Ö
Ö, or ö, is a letter, representing a vowel, in the Finnish, Swedish, Icelandic, Estonian, Hungarian and Turkish alphabets. It also appears in the German alphabet, where it represents "O" with umlaut, and is alphabetized together with "O".
The origin of the letter form was as a ligature for the digraph "OE". In the Danish and Norwegian alphabets, "Ø" is the equivalent.
In Swedish, ö is even an entire word, meaning island.
