Diacritical use
In languages, the tilde is a diacritical mark (~) placed over a letter to indicate a change in pronunciation, such as nasalization. A diacritic ( also called a diacritic or diacritical mark, point, or sign, is a small sign added to a letter to alter pronunciation A letter is an element in an Alphabetic system of writing such as the Greek alphabet and its descendants In Phonetics, nasalization is the production of a sound while the velum is lowered so that some air escapes through the nose during the production of the sound by
It was first used in the polytonic orthography of Ancient Greek, as a variant of the circumflex accent, representing a rise in pitch followed by a return to standard pitch. The Ancient Greek language is the historical stage in the development of the Hellenic language family spanning the Archaic (c Pitch The circumflex accent was first used in the polytonic orthography of Ancient Greek, where it occurred (subject to certain rules on the accented syllable Pitch accent is a linguistic term of convenience for a variety of restricted tone systems that use variations in pitch to give prominence to a Syllable
Later, it was used to make abbreviations in medieval Latin documents. Scribal abbreviations ( sigla; singular sigil or more rarely siglum) were Abbreviations used by ancient and medieval scribes writing in Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. When an "n" or "m" followed a vowel, it was often omitted, and a tilde (i. e. a small "n") was placed over the preceding vowel to indicate the missing letter. This is the origin of the use of tilde to indicate nasalization. The practice of using the tilde over a vowel to indicate omission of an "n" or "m" continued in printed books in French as a means of reducing text length until the 17th century. French ( français,) is a Romance language spoken around the world by 118 million people as a native language and by about 180 to 260 million people It was also used in Spanish and Portuguese. Portuguese ( or língua portuguesa) is a Romance language that originated in what is now Galicia (Spain and northern Portugal. The tilde was also used occasionally to make other abbreviations, such as over the letter "q" to signify the word que ("what").
The tilded "n" ("ñ") developed from the digraph "nn" in Spanish. It is usually regarded as a separate letter called eñe (IPA ['eɲe]), rather than a letter-diacritic combination. Ñ (lower case ñ) is a letter of the modern Roman alphabet formed by an N with a diacritical Tilde. In addition, the word tilde can refer to any diacritic in this language; for example, the acute accent in José is also called a tilde in Spanish. Current languages in which the tilded "n" ("ñ") is used for the palatal nasal consonant /ɲ/ include:
It is also as a small "n" that the tilde originated when written above another letters, marking a Latin "n" which had been elided in old Galician-Portuguese. The palatal nasal is a type of Consonant, used in some spoken Languages The symbol in the International Phonetic Alphabet that represents this Basque ( native name: euskara) is the Language spoken by the Basque people who inhabit the Pyrenees in North-Central Spain Guaraní /gwaraˈni/ (local name avañe'ẽ) is an indigenous language of South America that belongs to the Tupí-Guaraní subfamily of the Mapudungun (from mapu 'earth land' and dungun 'speak speech' is a Language isolate spoken in central Chile and west central Argentina Tetum (also Tetun) is an Austronesian language, a National language and one of the two Official languages of East Timor. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Elision is the omission of one or more sounds (such as a Vowel, a Consonant, or a whole Syllable) in a word or phrase producing a result that is easier It indicates nasalization of the base vowel: mão "hand", from Lat. manu-; razões "reasons", from Lat. rationes. Current languages and alphabets in which the tilde is used as a sign of nasalization include:
- Portuguese

In Logic and Mathematics, negation or not is an operation on Logical values for example the logical value of a Proposition g. "~p" equals "not p". ) Modern use has been replacing the tilde with the exclamation mark (!) for this purpose, to avoid confusion with equivalence relations. In Mathematics, an equivalence relation is a Binary relation between two elements of a set which groups them together as being "equivalent"
Electronics
It can approximate the sine wave symbol (∿, U+223F), which is used in electronics to indicate alternating current, in place of +, −, or ⎓ for direct current. In Computing, Unicode is an Industry standard allowing Computers to consistently represent and manipulate text expressed in most of the world's Electronics refers to the flow of charge (moving Electrons through Nonmetal conductors (mainly Semiconductors, whereas electrical An alternating current ( AC) is an Electric current whose direction reverses cyclically as opposed to Direct current, whose direction remains constant Direct current ( DC) is the unidirectional flow of Electric charge.
Punctuation
The swung dash is used in various ways in punctuation.
