Auf can mean "on" or "to", and Wiedersehen is a noun made from wieder (again) and sehen (to see). Notice that Wiedersehen is capitalized because all nouns in German get a capital letter!

Is Auf Wiedersehen a formal or informal way to say goodbye?

It is the standard, polite, and slightly formal way to say goodbye. Since we are addressing someone as Frau Klein (using her title and last name), this formal goodbye matches perfectly. With friends or family, you would typically use the more informal Tschüss (bye).

Does the word Frau always mean "Mrs."?

When placed before a last name, like Frau Klein, it acts as the title "Mrs." or "Ms.". But when used as a regular noun in a sentence, Frau simply means "woman" or "wife".

Does the name Klein mean anything in German?

Yes, klein is a very common German adjective that means "small" or "little". Just like in English, many German last names come from everyday describing words or professions.
