Umlaut () is a name for the
two dots diacritical mark

I-mutation (also known as umlaut, front mutation, i-umlaut, i/j-mutation or i/j-umlaut) is a type of sound change in which a back vowel is fronted or a front vowel is raised if the following syllable contains , or (a voiced palatal approxi ...

In German, the umlaut diacritic indicates that the short back vowels and the diphthong are pronounced ("shifted forward in the mouth") as follows:
* →

And the long back vowels are pronounced in the front of the mouth as follows:

is the latest and best-known example) the letter was composed of two short vertical lines very close together, and the superscript looked like two tiny strokes. Even from the 16th century, the handwritten convention of indicating umlaut by two dots placed above the affected vowel is also found in printed texts.
Unusual umlaut designs are sometimes also created for graphic design purposes, such as to fit umlaut dots into tightly spaced lines of text.
This may include umlaut dots placed vertically or inside the body of the letter.
Printing conventions in German
When typing German with a keyboard that doesn't have umlaut letters, it is usual to replace them with the underlying vowel followed by an . So, for example, "Schröder" becomes "Schroeder". As the pronunciation differs greatly between the normal letter and the umlaut, simply omitting the dots would be incorrect. The result would often be a different word, as in "already", "beautiful"; or a different grammatic form, e.g. "mother", "mothers".
Despite this, the umlauted letters are not considered to be separate letters of the alphabet in German, in contrast to the situation in other Germanic languages.
When
alphabetically sorting German words, the umlaut is usually not distinguished from the underlying vowel, although if two words differ only by an umlaut, the umlauted one comes second, for example:
# schon
# schön
# schonen
There is a second system in limited use, mostly for sorting names (such as in telephone directories), which treats letters with umlauts as their base equivalents followed by e.
# schön
# schon

Swiss typewriter keyboards use the same keys for French accents (in Swiss French) as are used for German umlauts (in Swiss German) and which version is active (on a computer) is chosen by system setting. Consequently to apply an accent or umlaut to a capital letter requires use of a

Slovak uses the letter to denote (or a bit archaic but still correct ). The sign is called ("two dots"), and the full name of the letter ''ä'' is ("wide e"). The similar word ("double dot") however refers to the

In these languages, with the exception of Hungarian, the replacement rule for situations where the umlaut character is not available, is to simply use the underlying unaccented character instead. Hungarian follows the German rules and replaces and with and respectively – at least for telegrams and telex messages. The same rule is followed for the near-lookalikes and .

When
Turkish switched from the Arabic to the Latin alphabet in 1928, it adopted a number of diacritics borrowed from various languages, including and from German (probably reinforced by their use in languages like Swedish, Hungarian, etc.).

, this means they have their own positions in the alphabet, for example at the end ("A–Ö" or "A–Ü", not "A–Z") as in Swedish, Estonian and Finnish, which means that the dictionary order is different from German. The transformations ''ä'' → ''ae'' and ''ö'' → ''oe'' can, therefore, be considered less appropriate for these languages, although Swedish and Finnish passports use the transformation to render ö and ä (and ''å'' as ''aa'') in the
machine-readable zone. In contexts of technological limitation, e.g. in English based systems, Swedes can either be forced to omit the diacritics or use the two letter system.
When typing in
Norwegian, the letters
Æ and
Ø might be replaced with
Ä and
Ö respectively if the former are not available. If ''ä'' is not available either, it is appropriate to use ''ae''. The same goes for ''ö'' and ''oe''. While ''ae'' has a great resemblance to the letter ''æ'' and, therefore, does not impede legibility, the digraph ''oe'' is likely to reduce the legibility of a Norwegian text. This especially applies to the digraph ''
øy'', which would be rendered in the more cryptic form ''oey''. Also in
Danish, Ö has been used in place of Ø in some older texts and to distinguish between open and closed ö-sounds and when confusion with other symbols could occur, e.g. on maps. The Danish/Norwegian Ø is like the German Ö a development of OE, to be compared with the French
Œ.