Range
In some languages (though not English), a tilde-like wavy dash may be used as punctuation (instead of an unspaced hyphen or en-dash) between two numbers, to indicate a range rather than subtraction or a hyphenated number (such as a part number or model number). A hyphen ( -) is a Punctuation mark It is used for both Words to join and to separate Syllables It is often confused with the dashes A dash is a Punctuation mark It is longer than a Hyphen and is used differently A number is an Abstract object, tokens of which are Symbols used in Counting and measuring. In Mathematics, an interval is a set of Real numbers with the property that any number that lies between two numbers in the set is also included in the set Subtraction is one of the four basic Arithmetic operations it is the inverse of Addition, meaning that if we start with any number and add any number and then subtract For example, 12~15 means "12 to 15", ~3 means "up to three" and 100~ means "100 and greater. " Japanese and other East Asian languages almost always use this convention, but it is often done for clarity in some other languages as well. is a language spoken by over 130 million people in Japan and in Japanese emigrant communities East Asian languages describe two notional groupings of languages in East and Southeast Asia: Languages which have been greatly influenced by Chinese uses the wavy dash and full-width em dash interchangeably for this purpose. In English, the tilde is often used to express ranges and model numbers in electronics but rarely in formal grammar or type-set documents, as a wavy dash preceding a number sometimes represents an approximation (see the following section). Electronics refers to the flow of charge (moving Electrons through Nonmetal conductors (mainly Semiconductors, whereas electrical
Japanese
The swung dash (波ダッシュ nami dasshu, wave dash) is used for various purposes in Japanese. Japanese punctuation (約物 yakumono) includes various written marks (besides characters and numbers which differ from those found in European languages
In Japanese, the tilde is also used to separate a title and a subtitle in the same line. A colon is usually used in English for this purpose.
When used in conversations via email or instant messenger it might have been intended as a sarcasm mark or, in Asian cultures, as an extension of the final syllable to produce the same effect as "whyyyyyy" with "why~~". A sarcasm mark or sarcasm point identifies text as being Derogatory or ironic. Used at the end of a word or sentence in text communications, it often denotes something said in a sing-song voice, or similar to the use in instant messengers and email, depending on context.
Mathematics
In mathematics, the tilde, sometimes pronounced "twiddle," is often used to denote an equivalence relation between two objects. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and In Mathematics, an equivalence relation is a Binary relation between two elements of a set which groups them together as being "equivalent" Thus "x ~ y" means "x is equivalent to y". (Note that this is usually quite different from stating that x equals y. Equality is the paradigmatic example of the more general concept of Equivalence relations on a set those binary relations which are reflexive, symmetric ) The expression "x ~ y" is sometimes read aloud as "x twiddles y," perhaps as an analogue to the verbal expression of "x = y. "
There are two common contexts in which "~" is used to denote particular equivalence relations: It can be used to denote the asymptotical equality of two functions. In pure and Applied mathematics, particularly the Analysis of algorithms, real analysis and engineering asymptotic analysis is a method of describing For example, f(x) ~ g(x), means that limx→∞ f(x)/g(x) = 1. Additionally, in statistics and probability theory, ~ means "is distributed as. Statistics is a mathematical science pertaining to the collection analysis interpretation or explanation and presentation of Data. Probability theory is the branch of Mathematics concerned with analysis of random phenomena " See random variable. A random variable is a rigorously defined mathematical entity used mainly to describe Chance and Probability in a mathematical way
There is also a triple-tilde (≋), which is often used to show congruence, an equivalence relation in geometry.
A tilde can also be used to represent Similarity. In modern Geometry, polygons can be similar to one another, and similarity can be expressed as e.g. Triangle ABC ~ (is similar to) Triangle DEF. Geometry ( Greek γεωμετρία; geo = earth metria = measure is a part of Mathematics concerned with questions of size shape and relative position C D E A triangle is one of the basic Shapes of Geometry: a Polygon with three corners or vertices and three sides or edges which are Line A triangle is one of the basic Shapes of Geometry: a Polygon with three corners or vertices and three sides or edges which are Line This is often used to relate polygons that have a geometric similarity to others, such as when using ratios and proportions to compare polygons.
