A diacritic is a glyph added to a letter or to a basic glyph. The term derives from the Ancient Greek διακριτικός, from διακρίνω. The word diacritic is a noun, though it is sometimes used in an attributive sense, whereas diacritical is only an adjective. Some diacritics, such as the acute ⟨á⟩, grave ⟨à⟩, and circumflex ⟨â⟩, are often called accents. Diacritics may appear above or below a letter or in some other position such as within the letter or between two letters.
A macron is a diacritical mark: it is a straight bar ¯ placed above a letter, usually a vowel. Its name derives from Ancient Greek μακρόν (makrón) 'long' because it was originally used to mark long or heavy syllables in Greco-Roman metrics. It now more often marks a long vowel. In the International Phonetic Alphabet, the macron is used to indicate a mid-tone; the sign for a long vowel is instead a modified triangular colon ⟨ː⟩.
O, or o, is the fifteenth letter and the fourth vowel letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is o, plural oes.
Volapük is a constructed language created between 1879 and 1880 by Johann Martin Schleyer, a Catholic priest in Baden, Germany, who believed that God had told him in a dream to create an international language. Notable as the first major constructed international auxiliary language, the grammar comes from European languages and the vocabulary mostly from English. However, the roots are often distorted beyond recognition.
The acute accent, ◌́, is a diacritic used in many modern written languages with alphabets based on the Latin, Cyrillic, and Greek scripts. For the most commonly encountered uses of the accent in the Latin and Greek alphabets, precomposed characters are available.
The double acute accent is a diacritic mark of the Latin and Cyrillic scripts. It is used primarily in Hungarian or Chuvash, and consequently it is sometimes referred to by typographers as hungarumlaut. The signs formed with a regular umlaut are letters in their own right in the Hungarian alphabet—for instance, they are separate letters for the purpose of collation. Letters with the double acute, however, are considered variants of their equivalents with the umlaut, being thought of as having both an umlaut and an acute accent.
Alphabetical order is a system whereby character strings are placed in order based on the position of the characters in the conventional ordering of an alphabet. It is one of the methods of collation. In mathematics, a lexicographical order is the generalization of the alphabetical order to other data types, such as sequences of numbers or other ordered mathematical objects.
Sütterlinschrift is the last widely used form of Kurrent, the historical form of German handwriting that evolved alongside German blackletter typefaces. Graphic artist Ludwig Sütterlin was commissioned by the Prussian Ministry of Science, Art and Culture to create a modern handwriting script in 1911. His handwriting scheme gradually replaced the older cursive scripts that had developed in the 16th century at the same time that letters in books had developed into Fraktur. The name Sütterlin is nowadays often used to refer to several similar varieties of old German handwriting, but Sütterlin's own script was taught only from 1915 to 1941 in all German schools.
A ring diacritic may appear above or below letters. It may be combined with some letters of the extended Latin alphabets in various contexts.
The Syriac alphabet is a writing system primarily used to write the Syriac language since the 1st century AD. It is one of the Semitic abjads descending from the Aramaic alphabet through the Palmyrene alphabet, and shares similarities with the Phoenician, Hebrew, Arabic and Sogdian, the precursor and a direct ancestor of the traditional Mongolian scripts.
Faux Cyrillic, pseudo-Cyrillic, pseudo-Russian or faux Russian typography is the use of Cyrillic letters in Latin text, usually to evoke the Soviet Union or Russia, though it may be used in other contexts as well. It is a common Western trope used in book covers, film titles, comic book lettering, artwork for computer games, or product packaging which are set in or wish to evoke Eastern Europe, the Soviet Union, or Russia. A typeface designed to emulate Cyrillic is classed as a mimicry typeface.
The Common Turkic alphabet is a project of a single Latin alphabet for all Turkic languages based on a slightly modified Turkish alphabet, with 34 letters recognised by the Organization of Turkic States. Its letters are as follows:
A letter is a segmental symbol of a phonemic writing system. The inventory of all letters forms an alphabet. Letters broadly correspond to phonemes in the spoken form of the language, although there is rarely a consistent and exact correspondence between letters and phonemes.
The Latin script, also known as the Roman script, is an alphabetic writing system based on the letters of the classical Latin alphabet, derived from a form of the Greek alphabet which was in use in the ancient Greek city of Cumae, in southern Italy. The Greek alphabet was altered by the Etruscans, and subsequently their alphabet was altered by the Romans. Several Latin-script alphabets exist, which differ in graphemes, collation and phonetic values from the classical Latin alphabet.
The Berber Latin alphabet is the version of the Latin alphabet used to write the Berber languages. It was adopted in the 19th century, using varieties of letters.
Informal or ad hoc romanizations of Cyrillic have been in use since the early days of electronic communications, starting from early e-mail and bulletin board systems. Their use faded with the advances in the Russian internet that made support of Cyrillic script standard, but resurfaced with the proliferation of instant messaging, SMS and mobile phone messaging in Russia.
In Unicode, a script is a collection of letters and other written signs used to represent textual information in one or more writing systems. Some scripts support one and only one writing system and language, for example, Armenian. Other scripts support many different writing systems; for example, the Latin script supports English, French, German, Italian, Vietnamese, Latin itself, and several other languages. Some languages make use of multiple alternate writing systems and thus also use several scripts; for example, in Turkish, the Arabic script was used before the 20th century but transitioned to Latin in the early part of the 20th century. More or less complementary to scripts are symbols and Unicode control characters.
The umlaut is the diacritical mark used to indicate in writing the result of the historical sound shift due to which former back vowels are now pronounced as front vowels.
International auxiliary language orthography is often simplified when compared with natural language orthography.
