ä – umlaut, small letter

Ä – umlaut, capital letter

ö – umlaut, small letter

Ö – umlaut, capital letter

ü – umlaut, small letter

Ü – umlaut, capital lette

ß – eszett or sharp s


The letters ä ö ü

The umlaut letters ä ö ü are on German computer keyboards. Character encodings are used to render them on a non-German keyboard. If the umlauts are unavailable, they are replaced by ae, oe, and ue. Gepäck, Köln, and München are typed as Gepaeck, Koeln, and Muenchen.

The letter ß

The letter ß represents a voiceless s. Since it is never used at the beginning of a word, it exists only as a small letter. If it is not available for typing or printing, ss is used instead. So the word groß.
