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 "bent around"a translation of the (). 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 '' entrepôt, 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, , is encoded in ASCII and Unicode and has become known as '' caret'' and has acquired special uses, particularly i ...

Greek Diacritics
Greek orthography has used a variety of diacritics starting in the Hellenistic period. The more complex polytonic orthography (), which includes five diacritics, notates Ancient Greek phonology. The simpler monotonic orthography (), 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 and includes: * acute accent () * circumflex accent () * grave accent (); these 3 accents indicate different kinds of pitch accent * rough breathing () indicates the presence of the sound before a letter * smooth breathing () indicates the absence of . Since in Modern Greek the pitch accent has been replaced by a stress (linguistics), dynamic accent (stress), and was lost, most polytonic diacritics have no phonetic significance, and merely reveal the underlying Ancient Greek etymology. Monotonic orthography () is the standard system for Modern Greek. It retains two dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caret (proofreading)
The caret () is a V-shaped grapheme, usually inverted and sometimes extended, used in proofreading and typography to indicate that additional material needs to be inserted at the point indicated in the text. The same symbol is also used as a diacritical mark modifying another character (as in ), for which purpose it is known as a circumflex. Usage The caret was originally and continues to be used in handwritten form as a proofreading mark to indicate where a punctuation mark, word, or phrase should be inserted into a document. The term comes from the Latin word , "it lacks", from , "to lack; to be separated from; to be free from". The caret symbol can be written just below the line of text for a punctuation mark at low line position, such as a comma, or just above the line of text as an inverted caret () for a character at a higher line position, such as an apostrophe The apostrophe (, ) is a punctuation mark, and sometimes a diacritical mark, in languages that use the L ...

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 ASCII standard (X3.64.1977) calls it a "circumflex"; the Unicode standard calls it a "circumflex accent", although it is no longer practicable for that purpose. 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); 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 ...

Háček
A caron or háček ( ), is a diacritic mark () placed over certain letters in the orthography of some languages, to indicate a change of the related letter's pronunciation. Typographers tend to use the term ''caron'', while linguists prefer the Czech word '. The symbol is common in the Baltic, Slavic, Finnic, Samic and Berber language families. Its use 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 Chinese, Mandarin Chinese. It is also used to decorate symbols in mathematics, where it is often pronounced ("check"). The caro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 , grave , and circumflex (all shown above an 'o'), 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 indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tilde
The tilde (, also ) is a grapheme or with a number of uses. The name of the character came into English from Spanish , which in turn came from the Latin , meaning 'title' or 'superscription'. Its primary use is as a diacritic (accent) in combination with a base letter. Its freestanding form is used in modern texts mainly to indicate approximation. History Use by medieval scribes The tilde was originally one of a variety of marks written over an omitted letter or several letters as a scribal abbreviation (a "mark of contraction"). Thus, the commonly used words ''Anno Domini'' were frequently abbreviated to ''Ao Dñi'', with an elevated terminal with a contraction 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 abbreviated words with contraction marks and other abbreviations ...

Vowel Length
In linguistics, vowel length is the perceived or actual length (phonetics), duration of a vowel sound when pronounced. Vowels perceived as shorter are often called short vowels and those perceived as longer called long vowels. On one hand, many languages do not distinguish vowel length phoneme, phonemically, meaning that vowel length alone does not change the meanings of words. However, the amount of time a vowel is uttered can change based on factors such as the phonetic characteristics of the sounds around it: the phonetic environment. An example is that vowels tend to be pronounced longer before a voiced consonant and shorter before a voiceless consonant in the standard accents of General American English, American and Received Pronunciation, British English. On the other hand, vowel length is indeed an important phonemic factor in certain languages, meaning vowel length can change word-meanings, for example in Arabic phonology#Vowels, Arabic, Czech phonology, Czech, Dravidia ...

Hat Operator
A "hat" (circumflex (ˆ)), placed over a symbol is a mathematical notation with various uses. 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 \hat indicates an observable estimate (the residuals) of an unobservable quantity called \varepsilon (the statistical errors). Another example of the hat denoting an estimator occurs in simple linear regression. Assuming a model of y_i = \beta_0+\beta_1 x_i+\varepsilon_i, with observations of independent variable data x_i and dependent variable data y_i, the estimated model is of the form \hat_i = \hat_0+\hat_1 x_i where \sum_i (y_i-\hat_i)^2 is commonly 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 ...

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 tilde diacritic () or an inverted breve accent mark () in native transcriptions with the Greek alphabet, or by a circumflex accent mark () in transcriptions with the Latin alphabet. 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".. , ''perispomeni'', is the Greek name for the accent marks ( or ) used above Greek letters, also known as , ''oxýbarys'', "high-low" or "acute-grave", and its original form as a circumflex accent () was combining the acute () and grave ...

Chevron (insignia)
A chevron (also spelled cheveron, especially in older documents) is a V-shaped mark or symbol, often inverted. The word is usually used in reference to a kind of fret in architecture, or to a badge or insignia used in military or police uniforms to indicate rank or length of service, or in heraldry and the designs of flags (see flag terminology). Ancient history Appearing on pottery and petrographs throughout the ancient world, the chevron can be considered to be one of the oldest symbols in human history, with V-shaped markings occurring as early as the Neolithic era (6th to 5th millennia BC) as part of the Vinča symbols inventory. The Vinča culture responsible for the symbols appear to have used the chevron as part of a larger proto-writing system rather than any sort of heraldic or decorative use, and are not known to have passed the symbol on to any subsequent cultures.Mäder, Michael: ''Ist die Donauschrift Schrift?''

Mathematics
Mathematics is a field of study that discovers and organizes methods, Mathematical theory, theories and theorems that are developed and Mathematical proof, proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), Mathematical analysis, analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of mathematical object, abstract objects that consist of either abstraction (mathematics), abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to proof (mathematics), prove properties of objects, a ''proof'' consisting of a succession of applications of in ...

Bamanankan Language
Bambara, also known as Bamana (N'Ko script: ) or Bamanankan (N'Ko script: ; Arabic script: ), is a lingua franca and national language of Mali spoken by perhaps 14 million people, natively by 4.2 million Bambara people and about 10 million Second language, second-language users. It is estimated that about 80 percent of the population of Mali speak Bambara as a first or second language. It has a subject–object–verb clause structure and two lexical tones. Classification Bambara is a variety of a group of closely related languages called Manding languages, Manding, whose native speakers trace their cultural history to the medieval Mali Empire. Varieties of Manding are generally considered (among native speakers) to be mutually intelligible – dependent on exposure or familiarity with dialects between speakers – and spoken by 9.1 million people in the countries Burkina Faso, Senegal, Guinea-Bissau, Guinea, Liberia, Ivory Coast and the Gambia.
