Ö

Ö or ö is not a letter used in English, but is used in some other languages, such as German, Finnish, Estonian, Hungarian and Swedish.

German

Germany and Austria

Ö or ö is one of the 4 extra letters used in German. It can be replaced by using the letters Oe or oe. In English language newspapers it is often written as O or o but this is not correct.

Internet addresses are written as "oe" because the internet address system can only understand ordinary English letters.

Switzerland

German is one of the official languages of Switzerland. However, in Swiss version of the German langauge (Swiss-Deutsch) Ö or ö is invariably replaced by Oe or oe.
