A similar glyph, A with umlaut, appears in the German alphabet. It represents the umlauted form of a, resulting in [?] (or [e] for many speakers). In German, it is called "Ä" (pronounced [?]) or "Umlaut-A".
Ā, lowercase ā, is a grapheme, a Latin A with a macron, used in several orthographies. The macron is only considered when sorting words that are otherwise identical. For example, in Māori, tāu (meaning your) comes after tau (meaning year), but before taumata (hill).
It's used in Danish, Norwegian, Swedish and the Belgian Romance language called Walloon. They also use it in Czech, but there it's called a kroužek. Additionally, Å is the correct abbreviation for the unit of length called the Ångström (or Ångstrøm).
Hold down the ALT-key, and then, by using the numeric keypad (on the right), type the character code. Then, release the ALT-key. 1. Hold down the Option key, and type a u (the letter u).
Ö, or ö, is a character that represents either a letter from several extended Latin alphabets, or the letter o modified with an umlaut or diaeresis. In many languages, the letter ö, or the o modified with an umlaut, is used to denote the non-close front rounded vowels [ø] or [œ].
German uses three letter-diacritic combinations (Ä/ä, Ö/ö, Ü/ü) using the umlaut and one ligature (ß (called Eszett (sz) or scharfes S, sharp s)) which are officially considered distinct letters of the alphabet. In the past, long s (ſ) was used as well, as in English and many other European languages.
Á, á (a-acute) is a letter of the Blackfoot, Czech, Dutch, Faroese, Galician, Hungarian, Icelandic, Irish, Kazakh, Lakota, Navajo, Occitan, Portuguese, Sámi, Slovak, Spanish, Vietnamese, and Welsh languages as a variant of the letter a.
The letter "Ø" is sometimes used in mathematics as a replacement for the symbol "∅" (Unicode character U+2205), referring to the empty set as established by Bourbaki, and sometimes in linguistics as a replacement for same symbol used to represent a zero.
Properly speaking, only German and Hungarian words have these two dots over a vowel to indicate a change in sound (as in doppelgänger and über), but loosely, people sometimes refer to its twin, the dieresis (as in naïve) as an umlaut. The word is German and means "change of sound," from um, "about," and laut, "sound."
In case your feelings about punctuation are similar, here's the basics: the semicolon is the one with a dot and a comma on top of each other, like this; and the colon is the one with two dots, like this: Semicolons (like commas, periods, dashes, etc.) are rest and breathing markers.
Angstrom (Å), unit of length used chiefly in measuring wavelengths of light, equal to 10−10 metre, or 0.1 nanometer. It is named for the 19th-century Swedish physicist Anders Jonas Ångström.
A tittle or superscript dot is a small distinguishing mark, such as a diacritic or the dot on a lowercase i or j. The tittle is an integral part of the glyph of i and j, but diacritic dots can appear over other letters in various languages.
The result of the dots, so the letter with the dots on it, is an Umlaut – literally a “resounding” – of the vowel. The dots themselves are commonly known as ä/ö/ü-Striche (or Strichelchen), depending on what word you have in mind.
The Swedish å-sound can either be a long sound or a short one. When being long it is pronounced like the English word fore. The short sound as in yonder. Listen to the pronunciation of the different sounds through the links below.
For English speakers these include the umlauted vowels ö and ü. Fortunately, there is a very effective method you can use for arriving at these sounds. To pronounce the ö-sound, say “ay” as in day (or as in the German word See). While continuing to make this sound, tightly round your lips.
Ë, ë (e-diaeresis) is a letter in the Albanian, Kashubian, Emilian-Romagnol and Ladin alphabets. The letter is also used in Seneca, Taiwanese Hokkien, Turoyo and Uyghur when written in Latin script.
For the umlauted characters, hold down OPTION and push 'u'. Release OPTION, then type the desired base letter (a, o, u, A, O, or U). The umlaut will appear over the letter you typed. (So to type ü, you should hold down OPTION, press u, then release OPTION and press u again.)
A glyph, U with umlaut, appears in the German alphabet. It represents the umlauted form of u, which results in the same sound as the [y]. It can also represent [?]. In Swedish the letter is called tyskt y which means German y.
