Apostrophe
The apostrophe ( or ) is a punctuation mark, and sometimes a diacritical mark, in languages that use the Latin alphabet and some other alphabets. In English, the apostrophe is used for two basic purposes: * The marking of the omission of one or more letters, e.g. the contraction of "do not" to "don't". * The marking of possessive case of nouns (as in "the eagle's feathers", "in one month's time", "at your parents' ome). The word "apostrophe" comes ultimately from Greek (, ' he accent ofturning away or elision'), through Latin and French. For use in computer systems, Unicode has code points for three different forms of apostrophe. Usage in English Historical development The apostrophe was first used by Pietro Bembo in his edition of '' De Aetna'' (1496). It was introduced into English in the 16th century in imitation of French practice. French practice Introduced by Geoffroy Tory (1529), the apostrophe was used in place of a vowel letter to indicate elision (as ...

French Articles And Determiners
In French, articles and determiners are required on almost every common noun, much more so than in English. They are inflected to agree in gender (masculine or feminine) and number (singular or plural) with the noun they determine, though most have only one plural form (for masculine and feminine). Many also often change pronunciation when the word that follows them begins with a vowel sound. While articles are actually a subclass of determiners (and in traditional grammars most French determiners are in turn a subclass of adjectives), they are generally treated separately; thus, they are treated separately here as well. Articles French has three articles: a definite article, corresponding in many cases to English ''the''; an indefinite article, corresponding to English ''a/an''; and a partitive article, used roughly like ''some'' in English. Definite article The French definite article derives from a Latin distal demonstrative, ''ille''. It evolved from the Old French article ...

Modifier Letter Apostrophe
The modifier letter apostrophe is a letter in Unicode encoding, used primarily for various glottal sounds. Encoding The letter apostrophe is encoded at , which is in the ''Spacing Modifier Letters'' Unicode block. In Unicode code charts it looks identical to the , but this is not true for all fonts. The primary difference between the letter apostrophe and U+2019 is that the letter apostrophe U+02BC has the Unicode General Category "Letter, modifier" (Lm), while U+2019 has the category "Punctuation, Final quote" (Pf). In early Unicode (versions 1.0–2.1.9) U+02BC was preferred for the punctuation apostrophe in English. Since version 3.0.0, however, U+2019 is preferred, because it is defined as a punctuation mark. The behavior of Unicode letters and punctuation marks differs, causing complications if punctuation code points are used for letters or vice versa. Use In the International Phonetic Alphabet, it is used to express ejective consonants, such as , . It denotes a glo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palatalised Consonant
In phonetics, palatalization (, also ) or palatization is a way of pronouncing a consonant in which part of the tongue is moved close to the hard palate. Consonants pronounced this way are said to be palatalized and are transcribed in the International Phonetic Alphabet by affixing the letter ⟨ʲ⟩ to the base consonant. Palatalization cannot minimally distinguish words in most dialects of English, but it may do so in languages such as Russian, Mandarin, and Irish. Types In technical terms, palatalization refers to the secondary articulation of consonants by which the body of the tongue is raised toward the hard palate and the alveolar ridge during the articulation of the consonant. Such consonants are phonetically palatalized. "Pure" palatalization is a modification to the articulation of a consonant, where the middle of the tongue is raised, and nothing else. It may produce a laminal articulation of otherwise apical consonants such as and . Phonetically palatalized consonan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prime (symbol)
The prime symbol , double prime symbol , triple prime symbol , and quadruple prime symbol are used to designate units and for other purposes in mathematics, science, linguistics and music. Although the characters differ little in appearance from those of the apostrophe and single and double quotation marks, the uses of the prime symbol are quite different. While an apostrophe is now often used in place of the prime, and a double quote in place of the double prime (due to the lack of prime symbols on everyday writing keyboards), such substitutions are not considered appropriate in formal materials or in typesetting. Designation of units The prime symbol is commonly used to represent feet (ft), and the double prime is used to represent inches (in). The triple prime as used in watchmaking represents a ( of a ''French'' inch or '' pouce'', about ). Primes are also used for angles. The prime symbol is used for arcminutes ( of a degree), and the double prime for arcsecond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D-prime
The sensitivity index or discriminability index or detectability index is a dimensionless statistic used in signal detection theory. A higher index indicates that the signal can be more readily detected. Definition The discriminability index is the separation between the means of two distributions (typically the signal and the noise distributions), in units of the standard deviation. Equal variances/covariances For two univariate distributions a and b with the same standard deviation, it is denoted by d' ('dee-prime'): : d' = \frac. In higher dimensions, i.e. with two multivariate distributions with the same variance-covariance matrix \mathbf, (whose symmetric square-root, the standard deviation matrix, is \mathbf), this generalizes to the Mahalanobis distance between the two distributions: : d'=\sqrt = \lVert \mathbf^(\boldsymbol_a-\boldsymbol_b) \rVert = \lVert \boldsymbol_a-\boldsymbol_b \rVert /\sigma_, where \sigma_ = 1/ \lVert\mathbf^\boldsymbol\rVert is the 1d slice of the ...
