An open bracket has an open end to its right, while a closed bracket has an open end to its eft. Brackets are the two keys located next to the P key on a US QWERTY keyboard.
The notation may be a little confusing, but just remember that square brackets mean the end point is included, and round parentheses mean it's excluded. If both end points are included the interval is said to be closed, if they are both excluded it's said to be open.
- Soft, or open, brackets: () are used in algebra to separate sets or to denote a value that is not allowed as part of the domain or range of a function. They are also used to signify ordered points.
() are parentheses. They are used to supply additional information and comments to a sentence. [] are square brackets, which are used to supply context to a sentence with omitted information. {} are curly brackets, which don't have a literary use but are used in programming commonly.
If you are adding extra information to a quoted material, use brackets. But if there are no quotation marks, use a pair of parentheses.
Words can be added or changed to a quote by using brackets. Changes can be used to correct tense or to add necessary information. Brackets can also be used to make the pronouns in a quote consistent. However, brackets should not be used to change the meaning of the quote.
An em dash is a punctuation mark that can be used to replace commas, parentheses, colons, and semicolons. In general, the em dash is seen as being more interruptive or striking than other punctuation, so it is often used stylistically to draw a reader's attention to a particular bit of information.
There are four primary types of brackets. In British usage they are known as round brackets (or simply "brackets"), square brackets, curly brackets, and angle brackets; in American usage they are respectively known as parentheses, brackets, braces, and chevrons.
Square brackets []
Square brackets, often just called brackets in American English, are typically only used with quotations in formal writing.
Curly brackets {}
Curly brackets, also known as braces, are rarely used punctuation marks that are used to group a set.
Creating the "[" and "]" symbols on a U.S. keyboard
Pressing the open or close bracket key creates an open or bracket. Pressing and holding Shift while pressing [ creates a curly bracket. Doing the Alt code Alt +91 creates an open bracket and Alt +93 creates a close bracket.
A parenthesis is the same as an 'open circle' and a bracket is the same as a 'closed circle'.
Parentheses, ( or ), are used to signify that an endpoint value is not included, called exclusive. Brackets, [ or ], are used to indicate that an endpoint value is included, called inclusive.
Generally, three kinds of brackets are used in mathematics, Parentheses or Round Brackets, ( ) Curly or Brace Brackets { } Square or Box Brackets [ ]
[], are used for "commands", whereas parenthesis, (), are used for functions.
There are two types of dash. The en dash is approximately the length of the letter N, and the em dash the length of the letter M. The shorter en dash (–) is used to mark ranges and with the meaning “to” in phrases like “Dover–Calais crossing.”
The dash (—), also called the em dash, is the long horizontal bar, much longer than a hyphen. Few keyboards have a dash, but a word processor can usually produce one in one way or another.
Typically, a hyphen is used to connect the words in a compound adjective (see below). However, when the compound adjective contains an entity that is made up of multiple words, it's correct to use an en-dash.
What Is a Long Quotation? If your quotation extends to more than four lines as you're typing your essay, it is a long quotation. There are 4 rules that apply to long quotations that are different from regular quotations: The line before your long quotation, when you're introducing the quote, usually ends with a colon.
If an ellipsis is placed at the beginning or in the middle of a sentence, it means something has been removed, or it represents a silence or pause, as if the speaker trailed off. If an ellipsis comes at the end of a sentence, it suggests that there's more to the story.
The question mark ? (also known as interrogation point, query, or eroteme in journalism) is a punctuation mark that indicates an interrogative clause or phrase in many languages.
