Шаблон:Short description Шаблон:About Шаблон:More citations needed Шаблон:EngvarB Шаблон:Use dmy dates Шаблон:Infobox punctuation mark A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings.Шаблон:Sfn They come in four main pairs of shapes, as given in the box to the right, which also gives their names, that vary between British and American English.Шаблон:Sfn "Brackets", without further qualification, are in British English the Шаблон:Char…Шаблон:Char marks and in American English the Шаблон:Char…Шаблон:Char marks.Шаблон:SfnШаблон:Sfn

Other minor bracket shapes exist, such as (for example) slash or diagonal brackets used by linguists to enclose phonemes.Шаблон:Sfn

Brackets are typically deployed in symmetric pairs, and an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context.

In casual writing and in technical fields such as computing or linguistic analysis of grammar, brackets nest, with segments of bracketed material containing embedded within them other further bracketed sub-segments.Шаблон:Sfn The number of opening brackets matches the number of closing brackets in such cases.Шаблон:Sfn

Various forms of brackets are used in mathematics, with specific mathematical meanings, often for denoting specific mathematical functions and subformulas.

History

Angle brackets or chevrons ⟨ ⟩ were the earliest type of bracket to appear in written English. Erasmus coined the term Шаблон:Lang to refer to the round brackets or parentheses (Шаблон:Nbsp) recalling the shape of the crescent moon (Шаблон:Lang-la).

Most typewriters only had the left and right parentheses. Square brackets appeared with some teleprinters.

Braces (curly brackets) first became part of a character set with the 8-bit code of the IBM 7030 Stretch.

In 1961, ASCII contained parentheses, square, and curly brackets, and also less-than and greater-than signs that could be used as angle brackets.

Typography

In English, typographers mostly prefer not to set brackets in italics, even when the enclosed text is italic. However, in other languages like German, if brackets enclose text in italics, they are usually also set in italics.

Parentheses or (round) brackets

Шаблон:Char and Шаблон:Char are parentheses Шаблон:IPAc-en (singular parenthesis Шаблон:IPAc-en) in American English, and either round brackets or simply brackets in British English.Шаблон:SfnШаблон:Sfn They are also known as "parens" Шаблон:IPAc-en, "circle brackets", or "smooth brackets".

In careful or formal writing, "parentheses" is also used in British English.Шаблон:Citation needed

Uses of ( )

Parentheses contain adjunctive material that serves to clarify (in the manner of a gloss) or is aside from the main point.

A comma before or after the material can also be used, though if the sentence contains commas for other purposes, visual confusion may result. A dash before and after the material is also sometimes used.

Parentheses may be used in formal writing to add supplementary information, such as "Senator John McCain (R - Arizona) spoke at length". They can also indicate shorthand for "either singular or plural" for nouns, e.g. "the claim(s)". It can also be used for gender-neutral language, especially in languages with grammatical gender, e.g. "(s)he agreed with his/her physician" (the slash in the second instance, as one alternative is Шаблон:Em the other, not Шаблон:Em to it).

Parenthetical phrases have been used extensively in informal writing and stream of consciousness literature. Examples include the southern American author William Faulkner (see Absalom, Absalom! and the Quentin section of The Sound and the Fury) as well as poet E. E. Cummings.

Parentheses have historically been used where the dash is currently used in alternatives, such as "parenthesis)(parentheses". Examples of this usage can be seen in editions of Fowler's Dictionary of Modern English Usage.

Parentheses may be nested (generally with one set (such as this) inside another set). This is not commonly used in formal writing (though sometimes other brackets [especially square brackets] will be used for one or more inner set of parentheses [in other words, secondary {or even tertiary} phrases can be found within the main parenthetical sentence]).

