The tilde ( tilde in the American Heritage dictionary or ; ˜ or ~)Several more or less common informal names are used for the tilde that usually describe the shape, including squiggly, squiggle(s), and flourish. is a with several uses. The name of the character came into English from and from Portuguese, which in turn came from the , meaning "title" or "superscription".

The reason for the name was that it was originally written over a letter as a scribal abbreviation, as a "mark of suspension", shown as a straight line when used with capitals. Thus the commonly used words were frequently abbreviated to Ao Dñi, 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 labour and the cost of vellum and ink. Medieval European charters written in Latin are largely made up of such abbreviated words with suspension marks and other abbreviations; only uncommon words were given in full. The tilde has since been applied to a number of other uses as a mark or a character in its own right. These are encoded in at and , and there are additional similar characters for different roles. In , the latter kind of tilde and the (⁓) are used in dictionaries to indicate the omission of the entry word.


Common use
This symbol (in English) informally means , "about", or "around", such as "~30 minutes before", meaning " approximately 30 minutes before". It can mean "similar to", including "of the same order of magnitude as", such as: "" meaning that and are of the same order of magnitude. Another approximation symbol is the double-tilde ≈, meaning "approximately equal to", the critical difference being the subjective level of accuracy: ≈ indicates a value which can be considered functionally equivalent for a calculation within an acceptable degree of error, whereas ~ is usually used to indicate a larger, possibly significant, degree of error. The tilde is also used to indicate "equal to" or "approximately equal to" by placing it over the "=" symbol, like so: .


History

Use by medieval scribes
The text of the of 1086, relating for example, to the manor of Molland in (see image left), is highly abbreviated as indicated by numerous tildes. The text with abbreviations expanded is as follows:


Role of mechanical typewriters
The incorporation of the tilde (~) into is a direct result of its appearance as a distinct character on mechanical in the late nineteenth century. When all were pieces of metal permanently installed, and number of characters much more limited than in , the question of which languages and markets required which characters was an important one. Any good typewriter store had a catalog of alternative keyboards that could be specified for machines ordered from the factory.

At that time, the tilde was used only in Spanish and Portuguese typewriters (keyboards). In Modern Spanish, the tilde is used only with n and N. Both were conveniently assigned to a single mechanical typebar, which sacrificed a key that was felt to be less important, usually the ½—¼ key.

Portuguese, however, uses not ñ but nh. It uses the tilde on the vowels a and o. So as not to sacrifice two of the tightly limited keys to ã Ã õ Õ, the decision was made to make the ~ a separate "dead" character in which the carriage holding the paper did not move. , which had a notch cut out to avoid hitting a mechanical linkage that triggered carriage movement, were used for characters that were intended to be combined (overstruck).

On mechanical typewriters, Spanish keyboards (the first, or one of the first, non-English keyboards) had a dead key, which contained the (´), used over any vowel, and the dieresis (¨), used only over u. It was a simple matter to create a dead key for a Portuguese keyboard (created later than the Spanish one) to be overstruck with a and o and so the ~ was born as a typographical character, which did not exist previously as a type or printing character. That was probably a product of the first and leading manufacturer of (mechanical) typewriters, Remington.


Connection to Spanish
As indicated by the etymological origin of the word "tilde" in English, this symbol has been closely associated with the . The connection stems from the use of the tilde above the letter "n" to form "ñ" in Spanish, a feature shared by only a few other languages, all historically connected to Spanish. This peculiarity can help non-native speakers quickly identify a text as being written in Spanish with little chance of error. In addition, most native speakers, although not all, use the word "espa ñol" to refer to their language. Particularly during the 1990s, Spanish-speaking intellectuals and news outlets demonstrated support for the language and the culture by defending this letter against and trends that threatened to remove it from keyboards and other standardised products and codes. The Instituto Cervantes, founded by Spain's government to promote the Spanish language internationally, chose as its logo a highly stylised Ñ with a large tilde. The 24-hour news channel in the US later adopted a similar strategy on its existing logo for the launch of its Spanish-language version. And similarly to the National Basketball Association (NBA), the Spain men's national basketball team is nicknamed ÑBA.

