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.
Æ is a character formed from the letters a and e, originally a ligature representing the Latin diphthong ae. It has been promoted to the status of a letter in some languages, including Danish, Norwegian, Icelandic, and Faroese. It was also used in Old Swedish before being changed to ä. The modern International Phonetic Alphabet uses it to represent the near-open front unrounded vowel. Diacritic variants include Ǣ/ǣ, Ǽ/ǽ, Æ̀/æ̀, Æ̂/æ̂ and Æ̃/æ̃.
Welsh orthography uses 29 letters of the Latin script to write native Welsh words as well as established loanwords.
The alphabet for Modern English is a Latin-script alphabet consisting of 26 letters, each having an upper- and lower-case form. The word alphabet is a compound of the first two letters of the Greek alphabet, alpha and beta. The alphabet originated around the 7th century to write Old English from Latin script. Since then, letters have been added or removed to give the current letters:
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.
A digraph or digram is a pair of characters used in the orthography of a language to write either a single phoneme, or a sequence of phonemes that does not correspond to the normal values of the two characters combined.
A trigraph is a group of three characters used to represent a single sound or a combination of sounds that does not correspond to the written letters combined.
German orthography is the orthography used in writing the German language, which is largely phonemic. However, it shows many instances of spellings that are historic or analogous to other spellings rather than phonemic. The pronunciation of almost every word can be derived from its spelling once the spelling rules are known, but the opposite is not generally the case.
Italian orthography uses 21 letters of the 26-letter Latin alphabet to write the Italian language. This article focuses on the writing of Standard Italian, based historically on the Florentine dialect, and not the other Italian dialects.
The Royal Thai General System of Transcription (RTGS) is the official system for rendering Thai words in the Latin alphabet. It was published by the Royal Institute of Thailand in early 1917, when Thailand was called Siam.
Dutch orthography uses the Latin alphabet. The spelling system is issued by government decree and is compulsory for all government documentation and educational establishments.
Benjamin Franklin's phonetic alphabet was Benjamin Franklin's proposal for a spelling reform of the English language. The alphabet was based on the Latin alphabet used in English.
C, or c, is the third 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 cee. Cees is the plural form for this letter.
In the Latin-based orthographies of many European languages, the letter ⟨g⟩ is used in different contexts to represent two distinct phonemes that in English are called hard and soft ⟨g⟩. The sound of a hard ⟨g⟩ is usually the voiced velar plosive while the sound of a soft ⟨g⟩ may be a fricative or affricate, depending on the language. In English, the sound of soft ⟨g⟩ is the affricate, as in general, giant, and gym. A ⟨g⟩ at the end of a word usually renders a hard ⟨g⟩, while if a soft rendition is intended it would be followed by a silent ⟨e⟩.
Wolofal is a derivation of the Arabic script for writing the Wolof language. It is basically the name of a West African Ajami script as used for that language.
The Rheinische Dokumenta is a phonetic writing system developed in the early 1980s by a working group of academics, linguists, local language experts, and local language speakers of the Rhineland. It was presented to the public in 1986 by the Landschaftsverband Rheinland.
The Cyrillic script family contains many specially treated two-letter combinations, or digraphs, but few of these are used in Slavic languages. In a few alphabets, trigraphs and even the occasional tetragraph or pentagraph are used.