Language

A parenthesis in rhetoric and linguistics refers to the entire bracketed text, not just to the enclosing marks used (so all the text in this set of round brackets may be described as "a parenthesis"). Taking as an example the sentence "Mrs. Pennyfarthing (What? Yes, that was her name!) was my landlady.", the explanatory phrase between the parentheses is itself called a parenthesis. Again, the parenthesis implies that the meaning and flow of the bracketed phrase is supplemental to the rest of the text and the whole would be unchanged were the parenthesized sentences removed. The term refers to the syntax rather than the enclosure method: the same clause in the form "Mrs. PennyfarthingШаблон:SndWhat? Yes, that was her name!Шаблон:Sndwas my landlady" is also a parenthesis. (In non-specialist usage, the term "parenthetical phrase" is more widely understood.)

In phonetics, parentheses are used for indistinguishable or unidentified utterances. They are also seen for silent articulation (mouthing), where the expected phonetic transcription is derived from lip-reading, and with periods to indicate silent pauses, for example Шаблон:IPA or Шаблон:IPA.

Enumerations

An unpaired right parenthesis is often used as part of a label in an ordered list, such as this one: Шаблон:Blockquote

Accounting

Traditionally in accounting, contra amounts are placed in parentheses. A debit balance account in a series of credit balances will have parenthesis and vice versa.

Parentheses in mathematics

Parentheses are used in mathematical notation to indicate grouping, often inducing a different order of operations. For example: in the usual order of algebraic operations, Шаблон:Math equals 14, since the multiplication is done before the addition. However, Шаблон:Math equals 20, because the parentheses override normal precedence, causing the addition to be done first. Some authors follow the convention in mathematical equations that, when parentheses have one level of nesting, the inner pair are parentheses and the outer pair are square brackets. Example:

<math>[4 \times (3 + 2)]^2 = 400.</math>

Parentheses in programming languages

Parentheses are included in the syntaxes of many programming languages. Typically needed to denote an argument; to tell the compiler what data type the Method/Function needs to look for first in order to initialise. In some cases, such as in LISP, parentheses are a fundamental construct of the language. They are also often used for scoping functions and operators and for arrays. In syntax diagrams they are used for grouping, such as in extended Backus–Naur form.

In Mathematica and the Wolfram language, parentheses are used to indicate groupingШаблон:Snd for example, with pure anonymous functions.

Taxonomy

If it is desired to include the subgenus when giving the scientific name of an animal species or subspecies, the subgenus's name is provided in parentheses between the genus name and the specific epithet. For instance, Polyphylla (Xerasiobia) alba is a way to cite the species Polyphylla alba while also mentioning that it is in the subgenus Xerasiobia. There is also a convention of citing a subgenus by enclosing it in parentheses after its genus, e.g., Polyphylla (Xerasiobia) is a way to refer to the subgenus Xerasiobia within the genus Polyphylla. Parentheses are similarly used to cite a subgenus with the name of a prokaryotic species, although the International Code of Nomenclature of Prokaryotes (ICNP) requires the use of the abbreviation "subgen." as well, e.g., Acetobacter (subgen. Gluconoacetobacter) liquefaciens.

Chemistry

Parentheses are used in chemistry to denote a repeated substructure within a molecule, e.g. HC(CH₃)₃ (isobutane) or, similarly, to indicate the stoichiometry of ionic compounds with such substructures: e.g. Ca(NO₃)₂ (calcium nitrate).

This is a notation that was pioneered by Berzelius, who wanted chemical formulae to more resemble algebraic notation, with brackets enclosing groups that could be multiplied (e.g. in 3(AlO₂ + 2SO₃) the 3 multiplies everything within the parentheses).Шаблон:SfnШаблон:Sfn

In chemical nomenclature, parentheses are used to distinguish structural features and multipliers for clarity, for example in the polymer poly(methyl methacrylate).

Square brackets

Шаблон:Infobox punctuation mark Шаблон:Wiktionary pipe Шаблон:Char and Шаблон:Char are square brackets in both British and American English, but are also more simply brackets in the latter.Шаблон:SfnШаблон:Sfn An older name for these brackets is "crotchets".

Uses of [ ]

Square brackets are often used to insert explanatory material or to mark where a [word or] passage was omitted from an original material by someone other than the original author, or to mark modifications in quotations. In transcribed interviews, sounds, responses and reactions that are not words but that can be described are set off in square brackets — "... [laughs] ...".

