The exclamation mark or exclamation point is a punctuation mark usually used after an interjection or exclamation to indicate strong feelings or high volume (shouting), and often marks the end of a sentence. Example: “Watch out!” The character is encoded in Unicode as U+0021 ! exclamation mark (HTML:
One theory of its origin is that it was a Latin exclamation of joy (io), written with the I above the o.
The exclamation mark was first introduced into English printing in the 15th century to show emphasis, and was called the "sign of admiration or exclamation" or the "note of admiration" until the mid-17th century; admiration referred to its Latin sense of wonderment.
The exclamation mark did not have its own dedicated key on standard manual typewriters before the 1970s. Instead, one typed a period, backspaced, and typed an apostrophe. In the 1950s, secretarial dictation and typesetting manuals in America referred to the mark as "bang," perhaps from comic books where the ! appeared in dialogue balloons to represent a gun being fired, although the nickname probably emerged from letterpress printing. This bang usage is behind the titles of the interrobang, an uncommon typographic character, and a shebang line, a feature of Unix computer systems.
Slang and other names for the exclamation mark 
This punctuation mark is called, in the printing world, "a screamer, a gasper, a startler, or ... a dog's cock".
In hacker culture, the exclamation mark is called "bang", "shriek", or, in the British slang known as Commonwealth Hackish, "pling". For example, the password communicated in the spoken phrase "Your password is em-zero-pee-aitch-pling-en-three" is m0ph!n3.
Other slang names are dembanger and shout pole.

The exclamation mark is common to languages using the Latin alphabet, although usage varies slightly between languages. The exclamation point is also used in languages with other scripts, such as Greek, Russian, Arabic, Hebrew, Chinese, Korean and Japanese but it has never been found in Hindi.
A sentence ending in an exclamation mark may be an exclamation (such as "Wow!", "Boo!"), or an imperative ("Stop!"), or may indicate astonishment: "They were the footprints of a gigantic duck!" Exclamation marks are occasionally placed mid-sentence with a function similar to a comma, for dramatic effect, although this usage is obsolescent: "On the walk, oh! there was a frightful noise."
Informally, exclamation marks may be repeated for additional emphasis ("That's great!!!"), but this practice is generally considered unacceptable in formal prose.
The exclamation mark is sometimes used in conjunction with the question mark. This can be in protest or astonishment ("Out of all places, the squatter-camp?!"); a few writers replace this with a single, nonstandard punctuation mark, the interrobang, which is the combination of a question mark and an exclamation point. Again, this is informal.
Overly frequent use of the exclamation mark is generally considered poor writing, for it distracts the reader and devalues the mark's significance.
- Cut out all those exclamation points. An exclamation point is like laughing at your own jokes.
- —F. Scott Fitzgerald
For information on the use of spaces after an exclamation mark, see the discussion of spacing after a full stop.
Several studies have shown that women use exclamation marks more than men do, and one study suggests that, in addition to other usage, exclamation points may also function as markers of friendly interaction, for example, by making "Hi!" or "Good luck!" seem friendlier than simply "Hi." or "Good luck." (with periods).
In French, next to marking exclamations or indicating astonishment, the exclamation mark is also commonly used to mark orders or requests: Viens ici ! (English: "Come here!"). A space (« espace fine ») is used between the last word and the exclamation mark.
- In the salutation line of a letter, for which English uses a comma: Lieber Hans! (English: "Dear Hans,") In this case, the first word of the following sentence begins with a capital letter. However, usage of a comma, as in English, is both also acceptable and far more common.
- On signs, not just those warning of danger as discussed below, the exclamation mark is used to emphasize the sign's content: Betreten verboten! (English: "No trespassing")
- At the end of an imperative sentence: Ruf mich morgen an! (English: "Call me tomorrow.")
- ¿Estás loco? ¡Casi la mataste! (English: "Are you crazy? You almost killed her!")
For informal written online communications, however, usage of inverted question and exclamation marks has become less common.
In Turkish, an exclamation mark is used after a sentence or phrase for emphasis, and is common following both commands and the addressees of such commands. For example, in Ordular! İlk hedefiniz Akdenizdir, ileri! ("Armies! Your first target is the Mediterranean") order by Atatürk, ordular (the armies) constitute the addressee. It is further used in parentheses "(!)" after a sentence or phrase to indicate irony or sarcasm: Çok iyi bir iş yaptın (!) ("You've done a very good job – Not!").
In Khoisan languages, and the International Phonetic Alphabet, the exclamation mark is used as a letter to indicate the postalveolar click sound (represented as q in Zulu orthography). In Unicode, this letter is properly coded as U+01C3 ǃ latin letter retroflex click and distinguished from the common punctuation symbol U+0021 ! exclamation mark to allow software to deal properly with word breaks.
