Empty String
In formal language theory, the empty string, or empty word, is the unique String (computer science), string of length zero. Formal theory Formally, a string is a finite, ordered sequence of character (symbol), characters such as letters, digits or spaces. The empty string is the special case where the sequence has length zero, so there are no symbols in the string. There is only one empty string, because two strings are only different if they have different lengths or a different sequence of symbols. In formal treatments, the empty string is denoted with ε or sometimes Λ or λ. The empty string should not be confused with the empty language ∅, which is a formal language (i.e. a set of strings) that contains no strings, not even the empty string. The empty string has several properties: * , ε, = 0. Its string (computer science)#Formal theory, string length is zero. * ε ⋅ s = s ⋅ ε = s. The empty string is the identity element of the concatenation operation. The set of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quotation Mark
Quotation marks are punctuation marks used in pairs in various writing systems to identify direct speech, a quotation, or a phrase. The pair consists of an opening quotation mark and a closing quotation mark, which may or may not be the same glyph. Quotation marks have a variety of forms in different languages and in different media. History The single quotation mark is traced to Ancient Greek practice, adopted and adapted by monastic copyists. Isidore of Seville, in his seventh century encyclopedia, , described their use of the Greek ''diplé'' (a Angle bracket, chevron): The double quotation mark derives from a marginal notation used in fifteenth-century manuscript annotations to indicate a passage of particular importance (not necessarily a quotation); the notation was placed in the outside margin of the page and was repeated alongside each line of the passage. In his edition of the works of Aristotle, which appeared in 1483 or 1484, the Milanese Renaissance humanis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ditto Mark
The ditto mark is a shorthand sign, used mostly in hand-written text, indicating that the words or figures above it are to be repeated. The mark is made using "a pair of apostrophes"; "a pair of marks used underneath a word"; the symbol (quotation mark); but the Cambridge Dictionary of Business English on the same page uses the CJK ditto mark or the symbol (right double quotation mark). In the following example, the second line reads "Blue pens, box of twenty". Black pens, box of twenty ... $2.10 Blue " " " " ... $2.35 History Early evidence of ditto marks can be seen on a cuneiform tablet of the Neo-Assyrian period (934–608 BCE) where two vertical marks are used in a table of synonyms to repeat text. The word ''ditto'' comes from the Tuscan language, where it is the past participle of the verb (to say), with the meaning of "said", as in the locution "the said story". The first recorded use of ''ditto'' with this meaning in English occurs in 1625. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Acute Accent
The double acute accent () is a diacritic mark of the Latin and Cyrillic scripts. It is used primarily in Hungarian or Chuvash, and consequently it is sometimes referred to by typographers as hungarumlaut. The signs formed with a regular umlaut are letters in their own right in the Hungarian alphabet—for instance, they are separate letters for the purpose of collation. Letters with the double acute, however, are considered variants of their equivalents with the umlaut, being thought of as having both an umlaut and an acute accent. Uses Vowel length History Length marks first appeared in Hungarian orthography in the 15th-century Hussite Bible. Initially, only ''á'' and ''é'' were marked, since they are different in quality as well as length. Later ''í'', ''ó'', ''ú'' were marked as well. In the 18th century, before Hungarian orthography became fixed, ''u'' and ''o'' with umlaut + acute (ǘ, ö́) were used in some printed documents. 19th century typographers intr ...

Double Grave Accent
The double grave accent () is a diacritic used in scholarly discussions of the Serbo-Croatian and sometimes Slovene languages. It is also used in the International Phonetic Alphabet. In Serbo-Croatian and Slovenian, double grave accent is used to indicate a short falling tone, though in discussion of Slovenian, a single grave accent is also often used for this purpose. The double grave accent is found in both Latin and Cyrillic; however, it is not used in the everyday orthography of any language, only in discussions of phonology. In the International Phonetic Alphabet, the double grave accent is used to indicate extra-low tone. The letters a, e, i, o, r, u, and their Cyrillic equivalents а, е, и, о, р, and у can all be found with the double grave accent. Unicode provides precomposed characters for the uppercase and the lowercase Latin letters but not the Cyrillic letters. The Cyrillic letters can be formed using the combining character for the double grave, which is loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umlaut Diacritic
Umlaut () is a name for the two dots diacritical mark () as used to indicate in writing (as part of the letters , , and ) the result of the historical sound shift due to which former back vowels are now pronounced as front vowels (for example , , and as , , and ). (The term Germanic umlaut is also used for the underlying historical sound shift process.) In its contemporary printed form, the mark consists of two dots placed over the letter to represent the changed vowel sound. (In some Romance and other languages, the diaeresis diacritic has the same appearance but a different function.) German origin and current usage (literally "changed sound") is the German name of the sound shift phenomenon also known as '' i-mutation''. In German, this term is also used for the corresponding letters ä, ö, and ü (and the diphthong äu) and the sounds that these letters represent. In German, the combination of a letter with the diacritical mark is called , while the marks themselve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