Confusingly, in Spanish itself the word tilde is used more generally for diacritics, including the stress-marking acute accent. Diccionario de la lengua española, Real Academia Española The diacritic ~ is more commonly called la virgulilla or la tilde de la eñe, and is not considered an accent mark in Spanish, but rather simply a part of the letter ñ (much like ).


Diacritical use
In some languages, the tilde is used as a mark (  ˜ ) placed over a letter to indicate a change in pronunciation, such as .


Pitch
It was first used in the of , as a variant of the , representing a rise in followed by a return to standard pitch.


Abbreviation
Later, it was used to make abbreviations in medieval documents. When an or followed a vowel, it was often omitted, and a tilde (i.e., a small ) was placed over the preceding vowel to indicate the missing letter; this is the origin of the use of tilde to indicate nasalization (compare the development of the umlaut as an abbreviation of .) The practice of using the tilde over a vowel to indicate omission of an or continued in printed books in as a means of reducing text length until the 17th century. It was also used in Portuguese, and .

The tilde was also used occasionally to make other abbreviations, such as over the letter ("") to signify the word que ("that").


Nasalization
It is also as a small that the tilde originated when written above other letters, marking a which had been in old Galician-Portuguese. In modern Portuguese it indicates of the base vowel: mão "hand", from Lat. manu-; razões "reasons", from Lat. rationes. This usage has been adopted in the orthographies of several native languages of South America, such as and Nheengatu, as well as in the International Phonetic Alphabet (IPA) and many other phonetic alphabets. For example, is the IPA transcription of the pronunciation of the French place-name .

In , the symbol after a vowel means that the letter serves only to give the vowel a nasalised pronunciation, without being itself pronounced, as it normally is. For example, gives the pronunciation whereas gives .


Palatal n
The tilded (, ) developed from the digraph in Spanish. In this language, is considered a separate letter called eñe (), rather than a letter-diacritic combination; it is placed in Spanish dictionaries between the letters and . In Spanish the word tilde can refer to diacritics in general, e.g. the acute accent in José,
(2018). 9788467034264, Real Academia Española.
and the diacritic in can also be called "virgulilla". Current languages in which the tilded () is used for the consonant include:


Tone
In Vietnamese, a tilde over a vowel represents a creaky rising tone ( ngã).


International Phonetic Alphabet
In , a tilde is used as a above a letter, below it or onto the middle of it:

  • A tilde above a letter indicates , e.g. .
  • A tilde superimposed onto the middle of a letter indicates or pharyngealization, e.g. . If no precomposed character exists, the Unicode character can be used to generate one.
  • A tilde below a letter indicates , e.g. . If no precomposed Unicode character exists, the Unicode character can be used to generate one.


Letter extension
In Estonian, the symbol stands for the close-mid back unrounded vowel, and it is considered an independent letter.


Other uses
Some languages and alphabets use the tilde for other purposes:
  • : A symbol resembling the tilde () is used over the letter () to become , denoting a long sound ().
  • Guaraní: The tilded (note that with tilde is not available as a precomposed glyph in ) stands for the consonant. Also, the tilded () stands for the nasalized upper central rounded vowel . A small number of other alphabets also use .
  • : A tilde (~) under the letter represents a sound, transliterated as ch or č. (1888). Syrische Grammatik mit Litteratur, Chrestomathie und Glossar. Berlin: H. Reuther's Verlagsbuchhandlung. translated.
  • Estonian uses the tilde above the letter o ( õ) to indicate the vowel , a rare sound among languages.
  • has a combining vertical tilde character: . It is used to indicate in linguistic transcription of certain dialects of the Lithuanian language.Lithuanian Standards Board (LST), proposal for a zigzag diacritic

Most modern proportional fonts align plain spacing tilde at the same level as , or only slightly upper. This distinguishes it from a small tilde ( ˜ ), which is always raised. But in some , especially used in text user interfaces, tilde character is raised too. This apparently is a legacy of , where pairs of similar spacing and combining characters relied on one glyph. Even in ' age character repertoires were often not large enough to distinguish between plain tilde, small tilde and combining tilde. Overprinting of a letter by the tilde was a working method of combining a letter.