The exclamation point has sometimes been used as a phonetic symbol to indicate that a consonant is ejective. More commonly this is represented by an apostrophe, or a superscript glottal stop symbol (U+02C0 ˀ modifier letter glottal stop).
There is a non–standard punctuation mark intended to combine the functions of a question mark and an exclamation mark in English called interrobang, which resembles those marks superimposed over one another ("‽") but it is seldom seen outside Wikipedia articles or Unicode documentation - the sequence of "?!" or "!?" is used almost exclusively.
Proper names 
Although exclamation marks are, as a standard, part of a complete sentence and not the spelling of individual words, they appear in many proper names, especially in commercial advertising. Prominent examples include the Web service Yahoo!, the game show Jeopardy! and the '60s musical TV show Shindig!. The titles of the musicals Oklahoma!, Oliver! and Oh! Calcutta! and the movies Airplane! and Moulin Rouge! also contain exclamation points. Writer Elliot S! Maggin and cartoonist Scott Shaw! include exclamation marks in their names.
Place names 
The English town of Westward Ho!, named after the novel by Charles Kingsley, is the only place name in the United Kingdom that officially contains an exclamation point. There is a town in Quebec called Saint-Louis-du-Ha! Ha!, which is spelled with two exclamation marks. The city of Hamilton, Ohio, changed its name to Hamilton! in 1986. The city of Ostrava, Czech Republic, changed its logotype to Ostrava!!! in 2008; however, the official name was still not changed yet.
Exclamation points are used to emphasize a precautionary statement.
On warning signs, an exclamation mark is often used to draw attention to a warning of danger, hazards, and the unexpected. These signs are common in hazardous environments or on potentially dangerous equipment. A common type of this warning is a yellow triangle with a black exclamation point, but a white triangle with a red border is common on European road warning signs.
In writing and often subtitles, especially in British English, a (!) symbol (an exclamation point within parentheses) implies that a character has made an obviously sarcastic comment e.g.: "Ooh, a sarcasm detector. That's a really useful invention(!)"

- U+07F9 ߹ nko exclamation mark
- U+109F ႟ myanmar symbol shan exclamation
- U+1944 ᥄ limbu exclamation mark
Use in various fields 
In mathematics, the symbol represents the factorial operation. The expression n! means "the product of the integers from 1 to n". For example, 4! (read four factorial) is 4 × 3 × 2 × 1 = 24. (0! is defined as 1, which is a neutral element in multiplication, not multiplied by anything.) It also can represent uniqueness.
In computing, the exclamation mark (sometimes called a "bang") corresponds to ASCII character 33 (21 in hexadecimal). It is therefore found in Unicode at U+0021 ! exclamation mark. The inverted exclamation mark is found in ISO-8859-1, 9 and 15 at position 161 (A1HEX) and in Unicode at U+00A1 ¡ inverted exclamation mark.
The name given to "!" by programmers varies according to their background. In the UK the term pling was popular in the earlier days of computing, whilst in the USA the term shriek was used. It is claimed that these word usages were invented in the US and shriek is from Stanford or MIT; however, shriek for the ! sign is found in the Oxford English Dictionary dating from the 1860s.
Several computer languages use "!" for various meanings, most importantly for logical negation; e.g. A != B means "A is not equal to B", and !A means "the logical negation of A" (also called "not A"). In the UK, BBC BASIC used pling as an indirection operator, equivalent to PEEK and POKE of four bytes at once.
Plings are also used in Acorn RISC OS to denote an application directory: a folder that when double clicked executes a program file inside called !Run. Other files in the appfolder generally contain resources the application needs to run. The appfolder can be viewed as a normal folder by double-clicking with the shift key held down. In addition, other special resource files such as !Boot (executed the first time the application containing it comes into view of the filer), !Sprites (an icon file containing icon definitions loaded if !Boot cannot be found) and !Help (a text, HTML or other executable file listed in the filer menu for the application) also start with a pling.
In the Geek Code version 3, "!" is used before a letter to denote that the geek refuses to participate in the topic at hand. In some cases, it has an alternate meaning, such as G! denoting a geek of no qualifications, !d denoting not wearing any clothes, P! denoting not being allowed to use Perl, and so on. They all share some negative connotations however.
When computer programs display messages that alert the user, an exclamation mark may be shown alongside it to indicate that the message is important and should be read. This often happens when an error is made, or to obtain user consent for hazardous operations such as deleting data.
In UNIX scripting (typically for UNIX shell or Perl), "!" is usually used after a "#" in the first line of a script, the interpreter directive, to tell the OS what program to use to run the script. The "#!" is usually called a "hash-bang" or shebang.
