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 ⟨ó⟩, grave ⟨ò⟩, and circumflex ⟨ô⟩, 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 of 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.
The ogonek is a diacritic hook placed under the lower right corner of a vowel in the Latin alphabet used in several European languages, and directly under a vowel in several Native American languages. It is also placed on the lower right corner of consonants in some Latin transcriptions of various indigenous languages of the Caucasus mountains.
A cedilla, or cedille, is a hook or tail added under certain letters to indicate that their pronunciation is modified. In Catalan, French, and Portuguese it is used only under the letter ⟨c⟩, and the entire letter is called, respectively, c trencada, c cédille, and c cedilhado. It is used to mark vowel nasalization in many languages of Sub-Saharan Africa, including Vute from Cameroon.
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. It was also used in Ossetian before switched back to its Cyrillic counterpart. 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.
A with tilde is a letter of the Latin alphabet formed by addition of the tilde diacritic over the letter A. It is used in Portuguese, Guaraní, Kashubian, Taa, Aromanian, and Vietnamese. In the past, it was also used in Greenlandic.
The orthography of the Old Norse language was diverse, being written in both Runic and Latin alphabets, with many spelling conventions, variant letterforms, and unique letters and signs. In modern times, scholars established a standardized spelling for the language. When Old Norse names are used in texts in other languages, modifications to this spelling are often made. In particular, the names of Old Norse mythological figures often have several different spellings.
A ring diacritic may appear above or below letters. It may be combined with some letters of the extended Latin alphabets in various contexts.
A nasal vowel is a vowel that is produced with a lowering of the soft palate so that the air flow escapes through the nose and the mouth simultaneously, as in the French vowel /ɑ̃/ or Amoy []. By contrast, oral vowels are produced without nasalization.
In phonetics, nasalization is the production of a sound while the velum is lowered, so that some air escapes through the nose during the production of the sound by the mouth. An archetypal nasal sound is.
Little yus and big yus, or jus, are letters of the Cyrillic script representing two Common Slavonic nasal vowels in the early Cyrillic and Glagolitic alphabets. Each can occur in iotated form, formed as ligatures with the decimal i (І). Other yus letters are blended yus (Ꙛ ꙛ), closed little yus (Ꙙ ꙙ) and iotated closed little yus (Ꙝ ꙝ),and iotated blended yus.()
The soft sign is a letter in the Cyrillic script that is used in various Slavic languages. In Old Church Slavonic, it represented a short or reduced front vowel. However, over time, the specific vowel sound it denoted was largely eliminated and merged with other vowel sounds.
The Muscogee language, previously referred to by its exonym, Creek, is a Muskogean language spoken by Muscogee (Creek) and Seminole people, primarily in the US states of Oklahoma and Florida. Along with Mikasuki, when it is spoken by the Seminole, it is known as Seminole.
Ą is a letter in the Polish, Kashubian, Lithuanian, Creek, Navajo, Western Apache, Chiricahua, Osage, Hocąk, Mescalero, Gwich'in, Tutchone, and Elfdalian alphabets. It is formed from the letter a and an ogonek and usually, except in modern Lithuanian and Polish, denotes a nasal a sound.
I with ogonek is a letter of the Latin alphabet formed by addition of the ogonek to the letter I. It is used in Lithuanian, Western Apache, Chipewyan, Mescalero-Chiricahua, Muscogee, Dadibi, Dalecarlian, Gwichʼin, Hän, Iñapari, Kaska, Navajo, Sierra Otomi, Sekani, Tagish, Tlingit, Tutchone, Winnebago, Assiniboine, Mandan, Osage, Tutelo, Catawba, and Ixtlán Zapotec.
U with ogonek is a letter of the Latin alphabet formed by addition of the ogonek to the letter U. It is used in Lithuanian, Chipewyan, Dadibi, Dalecarlian, Gwichʼin, Hän, Iñapari, Kaska, Sierra Otomi, Sekani, Tagish, Tlingit, Tutchone, Winnebago, and Ixtlán Zapotec.
Polish orthography is the system of writing the Polish language. The language is written using the Polish alphabet, which derives from the Latin alphabet, but includes some additional letters with diacritics. The orthography is mostly phonetic, or rather phonemic—the written letters correspond in a consistent manner to the sounds, or rather the phonemes, of spoken Polish. For detailed information about the system of phonemes, see Polish phonology.
Ę is a letter in the Polish, Lithuanian, and Dalecarlian alphabets. It is also used in Navajo to represent the nasal vowel and Kensiu to represent the near-open near-front unrounded vowel. In Latin, Irish, and Old Norse palaeography, it is known as e caudata.
Southern Athabaskan is a subfamily of Athabaskan languages spoken primarily in the Southwestern United States with two outliers in Oklahoma and Texas. The languages are spoken in the northern Mexican states of Sonora, Chihuahua, Coahuila and to a much lesser degree in Durango and Nuevo León. Those languages are spoken by various groups of Apache and Navajo peoples. Elsewhere, Athabaskan is spoken by many indigenous groups of peoples in Alaska, Canada, Oregon and northern California.