Punctuation
The tilde (~) is used in various ways in punctuation:


Range
In some languages (though not generally in English), a tilde-like wavy dash may be used as (instead of an unspaced , or ) between two , to indicate a range rather than or a hyphenated number (such as a part number or model number). 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. 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 , but rarely in formal grammar or in type-set documents, as a wavy dash preceding a number sometimes represents an approximation (see below).


Approximation
Before a number the tilde can mean "approximately"; "~42" means "approximately 42".


Japanese
The nami dasshu is used for various purposes in Japanese, including to denote ranges of numbers, in place of dashes or brackets, and to indicate origin. The wave dash is also used to separate a title and a subtitle in the same line, as a colon is used in English.

When used in conversations via email or instant messenger it may be used as a .

The sign is used as a replacement for the chouon, katakana character, in Japanese, extending the final syllable.


Unicode and Shift JIS encoding of wave dash
In practice the zenkaku chiruda, Unicode U+FF5E, is often used instead of the nami dasshu, Unicode U+301C, because the code for the wave dash, 0x8160, which is supposed to be mapped to U+301C,.. is instead mapped to U+FF5E in Windows code page 932 ('s for Japanese), a widely used extension of Shift JIS.

This avoided a shape definition error in the Unicode code charts: the wave dash reference glyph in JIS / Shift JIS matches the Unicode reference glyph for U+FF5E,. while the reference glyph for U+301C. was reflected, incorrectly, when Unicode imported the JIS wave dash. In other platforms such as the classic Mac OS and , 0x8160 is correctly mapped to U+301C. It is generally difficult, if not impossible, for users of Japanese Windows to type U+301C, especially in legacy, non-Unicode applications.

A similar situation exists regarding the Korean KS X 1001 character set, in which Microsoft maps the or UHC code for the wave dash (0xA1AD) to U+223C (Tilde Operator), while and Apple map it to U+301C.

The current Unicode reference glyph for U+301C has been corrected to match the JIS standard in response to a 2014 proposal, which noted that while the existing Unicode reference glyph had been matched by fonts from the discontinued , all other major platforms including later versions of Microsoft Windows matched the JIS reference glyph for U+301C.

The JIS / Shift JIS wave dash is still formally mapped to U+301C as of JIS X 0213, whereas the Encoding Standard used by HTML5 follows Microsoft in mapping 0x8160 to U+FF5E. These two code points have a similar or identical glyph in several fonts, reducing the confusion and incompatibility.


Mathematics

As a unary operator
A tilde in front of a single quantity can mean "approximately", "about" or "of the same order of magnitude as."

In written mathematical logic, the tilde represents : "~ p" means "not p", where " p" is a . Modern use often replaces the tilde with the negation symbol (¬) for this purpose, to avoid confusion with equivalence relations.


As a relational operator
In , the tilde operator (Unicode U+223C), sometimes called "twiddle", is often used to denote an equivalence relation between two objects. Thus "" means " is equivalent to ". It is a weaker statement than stating that equals . The expression "" is sometimes read aloud as " twiddles ", perhaps as an analogue to the verbal expression of ""..

The tilde can indicate approximate equality in a variety of ways. It can be used to denote the asymptotic equality of two functions. For example, means that .

A tilde is also used to indicate " equal to" (e.g. 1.902 ~= 2). This usage probably developed as a typed alternative to the 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, bump, ︎or loop in the middle (︍︍♎︎) or, sometimes, a tilde (≃). The symbol "≈" is also used for this purpose.︎

In and , a tilde can be used between two expressions (e.g. ) to state that the two are of the same order of magnitude.

In and probability theory, the tilde means "is distributed as"; see .

A tilde can also be used to represent geometric similarity (e.g. , meaning is similar to ). A triple tilde ( ) is often used to show congruence, an equivalence relation in geometry.


As an accent
The symbol "\tilde{f}" is pronounced as "eff tilde" or, informally, as "eff twiddle" or, in American English, "eff wiggle".