In English it is sometimes used to represent approximation, for example ~10 would mean "approximately 10. English is a West Germanic language originating in England and is the First language for most people in the United Kingdom, the United States An approximation (represented by the symbol ≈ is an inexact representation of something that is still close enough to be useful " Similar symbols are used in mathematics, such as in π ≈ 3. 14, "π is about equal to 3. IMPORTANT NOTICE Please note that Wikipedia is not a database to store the millions of digits of π please refrain from adding those to Wikipedia as it could cause technical problems 14. " Since the double-tilde (≈) is not available from the keyboard except on the Macintosh (where it is Option-x on English layouts), the tilde (~) became a substitute for use in typed entry. An approximation (represented by the symbol ≈ is an inexact representation of something that is still close enough to be useful In Computing, a keyboard is an Input device partially modelled after the typewriter keyboard which uses an arrangement of buttons or keys Macintosh, commonly nicknamed Mac is a Brand name which covers several lines of Personal computers designed developed and marketed by Apple Inc QWERTY keyboardjpg|thumb|right|300px|QWERTY keyboard on a Laptop of 2007]]A keyboard layout is any specific mechanical, visual, or functional Typing is the process of inputting text into a device such as a Typewriter, Computer, or a Calculator, by pressing keys on a keyboard.
A tilde is also used to indicate "approximately equal to" (e. g. 1. 902 ~= 2). This usage probably developed as a typed alternative to the libra symbol used for the same purpose in written mathematics, which is an equal sign (=) with the upper bar replaced by a bar with an upward hump or loop in the middle or, sometimes, a tilde. [Also see Approximation]. An approximation (represented by the symbol ≈ is an inexact representation of something that is still close enough to be useful The symbol "≈" is also used for this purpose.
A tilde can be used on its own between two expressions (e. g. a ~ 0. 1) to state that the two are of the same order of magnitude. An order of magnitude is the class of scale or magnitude of any amount where each class contains values of a fixed ratio to the class preceding it
A tilde placed below a letter in mathematics can represent a vector quantity.
Computing
Directories and URLs
In Unix shells, the tilde indicates the current user's home directory (e. A Unix shell, is a command line shell that provides the traditional User interface for the Unix Operating system and for Unix-like In computing a home directory is a file system directory which contains the personal files of a given user of the system g. , /home/username). When prepended to a particular username, it indicates that user's home directory (e. g. , ~janedoe for the home directory of user janedoe, typically /home/janedoe). When some Unix shell commands overwrite a file, they can be made to keep a backup by renaming the original file as filename~.
Used in URLs on the World Wide Web, it often denotes a personal website on a Unix-based server. Uniform Resource Locator is an URI which also specifies where the identified resource is available and the protocol for retrieving it The World Wide Web (commonly shortened to the Web) is a system of interlinked Hypertext documents accessed via the Internet. Unix (officially trademarked as UNIX, sometimes also written as Unix with Small caps) is a computer For example, http://www. example. com/~johndoe/ might be the personal web site of John Doe. This mimics the Unix shell usage of the tilde. However, when accessed from the web, file access is usually directed to a subdirectory in the user's home directory, such as /home/username/public_html or /home/username/www. In Computing, a directory, catalog, folder or drawer is an entity in a File system, which contains a group of files and/or other directories
In URLs, the characters %7E (or %7e) may substitute a tilde if an input device lacks a tilde key. Thus, http://www. example. com/~johndoe/ and http://www. example. com/%7Ejohndoe/ are essentially the same URL.
Computer languages
The tilde is used in the Awk programming language as part of the pattern match operators for regular expressions:
variable ~ /regex/returns true if the variable is matched. AWK is a general purpose Programming language that is designed for processing text-based data either in files or data streams and was created at Bell Labs in the 1970s A programming language is an Artificial language that can be used to write programs which control the behavior of a machine particularly a Computer. In Computing, regular expressions provide a concise and flexible means for identifying strings of text of interest such as particular characters words or patterns of charactersvariable !~ /regex/returns false if the variable is matched.
A variant of this, with the plain tilde replaced with =~, was adopted in Perl, and this semi-standardization has led to the use of these operators in other programming languages, such as Ruby or the SQL variant of the database PostgreSQL. NOTES FOR EDITORS "Perl" is not an acronym (read the "Name" section below Ruby is a dynamic, reflective, general purpose Object-oriented programming language that combines syntax inspired by Perl with Smalltalk PostgreSQL is an Object-relational database management system (ORDBMS

In "text mode" of the LaTeX typesetting language a stand-alone tilde can be obtained with \~{} and for use as a diacritics, e. LaTeX (ˈleɪtɛ g. , like \~{n} rendering "ñ". In "math mode" a stand-alone tilde can be written as \tilde{~} and as diacritics, e. g. , \tilde{x}. For a wider tilde the \widetilde can be used. The \sim command produce a tilde-like character that is often used in probability mathematical equations, and the double-tilde is obtained with \approx. Probability is the likelihood or chance that something is the case or will happen An equation is a mathematical statement, in symbols, that two things are exactly the same (or equivalent In both text and math mode a tilde on its own (~) is rendering a white space with no line breaking.

