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 computing ...

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 Since in Modern Greek the pitch accent has been replaced by a dynamic accent (stress), and was lost, most polytonic diacritics have no phonetic si ...

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 Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the ... 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 p ... [...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 circumfle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acute Accent
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. Uses History An early precursor of the acute accent was the apex, used in Latin inscriptions to mark long vowels. Pitch Ancient Greek The acute accent was first used in the polytonic orthography of Ancient Greek, where it indicated a syllable with a high pitch. In Modern Greek, a stress accent has replaced the pitch accent, and the acute marks the stressed syllable of a word. The Greek name of the accented syllable was and is (''oxeîa'', Modern Greek ''oxía'') "sharp" or "high", which was calqued (loan-translated) into Latin as "sharpened". Stress The acute accent marks the stressed vowel of a word in several languages: * Blackfoot uses acute accents to show the place of stress in a word: soyópokists ...

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 Ch ...

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 voiceless conso ...

Syllable
A syllable is a unit of organization for a sequence of speech sounds typically made up of a syllable nucleus (most often a vowel) with optional initial and final margins (typically, consonants). Syllables are often considered the phonological "building blocks" of words. They can influence the rhythm of a language, its prosody, its poetic metre and its stress patterns. Speech can usually be divided up into a whole number of syllables: for example, the word ''ignite'' is made of two syllables: ''ig'' and ''nite''. Syllabic writing began several hundred years before the first letters. The earliest recorded syllables are on tablets written around 2800 BC in the Sumerian city of Ur. This shift from pictograms to syllables has been called "the most important advance in the history of writing". A word that consists of a single syllable (like English ''dog'') is called a monosyllable (and is said to be ''monosyllabic''). Similar terms include disyllable (and ''disyllabic''; also '' ...

Perispomenon
In Ancient Greek Ancient Greek grammar, grammar, a perispomenon () is a word with a high-low Ancient Greek accent, 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 grammatical gender, neuter of the present tense, present passive voice, 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 ().

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?''

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 ab ... [...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 ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