When quoted material is in any way altered, the alterations are enclosed in square brackets within the quotation to show that the quotation is not exactly as given, or to add an annotation. For example: The Plaintiff asserted his cause is just, stating, Шаблон:Blockquote In the original quoted sentence, the word "my" was capitalized: it has been modified in the quotation given and the change signalled with brackets. Similarly, where the quotation contained a grammatical error (is/are), the quoting author signalled that the error was in the original with "[sic]" (Latin for 'thus').

A bracketed ellipsis, [...], is often used to indicate omitted material: "I'd like to thank [several unimportant people] for their tolerance [...]" Bracketed comments inserted into a quote indicate where the original has been modified for clarity: "I appreciate it [the honor], but I must refuse", and "the future of psionics [see definition] is in doubt". Or one can quote the original statement "I hate to do laundry" with a (sometimes grammatical) modification inserted: He "hate[s] to do laundry".

Additionally, a small letter can be replaced by a capital one, when the beginning of the original printed text is being quoted in another piece of text or when the original text has been omitted for succinctness— for example, when referring to a verbose original: "To the extent that policymakers and elite opinion in general have made use of economic analysis at all, they have, as the saying goes, done so the way a drunkard uses a lamppost: for support, not illumination", can be quoted succinctly as: "[P]olicymakers [...] have made use of economic analysis [...] the way a drunkard uses a lamppost: for support, not illumination." When nested parentheses are needed, brackets are sometimes used as a substitute for the inner pair of parentheses within the outer pair. When deeper levels of nesting are needed, convention is to alternate between parentheses and brackets at each level.

Alternatively, empty square brackets can also indicate omitted material, usually single letter only. The original, "Reading is also a process and it also changes you." can be rewritten in a quote as: It has been suggested that reading can "also change[] you".

In translated works, brackets are used to signify the same word or phrase in the original language to avoid ambiguity. For example: He is trained in the way of the open hand [karate].

Style and usage guides originating in the news industry of the twentieth century, such as the AP Stylebook, recommend against the use of square brackets because "They cannot be transmitted over news wires." However, this guidance has little relevance outside of the technological constraints of the industry and era.

In linguistics, phonetic transcriptions are generally enclosed within square brackets, whereas phonemic transcriptions typically use paired slashes, according to International Phonetic Alphabet rules. Pipes (| |) are often used to indicate a morphophonemic rather than phonemic representation. Other conventions are double slashes (// //), double pipes (|| ||) and curly brackets ({ }).

In lexicography, square brackets usually surround the section of a dictionary entry which contains the etymology of the word the entry defines.

Proofreading

Brackets (called move-left symbols or move right symbols) are added to the sides of text in proofreading to indicate changes in indentation:

Move left	[To Fate I sue, of other means bereft, the only refuge for the wretched left.
Center	]Paradise Lost[
Move up	Файл:Quote to be Moved Up.svg

Square brackets are used to denote parts of the text that need to be checked when preparing drafts prior to finalizing a document.

Law

Square brackets are used in some countries in the citation of law reports to identify parallel citations to non-official reporters. For example: Шаблон:Blockquote In some other countries (such as England and Wales), square brackets are used to indicate that the year is part of the citation and parentheses are used to indicate the year the judgment was given. For example: Шаблон:Blockquote This case is in the 1954 volume of the Appeal Cases reports, although the decision may have been given in 1953 or earlier. Compare with: Шаблон:Blockquote This citation reports a decision from 1954, in volume 98 of the Solicitors Journal which may be published in 1955 or later.

They often denote points that have not yet been agreed to in legal drafts and the year in which a report was made for certain case law decisions.

Square brackets in mathematics

Шаблон:Main Brackets are used in mathematics in a variety of notations, including standard notations for commutators, the floor function, the Lie bracket, equivalence classes, the Iverson bracket, and matrices.