Microsoft filenames
The tilde was part of Microsoft's filename mangling scheme when it developed the VFAT file system. Microsoft Corporation is an American multinational Computer technology Corporation, which rose to dominate the Home computer The process of name mangling, in Computing, involves a re-writing of the file name for compatibility at the Operating system level Templateinfobox filesystem whilst covering all 3 file systems please make any style changes to both at the same time This upgrade introduced long filenames to Microsoft Windows, and permitted additional characters (such as the space) to be part of filenames, which were prohibited in previous versions. Microsoft Windows is a series of Software Operating systems and Graphical user interfaces produced by Microsoft. Programs written prior to this development could only access filenames in the so-called 8. 3 format—the filenames consisted of a maximum of eight alphanumeric characters, followed by a period, followed by three more alphanumeric characters. In order to permit these legacy programs to access files in the VFAT file system, each file had to be given two names—one long, more descriptive one, and one that conformed to the 8. 3 format. This was accomplished with a name-mangling scheme in which the first six characters of the filename are followed by a tilde and a digit. For example, "Program Files" becomes "PROGRA~1".
Also, the tilde symbol is used to prefix hidden temporary files that are created when a document is opened in Windows. For example, when you open a Word document called "Document1. doc," a file called "~ocument1. doc" will be created in the same directory. This file contains information about which user has the file open, to prevent multiple users from attempting to change a document at the same time.
Games
In many games, the tilde key is used to open the developer console. This is evident in games such as Quake, Half-Life 2, and Unreal. Quake is a First-person shooter Computer game that was released by Id Software on June 22, 1996. Half-Life 2 is a Science fiction First-person shooter computer game and the sequel to the highly acclaimed Half-Life Unreal is a First-person shooter Computer game developed by Epic Games and Digital Extremes and published by GT Interactive
Other uses
Computer programmers use the tilde in various ways and often call the symbol (as opposed to the diacritic) a squiggle or a twiddle. A programmer is someone who writes Computer software. The term computer programmer can refer to a specialist in one area of computer programming or to a generalist According to the Jargon File, other synonyms sometimes used in programming include not, approx, wiggle, enyay (after eñe) and (humorously) sqiggle (pronounced /ˈskɪɡəl/). The Jargon File is a Glossary of hacker Slang. The original Jargon File was a collection of hacker slang from technical cultures such as the MIT AI Ñ (lower case ñ) is a letter of the modern Roman alphabet formed by an N with a diacritical Tilde.
In Google search, the tilde entered before a search query word displays listings with that word and synonyms of it. Google search is a Web search engine owned by Google Inc, and it is the most used search engine on the Web. [2]
In MediaWiki, three consecutive tildes (~~~) create a "signature" (which can be customised by the user), five consecutive tildes (~~~~~) result the time in UTC, and four consecutive tildes (~~~~) result in signature followed by the time in UTC. MediaWiki is a web-based Wiki software application used by all projects of the Wikimedia Foundation, all wikis hosted by Wikia, and
Another recent use of the tilde is to indicate either a "melodic" pronunciation, or a commonly recognized vocal inflection by enclosing a word or entire phrase between a pair of tilde (similar to the use of quotation marks) which indicates that such word or phrase is to be either sung as a tune, ~Happy birthday to you. . . ~, pronounced as a jeer or taunt, ~Nyah, nyah!~, or with a common change in pitch, ~What-EVER!~.
Juggling notation
In the juggling notation system beatmap, tilde can be added to either "hand" in a pair of fields to say "cross the arms with this hand on top". Juggling is a physical human skill involving the movement of objects usually through the air for entertainment (see Object manipulation) Mills Mess is thus represented as (~2x,1)(1,2x)(2x,~1)*. In Juggling, the Mills Mess is a popular Toss juggling pattern typically performed with three Balls although the number and objects can be different [3]