This can be used to denote the Fourier transform of f, or a lift of f, and can have a variety of other meanings depending on the context.

A tilde placed below a letter in mathematics can represent a quantity (e.g. (x_1, x_2, x_3, \ldots, x_n) = \underset{^\sim}{\mathbf x}).

In and probability theory, a tilde placed on top of a variable is sometimes used to represent the of that variable; thus \tilde{\mathbf y} would indicate the median of the variable \mathbf y. A tilde over the letter n (\tilde{n}) is sometimes used to indicate the .


Physics
Often in physics, one can consider an equilibrium solution to an equation, and then a perturbation to that equilibrium. For the variables in the original equation (for instance X) a substitution X\to x+\tilde{x} can be made, where x is the equilibrium part and \tilde{x} is the perturbed part.

A tilde is also used in to denote the hypothetical partner. For example, an is referred to by the letter e, and its the selectron is written .


Economics
For relations involving preference, sometimes use the tilde to represent indifference between two or more bundles of goods. For example, to say that a consumer is indifferent between bundles x and y, an economist would write x ~ y.


Electronics
It can approximate the sine wave symbol (∿, 223F), which is used in to indicate alternating current, in place of +, −, or ⎓ for .


Computing

Directories and URLs
On -like (including , , and ), tilde normally indicates the current user's . For example, if the current user's home directory is , then the command is equivalent to , , or . This convention derives from the ADM-3A terminal in common use during the 1970s, which happened to have the tilde symbol and the word "Home" (for moving the cursor to the upper left) on the same key. When prepended to a particular username, the tilde indicates that user's home directory (e.g., for the home directory of user , such as )..

Used in URLs on the World Wide Web, it often denotes a personal website on a -based server. For example, 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 in the user's home directory, such as or ..

In URLs, the characters (or ) may substitute for tilde if an input device lacks a tilde key.. Thus, and will behave in the same manner.


Computer languages
The tilde is used in the programming language as part of the pattern match operators for regular expressions:
  • ''variable'' ~ /''regex''/ returns true if the variable is matched.
  • ''variable'' !~ /''regex''/ returns false if the variable is matched.

A variant of this, with the plain tilde replaced with =~, was adopted in , and this semi-standardization has led to the use of these operators in other programming languages, such as Ruby or the variant of the database .

In APL and , tilde represents the monadic logical function NOT.

In the C, C++ and C# programming languages, the tilde character is used as operator, following the notation in logic (an ! causes a logical NOT, instead). In C++ and C#, the tilde is also used as the first character in a class's method name (where the rest of the name must be the same name as the class) to indicate a destructor – a special method which is called at the end of the .

In ASP.NET application tilde ('~') is used as a shortcut to the root of the application's virtual directory.

In the CSS stylesheet language, the tilde is used for the indirect adjacent combinator as part of a selector.

In the D programming language, the tilde is used as an array operator, as well as to indicate an object destructor and bitwise not operator. Tilde operator can be overloaded for user types, and binary tilde operator is mostly used to merging two objects, or adding some objects to set of objects. It was introduced because plus operator can have different meaning in many situations. For example, what to do with "120" + "14" ? Is this a string "134" (addition of two numbers), or "12014" (concatenation of strings) or something else? D disallows + operator for arrays (and strings), and provides separate operator for concatenation (similarly programming language solved this problem by using dot operator for concatenation, and + for number addition, which will also work on strings containing numbers).

In Eiffel, the tilde is used for object comparison. If a and b denote objects, the boolean expression a ~ b has value true if and only if these objects are equal, as defined by the applicable version of the library routine is_equal, which by default denotes field-by-field object equality but can be redefined in any class to support a specific notion of equality. If a and b are references, the object equality expression a ~ b is to be contrasted with a = b which denotes reference equality. Unlike the call a. is_equal ( b), the expression a ~ b is even in the presence of covariance.

In the Apache Groovy programming language the tilde character is used as an operator mapped to the bitwiseNegate() method. Given a String the method will produce a java.util.regex.Pattern. Given an integer it will negate the integer bitwise like in different C variants. =~ and ==~ can in Groovy be used to match a regular expression...