Square brackets may be used exclusively or in combination with parentheses to represent intervals as interval notation.Шаблон:Sfn For example, Шаблон:Math represents the set of real numbers from 0 to 5 inclusive. Both parentheses and brackets are used to denote a half-open interval; Шаблон:Closed-open would be the set of all real numbers between 5 and 12, including 5 but not 12. The numbers may come as close as they like to 12, including 11.999 and so forth, but 12.0 is not included. Шаблон:Cn-span The endpoint adjoining the square bracket is known as closed, whereas the endpoint adjoining the parenthesis is known as open.Шаблон:Sfn

In group theory and ring theory, brackets denote the commutator. In group theory, the commutator Шаблон:Math is commonly defined as Шаблон:Math. In ring theory, the commutator Шаблон:Math is defined as Шаблон:Math.

Chemistry

Square brackets can also be used in chemistry to represent the concentration of a chemical substance in solution and to denote charge a Lewis structure of an ion (particularly distributed charge in a complex ion), repeating chemical units (particularly in polymers) and transition state structures, among other uses.

Square brackets in programming languages

Brackets are used in many computer programming languages, primarily for array indexing. But they are also used to denote general tuples, sets and other structures, just as in mathematics. There may be several other uses as well, depending on the language at hand. In syntax diagrams they are used for optional portions, such as in extended Backus–Naur form.

Double brackets ⟦ ⟧

Double brackets (or white square brackets or Scott brackets), ⟦ ⟧, are used to indicate the semantic evaluation function in formal semantics for natural language and denotational semantics for programming languages. In the Wolfram Language, double brackets, either as iterated single brackets ([[) or ligatures (〚) are used for list indexing.

The brackets stand for a function that maps a linguistic expression to its "denotation" or semantic value. In mathematics, double brackets may also be used to denote intervals of integers or, less often, the floor function. In papyrology, following the Leiden Conventions, they are used to enclose text that has been deleted in antiquity.

Brackets with quills ⁅ ⁆

Known as "spike parentheses" (Шаблон:Lang-sv), Шаблон:Code and Шаблон:Code are used in Swedish bilingual dictionaries to enclose supplemental constructions.

Curly brackets

Шаблон:Infobox punctuation mark Шаблон:Char and Шаблон:Char are braces in both American and British English, and also curly brackets in the latter.Шаблон:SfnШаблон:Sfn

Uses of { }

Файл:Curly Bracket Notation.png

An example of curly brackets used to group sentences together

Curly brackets are used by text editors to mark editorial insertions or interpolations.

Braces used to be used to connect multiple lines of poetry, such as triplets in a poem of rhyming couplets, although this usage had gone out of fashion by the 19th century.Шаблон:SfnШаблон:Sfn

Another older use in prose was to eliminate duplication in lists and tables.Шаблон:Sfn Two examples here from Charles Hutton's 19th century table table of weights and measures in his A Course of Mathematics:

In this kingdomШаблон:Sfn

The standard of …	⎧	Length is a Yard.
	⎪	Surface is a Square Yard, the Шаблон:Frac of an Acre.
	⎨	⎰ Solidity is a Cubic Yard.
	⎪	⎱ Capacity is a Gallon.
	⎩	Weight is a Pound.

Imperial measure of CAPACITY for coals, culm, lime, fish, potatoes, fruit,– and other goods commonly sold by heaped measure:Шаблон:Sfn

2 Gallons	= 1 Peck	= 764	⎱	Cubic Inches, nearly
8 Gallons	= 1 Bushel	= 2813Шаблон:Frac	⎰
3 Bushels	= 1 Sack	= 4Шаблон:Frac	⎱	Cubic Feet, nearly
12 Sacks	= 1 Chald.	= 58Шаблон:Frac	⎰

As an extension to the International Phonetic Alphabet (IPA), braces are used for prosodic notation.

Music

In music, they are known as "accolades" or "braces", and connect two or more lines (staves) of music that are played simultaneously.