In the Haskell programming language, "!" is used to express strictness.
Video games 
In the Metal Gear series of stealth games, a red exclamation point (!) appears above an enemy's head with a short, loud noise if they see the player. When this happens, the enemy will try to attack the player.
In the Pokémon series, rival trainers have an exclamation point appear above the head of other trainers when they spot the main character's trainer. In certain Versions of the game an exclamation point also appears on the main character's head when they hook a fish on one of the game's three rods (Old Rod, Good Rod and Super Rod).
In the Paper Mario series, enemies have an exclamation point appear over their heads if they notice Mario, Luigi, Peach, or Bowser.
In the Warcraft series, NPCs having available quests for players are represented with an yellow exclamation point floating over their heads. If the quest is repeatable it is represented with a blue exclamation point.
In the Counter-Strike games, a green exclamation point appears above a player's head if the player uses a radio command.
In "Minecraft" the splash screen includes a quote followed by an exclamation point.
In Yukon World when ever anybody sees the main character Yukon the screen will fill with exclamation points because the game revolves around Yukon.
Internet culture

In recent Internet culture, especially where leet is used, multiple exclamation marks may be affixed with the numeral "1" as in !!!!!!111. The notation originates from a common error: when typing multiple exclamation points quickly, the typist may fail to hold the ⇧ Shift1 combination which produces the exclamation mark on many keyboard layouts. This error, first used intentionally as a joke in the leet linguistic community, is now an accepted form of exclamation in leet and derivative dialects such as Lolspeak. Some utterances include further substitutions, for example "!!!111oneeleven".
In fandom and fanfiction, ! is used to signify a defining quality in a character, usually signifying an alternate interpretation of a character from a canonical work. Examples of this would be "Romantic!Draco" or "Vampire!Harry" from Harry Potter fandom. It is also used to clarify the current persona of a character with multiple identities or appearances, such as to distinguish "Armor!Al" from "Human!Al" in a work based on Fullmetal Alchemist. The origin of this usage is unknown, although it is hypothesized to have originated with certain Teenage Mutant Ninja Turtles action figures, for example, "Football Player! Leonardo", "Rockstar! Raphael", and "Breakdancer! Michelangelo".
Some comic books, especially superhero comics of the mid-20th century, routinely use the exclamation point instead of the period, which means the character has just realized something; unlike when the question mark appears instead, which means the character is confused, surprised or he does not know what is happening. This tends to lead to exaggerated speech, in line with the other hyperboles common in comic books. A portion of the motivation, however, was simply that a period might disappear in the printing process used at the time, whereas an exclamation point would likely remain recognizable even if there was a printing glitch. For a short period Stan Lee, as Editor-in-Chief of Marvel Comics, attempted to curb their overuse by a short-lived ban on exclamation points altogether, which led to an inadvertent lack of ending punctuation on many sentences.
Comic book writer Elliot S! Maggin once accidentally signed his name with an exclamation due to the habit of using them when writing comic scripts; it became his professional name from then on. Similarly, comic artist Scott Shaw! has used the exclamation point after his name throughout his career.
In comic books and comics in general, a large exclamation point is often used near or over a character's head to indicate surprise. A question mark can similarly be used to indicate confusion. This practice also appears in some video games.
In chess notation "!" denotes a good move, "!!" denotes an excellent move, "?!" denotes a dubious move, and "!?" denotes an interesting, risky move. In some chess variants such as large-board Shogi variants, "!" is used to record pieces capturing by stationary feeding or burning.
In Scrabble, an exclamation mark written after a word is used to indicate its presence in the Official Tournament and Club Word List but its absence from the Official Scrabble Players Dictionary, usually because the word has been judged offensive.
Popular music 
In 2008, the pop punk band Panic! At the Disco dropped the exclamation point in its name; this became the "most-discussed topic on [fan] message boards around the world". In 2009, the exclamation mark was re-inserted following the band's split.
The band Bomb the Music Industry! utilizes an exclamation mark in its name, as well as several album and song titles and promotional material. Examples include their songs "(Shut) Up The Punx!!!" and the album Adults!!!: Smart!!! Shithammered!!! And Excited by Nothing!!!!!!!.
The exclamation mark was the subject of a bitter argument between Elaine Benes and her boyfriend, Jake Jarmel, in the Seinfeld episode, “The Sniffing Accountant”. Elaine got upset with Jake for not putting an exclamation mark at the end of a message about a friend having a baby. Jake took extreme exception to the trivial criticism and broke up with Elaine, putting an exclamation mark after his parting words: “I’M LEAVING!” Yukon made the song the goat and the tree which evolves an Exclamation mark because it refers to the mark in the song at the end when his voice hypes up.