In Haskell, the tilde is used in type constraints to indicate type equality.. Also, in pattern-matching, the tilde is used to indicate a lazy pattern match.

In the programming language, the tilde is used to indicate a quotation mark inside a quoted string.

In "text mode" of the typesetting language a tilde diacritic can be obtained using, e.g., \~{n}, yielding "ñ". A stand-alone tilde can be obtained by using \textasciitilde or \string~. In "math mode" a tilde diacritic can be written as, e.g., \tilde{x}. For a wider tilde \widetilde can be used. The \sim command produce a tilde-like binary relation symbol that is often used in mathematical expressions, and the double-tilde ≈ is obtained with \approx. The url package also supports entering tildes directly, e.g., <nowiki></nowiki>. In both text and math mode, a tilde on its own (~) renders a white space with no line breaking.

In syntax, four tildes are used as a shortcut for a user's signature.

In , the tilde is used as the prefix for format specifiers in format strings. In Max/MSP, a tilde is used to denote objects that process at the computer's sampling rate, i.e. mainly those that deal with sound.

In , the tilde is used as the prefix for negative numbers and as the unary negation operator.

In , the tilde is used to specify the label for a labeled parameter.

In Microsoft's SQL Server language, the tilde is a unary Bitwise NOT operator.

In , the tilde is used as a unary bitwise complement (or bitwise negation) operation (~number). Because JavaScript internally uses floats and the bitwise complement only works on integers, numbers are stripped of their decimal part before applying the operation. This has also given rise to using two tildes ~~number as a short syntax for a cast to integer (numbers are stripped of their decimal part and changed into their complement, and then back. The net result is thus only the removal of the decimal part). For positive numbers, this is equivalent to the mathematical floor function.

In , the twiddle is used as a "message send" symbol. For example, Employee.name~lower() would cause the lower() method to act on the object Employee's name attribute, returning the result of the operation. ~~ returns the object that received the method rather than the result produced. Thus it can be used when the result need not be returned or when cascading methods are to be used. team~~insert("Jane")~~insert("Joe")~~insert("Steve") would send multiple concurrent insert messages, thus invoking the insert method three consecutive times on the team object.


Backup filenames
The dominant convention for naming backup copies of files is appending a tilde to the original file name. It originated with the text editor Emacs Manual and was adopted by many other editors and some command-line tools.

Emacs also introduced an elaborate numbered backup scheme, with files named , and so on. It didn't catch on, as the rise of software eliminates the need for this usage.


Microsoft filenames
The tilde was part of 's filename mangling scheme when it extended the FAT file system standard to support long filenames for Microsoft Windows. 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 characters from a restricted character set (e.g. no spaces), followed by a period, followed by three more characters. In order to permit these legacy programs to access files in the FAT 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, "" might become "".

The tilde symbol is also often used to prefix hidden temporary files that are created when a document is opened in Windows. For example, when a document "Document1.doc" is opened in Word, a file called "~$cument1.doc" is 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.


Other uses
Computer programmers use the tilde in various ways and sometimes call the symbol (as opposed to the diacritic) a squiggle, squiggly, or twiddle. According to the , other synonyms sometimes used in programming include not, approx, wiggle, enyay (after eñe) and (humorously) sqiggle . It is used in many languages as a binary inversion operator, swapping a number's binary 1's and 0's for example ~10 (binary ~1010) is equal to 5 (binary 0101).

In Perl 6, "http://www.example.com/~johndoe/" is used instead of "=~".


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". is thus represented as (~2x,1)(1,2x)(2x,~1)*.


Keyboards
Where a tilde is on the keyboard depends on the computer's language settings according to the following chart. On many keyboards it is primarily available through a that makes it possible to produce a variety of precomposed characters with the diacritic. In that case, a single tilde can typically be inserted with the dead key followed by the space bar, or alternatively by striking the dead key twice in a row.

To insert a tilde with the dead key, it is often necessary to simultaneously hold down the key. On the keyboard layouts that include an Alt Gr key, it typically takes the place of the right-hand . With a either of the Alt/ keys function similarly.

In the US and European systems, the for a single tilde is 126.
