Umlaudeds

Umlaudeds, also known as umlauted characters, are diacritical marks consisting of two dots placed over a vowel letter in various writing systems. Originating from the German language, the umlaut (derived from the German word *Umlaut*, meaning "change of sound") was historically used to denote a secondary vowel sound in Old High German. Over time, its usage expanded to represent phonetic shifts and to distinguish between homophones in multiple languages.

In German, the umlaut marks the fronting of a vowel sound, such as changing *a* to *ä*, *o* to *ö*, and *u* to *ü*. For example, the word *Mutter* (mother) uses *ü* to differentiate it from *Mutter* (motherly) or *Mutter* (matronly). Similar adaptations appear in other Germanic languages, including Swedish, Norwegian, Danish, and Icelandic, where umlauts serve phonetic or orthographic purposes.

Beyond Germanic languages, umlauts appear in other contexts, such as in the Finnish language, where they indicate nasalized vowels, or in some loanwords in English, such as *München* (Munich) or *Hülle* (hull). In some cases, umlauts are used to represent special characters or to denote specific meanings in scientific or technical notation.

The umlaut is distinct from other diacritical marks like the acute (*é*), grave (*è*), or circumflex (*â*), which serve different phonetic functions. While once a standard feature of German orthography, modern German spelling reforms have occasionally debated its necessity, though it remains widely used. In digital typography, umlauted characters are supported in Unicode, allowing for consistent representation across various platforms.
