An umlaut is a diacritical mark consisting of two dots placed over a vowel, typically used in languages such as German, Finnish, and Swedish.
In linguistic terms, it modifies the sound of the vowel, often indicating a change in pronunciation. For example, in German, the umlaut can transform vowels like “a,” “o,” and “u” into ä, ö, and ü, respectively.
Besides its linguistic function, the umlaut is also used in typography to represent various sounds and characters in different languages and writing systems.
