Circumflex
The circumflex () is a diacritic in the Latin and Greek scripts that is also used in the written forms of many languages and in various romanization and transcription schemes. It received its English name from la, circumflexus "bent around"a translation of the el, περισπωμένη (). The circumflex in the Latin script is chevron-shaped (), while the Greek circumflex may be displayed either like a tilde () or like an inverted breve (). For the most commonly encountered uses of the accent in the Latin alphabet, precomposed characters are available. In English, the circumflex, like other diacritics, is sometimes retained on loanwords that used it in the original language (for example, '' crème brûlée''). In mathematics and statistics, the circumflex diacritic is sometimes used to denote a function and is called a '' hat operator''. A free-standing version of the circumflex symbol, , has become known as '' caret'' and has acquired special uses, particularly in co ...

Diacritic
A diacritic (also diacritical mark, diacritical point, diacritical sign, or accent) is a glyph added to a letter or to a basic glyph. The term derives from the Ancient Greek (, "distinguishing"), from (, "to distinguish"). 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 ( ◌́ ) and grave ( ◌̀ ), 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. The main use of diacritics in Latin script is to change the sound-values of the letters to which they are added. Historically, English has used the diaeresis diacritic to indicate the correct pronunciation of ambiguous words, such as "coöperate", without which the letter sequence could be misinterpreted to be pronounced . Other examples are the acute and grave accents, which can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caret (computing)
Caret is the name used familiarly for the character , provided on most QWERTY keyboards by typing . The symbol has a variety of uses in programming and mathematics. The name "caret" arose from its visual similarity to the original proofreader's caret, a mark used in proofreading to indicate where a punctuation mark, word, or phrase should be inserted into a document. The formal ASCII standard (X3.64.1977) calls it a "circumflex". History Typewriters On typewriters designed for languages that routinely use diacritics (accent marks), there are two possible ways to type these. Keys can be dedicated to precomposed characters (with the diacritic included) or alternatively a dead key mechanism can be provided. With the latter, a mark is made when a dead key is typed but, unlike normal keys, the paper carriage does not move on and thus the next letter to be typed is printed under the accent. The symbol was originally provided in typewriters and computer printers so that circum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Diacritics
Greek orthography has used a variety of diacritics starting in the Hellenistic period. The more complex polytonic orthography ( el, πολυτονικό σύστημα γραφής, translit=polytonikó sýstīma grafī́s), which includes five diacritics, notates Ancient Greek phonology. The simpler monotonic orthography ( el, μονοτονικό σύστημα γραφής, translit=monotonikó sýstīma grafīs), introduced in 1982, corresponds to Modern Greek phonology, and requires only two diacritics. Polytonic orthography () is the standard system for Ancient Greek and Medieval Greek. The acute accent (), the circumflex (), and the grave accent () indicate different kinds of pitch accent. The rough breathing () indicates the presence of the sound before a letter, while the smooth breathing () indicates the absence of . Since in Modern Greek the pitch accent has been replaced by a dynamic accent (stress), and was lost, most polytonic diacritics have no phonetic si ...

Pitch Accent
A pitch-accent language, when spoken, has word accents in which one syllable in a word or morpheme is more prominent than the others, but the accentuated syllable is indicated by a contrasting pitch ( linguistic tone) rather than by loudness (or length), as in many languages, like English. Pitch-accent also contrasts with fully tonal languages like Vietnamese and Standard Chinese, in which each syllable can have an independent tone. Some have claimed that the term "pitch accent" is not coherently defined and that pitch-accent languages are just a sub-category of tonal languages in general. Languages that have been described as pitch-accent languages include: most dialects of Serbo-Croatian, Slovene, Baltic languages, Ancient Greek, Vedic Sanskrit, Tlingit, Turkish, Japanese, Norwegian, Swedish (but not in Finland), Western Basque,Hualde, J.I.

Háček
A caron (), háček or haček (, or ; plural ''háčeks'' or ''háčky'') also known as a hachek, wedge, check, kvačica, strešica, mäkčeň, varnelė, inverted circumflex, inverted hat, flying bird, inverted chevron, is a diacritic mark (◌̌) commonly placed over certain letters in the orthography of some languages to indicate a change of the related letter's pronunciation. The symbol is common in the Baltic, Slavic, Finnic, Samic and Berber languages. The use of the caron differs according to the orthographic rules of a language. In most Slavic and other European languages it indicates present or historical palatalization (e → ě; [] → []), iotation, or postalveolar consonant, postalveolar articulation (c → č; → ). In Salishan languages, it often represents a uvular consonant (x → x̌; [] → ). When placed over vowel symbols, the caron can indicate a contour tone, for instance the falling and then rising tone in the Pinyin romanization of Standard Chi ...