Chemistry

The use of braces in chemistry is an old notation that has long since been superseded by subscripted numbers.Шаблон:Sfn The chemical formula for water, H₂O, was represented as <math>\left . \stackrel{H}{H} \right \} O</math>.Шаблон:Sfn

Curly brackets in programming languages

Шаблон:See also In many programming languages, curly brackets enclose groups of statements and create a local scope. Such languages (C, C#, C++ and many others) are therefore called curly bracket languages. They are also used to define structures and enumerated type in these languages.

In various Unix shells, they enclose a group of strings that are used in a process known as brace expansion, where each successive string in the group is interpolated at that point in the command line to generate the command-line's final form.Шаблон:Sfn The mechanism originated in the C shell and the string generation mechanism is a simple interpolation that can occur anywhere in a command line and takes no account of existing filenames.Шаблон:Sfn

In syntax diagrams they are used for repetition, such as in extended Backus–Naur form.

In the Z formal specification language, braces define a set.

Curly brackets in mathematics

Шаблон:Main In mathematics they delimit sets, in what is called set notation.Шаблон:Sfn Braces enclose either a literal list of set elements, or a rule that defines the set elements.Шаблон:Sfn For example:

• Шаблон:Math defines a set Шаблон:Mvar containing Шаблон:Mvar and Шаблон:Mvar.Шаблон:Sfn
• Шаблон:Math defines a set Шаблон:Mvar containing elements (implied to be numbers) Шаблон:Math, Шаблон:Math, and so on where every Шаблон:Math satisfies the rule that it is greater than zero.Шаблон:Sfn

They are often also used to denote the Poisson bracket between two quantities.

In ring theory, braces denote the anticommutator where Шаблон:Math is defined as Шаблон:Math.

Angle brackets

Шаблон:Char and Шаблон:Char are angle brackets in both American and British English.Шаблон:SfnШаблон:Sfn In computer slang, they are known as "brokets".

Strictly speaking they are distinct from V-shaped chevrons, as they have (where the typography permits it) a broader span than chevrons,Шаблон:Sfn although when printed often no visual distinction is made.Шаблон:Sfn

The ASCII less-than and greater-than characters Шаблон:Tt are often used for angle brackets. In most cases only those characters are accepted by computer programs, and the Unicode angle brackets are not recognized (for instance, in HTML tags). The characters for "single" guillemets Шаблон:Tt are also often used, and sometimes normal guillemets Шаблон:Tt when nested angle brackets are needed.

The angle brackets or chevrons at U+27E8 and U+27E9 are for mathematical use and Western languages, whereas U+3008 and U+3009 are for East Asian languages. The chevrons at U+2329 and U+232A are deprecated in favour of the U+3008 and U+3009 East Asian angle brackets. Unicode discourages their use for mathematics and in Western texts, because they are canonically equivalent to the CJK code points U+300x and thus likely to render as double-width symbols. The less-than and greater-than symbols are often used as replacements for chevrons.

Shape

Angle brackets are larger than less-than and greater-than signs, which in turn are larger than guillemets.

Файл:Angle brackets and less+greater signs and half guillemets in different fonts.svg

Angle brackets, less-than/greater-than signs and single guillemets in fonts Cambria, DejaVu Serif, Andron Mega Corpus, Andika and Everson Mono

Uses of ⟨ ⟩

Angle brackets are infrequently used to denote words that are thought instead of spoken, such as:

Шаблон:Angbr

In textual criticism, and hence in many editions of pre-modern works, chevrons denote sections of the text which are illegible or otherwise lost; the editor will often insert their own reconstruction where possible within them.

In comic books, chevrons are often used to mark dialogue that has been translated notionally from another language; in other words, if a character is speaking another language, instead of writing in the other language and providing a translation, one writes the translated text within chevrons. Since no foreign language is actually written, this is only notionally translated.Шаблон:Citation needed

In linguistics, angle brackets identify graphemes (Шаблон:Abbr, letters of an alphabet) or orthography, as in "The English word Шаблон:IPA is spelled Шаблон:Angbr." Шаблон:Crossref

In epigraphy, they may be used for mechanical transliterations of a text into the Latin script.