Tilde
The tilde () or , is a grapheme with several uses. The name of the character came into English from Spanish, which in turn came from the Latin '' titulus'', meaning "title" or "superscription". Its primary use is as a diacritic (accent) in combination with a base letter; but for historical reasons, it is also used in standalone form within a variety of contexts. History Use by medieval scribes The tilde was originally written over an omitted letter or several letters as a scribal abbreviation, or "mark of suspension" and "mark of contraction", shown as a straight line when used with capitals. Thus, the commonly used words ''Anno Domini'' were frequently abbreviated to ''Ao Dñi'', with an elevated terminal with a suspension mark placed over the "n". Such a mark could denote the omission of one letter or several letters. This saved on the expense of the scribe's labor and the cost of vellum and ink. Medieval European charters written in Latin are largely made up of such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hat Operator
The hat operator is a mathematical notation with various uses in different branches of science and mathematics. Estimated value In statistics, a circumflex (ˆ), called a "hat", is used to denote an estimator or an estimated value. For example, in the context of errors and residuals, the "hat" over the letter ε indicates an observable estimate (the residuals) of an unobservable quantity called ε (the statistical errors). In simple linear regression with observations of independent variable data x_i and dependent variable data y_i, and assuming a model of y_i = \beta_0+\beta_1 x_i+\varepsilon_i, can lead to an estimated model of the form \hat_i = \hat_0+\hat_1 x_i where \sum_i (y_i-\hat_i)^2 is minimized via least squares by finding optimal values of \hat_0 and \hat_1 for the observed data. Hat matrix In statistics, the hat matrix ''H'' projects the observed values y of response variable to the predicted values ŷ: :\hat = H \mathbf. Cross product In screw theory, one use ...

Grave Accent
The grave accent () ( or ) is a diacritical mark used to varying degrees in French, Dutch, Portuguese, Italian and many other western European languages, as well as for a few unusual uses in English. It is also used in other languages using the Latin alphabet, such as Mohawk and Yoruba, and with non-Latin writing systems such as the Greek and Cyrillic alphabets and the Bopomofo or Zhuyin Fuhao semi-syllabary. It has no single meaning, but can indicate pitch, stress, or other features. For the most commonly encountered uses of the accent in the Latin and Greek alphabets, precomposed characters are available. For less-used and compound diacritics, a combining character facility is available. A free-standing version of the symbol, commonly called a backtick, also exists and has acquired other uses. Uses Pitch The grave accent first appeared in the polytonic orthography of Ancient Greek to mark a lower pitch than the high pitch of the acute accent. In modern practice, ...

Perispomenon
In Ancient Greek grammar, a perispomenon () is a word with a high-low pitch contour on the last syllable, indicated in writing by a circumflex accent mark (). A properispomenon has the same kind of accent, but on the penultimate syllable. Examples: *, ''theoû'', "of a god", is a perispomenon * ''prâxis'' "business" is a properispomenon Etymology ''Peri-spṓmenon'' means "pronounced with a circumflex", the neuter of the present passive participle of ''peri-spáō'' "pronounce with a circumflex" (also "draw off"). ''Pro-peri-spṓmenon'' adds the prefix ''pró'' "before".. is the Greek name for the accent mark ().

Inverted Breve
Inverted breve or arch is a diacritical mark, shaped like the top half of a circle ( ̑ ), that is, like an upside-down breve (˘). It looks similar to the circumflex (ˆ), which has a sharp tip (''Â â Ê ê Î î Ô ô Û û''), while the inverted breve is rounded: (''Ȃ ȃ Ȇ ȇ Ȋ ȋ Ȏ ȏ Ȗ ȗ''). Inverted breve can occur above or below the letter. It is not used in any natural language alphabet, but as a phonetic indicator. It is identical in form to the Ancient Greek circumflex. Uses Serbo-Croatian The inverted breve above is used in traditional Slavicist notation of Serbo-Croatian phonology to indicate long falling accent. It is placed above the syllable nucleus, which can be one of five vowels (ȃ ȇ ȋ ȏ ȗ) or syllabic ȓ. This use of the inverted breve is derived from the Ancient Greek circumflex, which was preserved in the polytonic orthography of Modern Greek and influenced early Serbian Cyrillic printing through religious literature.

Greek Alphabet
The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BCE. It is derived from the earlier Phoenician alphabet, and was the earliest known alphabetic script to have distinct letters for vowels as well as consonants. In Archaic and early Classical times, the Greek alphabet existed in many local variants, but, by the end of the 4th century BCE, the Euclidean alphabet, with 24 letters, ordered from alpha to omega, had become standard and it is this version that is still used for Greek writing today. The uppercase and lowercase forms of the 24 letters are: : , , , , , , , , , , , , , , , , , /ς, , , , , , . The Greek alphabet is the ancestor of the Latin and Cyrillic scripts. Like Latin and Cyrillic, Greek originally had only a single form of each letter; it developed the letter case distinction between uppercase and lowercase in parallel with Latin during the modern era.

Vowel Length
In linguistics, vowel length is the perceived length of a vowel sound: the corresponding physical measurement is duration. In some languages vowel length is an important phonemic factor, meaning vowel length can change the meaning of the word, for example in: Arabic, Estonian, Finnish, Fijian, Kannada, Malayalam, Japanese, Latin, Old English, Scottish Gaelic, and Vietnamese. While vowel length alone does not change word meaning in most dialects of English, it is said to do so in a few dialects, such as Australian English, Lunenburg English, New Zealand English, and South African English. It also plays a lesser phonetic role in Cantonese, unlike in other varieties of Chinese. Many languages do not distinguish vowel length phonemically, meaning that vowel length does not change meaning, and the length of a vowel is conditioned by other factors such as the phonetic characteristics of the sounds around it, for instance whether the vowel is followed by a voiced or a voice ...