In East Asian punctuation, angle brackets are used as quotation marks. Chevron-like symbols are part of standard Chinese, Japanese andШаблон:Snd less frequentlyШаблон:Snd Korean punctuation, where they generally enclose the titles of books, as: ︿... ﹀ or ︽...︾ for traditional vertical printing — written in vertical lines — and as 〈 ... 〉 or 《 ... 》 for horizontal printing — in horizontal.

Angle brackets in mathematics

Шаблон:Main Angle brackets (or 'chevrons') are used in group theory to write group presentations, and to denote the subgroup generated by a collection of elements. In set theory, chevrons or parentheses are used to denote ordered pairs and other tuples, whereas curly brackets are used for unordered sets.

Physics and mechanics

In physical sciences and statistical mechanics, angle brackets are used to denote an average (expected value) over time or over another continuous parameter. For example:

<math>\left\langle V(t)^2 \right\rangle = \lim_{T\to\infty} \frac{1}{T}\int_{-\frac{T}{2}}^{\frac{T}{2}} V(t)^2\,{\rm{d}}t. </math>

In mathematical physics, especially quantum mechanics, it is common to write the inner product between elements as Шаблон:Math, as a short version of Шаблон:Math, or Шаблон:Math, where Шаблон:Math is an operator. This is known as Dirac notation or bra–ket notation, to note vectors from the dual spaces of the Bra Шаблон:Angbr. But there are other notations used.

In continuum mechanics, chevrons may be used as Macaulay brackets.

Angle brackets in programming languages

In C++ chevrons (actually less-than and greater-than) are used to surround arguments to templates. They are also used to surround the names of header files; this usage was inherited from and is also found in C.

In the Z formal specification language, chevrons define a sequence.

In HTML, chevrons (actually 'greater than' and 'less than' symbols) are used to bracket meta text. For example Шаблон:Tag denotes that the following text should be displayed as bold. Pairs of meta text tags are required – much as brackets themselves are usually in pairs. The end of the bold text segment would be indicated by Шаблон:Tag. This use is sometimes extended as an informal mechanism for communicating mood or tone in digital formats such as messaging, for example adding "<sighs>" at the end of a sentence.

Other brackets

Lenticular brackets【】

Шаблон:Wiktionary Some East Asian languages use lenticular brackets Шаблон:Char Шаблон:Char, a combination of square brackets and round brackets called Шаблон:Linktext (fāngtóu kuòhào) in Chinese and Шаблон:Lang (sumitsuki kakko) in Japanese. They are used in titles and headings in both Chinese and Japanese. On the Internet, they are used to emphasize a text. In Japanese, they are most frequently seen in dictionaries for quoting Chinese characters and Sino-Japanese loanwords.

Floor ⌊ ⌋ and ceiling ⌈ ⌉ corner brackets

Шаблон:Infobox punctuation mark Шаблон:Wiktionary The floor corner brackets Шаблон:Char and Шаблон:Char, the ceiling corner brackets Шаблон:Char and Шаблон:Char (U+2308, U+2309) are used to denote the integer floor and ceiling functions.

Quine corners ⌜⌝ and half brackets ⸤ ⸥ or ⸢ ⸣

The Quine corners Шаблон:Char and Шаблон:Char have at least two uses in mathematical logic: either as quasi-quotation, a generalization of quotation marks, or to denote the Gödel number of the enclosed expression.

Half brackets are used in English to mark added text, such as in translations: "Bill saw ⸤her⸥".

In editions of papyrological texts, half brackets, ⸤ and ⸥ or ⸢ and ⸣, enclose text which is lacking in the papyrus due to damage, but can be restored by virtue of another source, such as an ancient quotation of the text transmitted by the papyrus. For example, Callimachus Iambus 1.2 reads: ἐκ τῶν ὅκου βοῦν κολλύ⸤βου π⸥ιπρήσκουσιν. A hole in the papyrus has obliterated βου π, but these letters are supplied by an ancient commentary on the poem. Second intermittent sources can be between ⸢ and ⸣. Quine corners are sometimes used instead of half brackets.
