What Is The Long Hyphen Called? | Em Dash Name

If you stare at a page and see a long horizontal line sitting between words, you may wonder what that long hyphen is called and why it looks different from the small hyphen on your keyboard. Writers, editors, and students run into this mark all the time in books, essays, and online posts.

The short answer is that the “long hyphen” usually has a proper name: the em dash. In some contexts people also mean the en dash, a slightly shorter mark. Once you know the names and jobs of each dash, punctuation choices become much easier.

What Is The Long Hyphen Called? Main Name In Writing

Strictly speaking, there is no mark in professional typography whose official name is “long hyphen.” Instead, style guides describe three main horizontal marks: the hyphen, the en dash, and the em dash. Together they cover most uses that people loosely group under the word hyphen.

The long hyphen people point to in running text is almost always the em dash (—). This mark is longer than both the hyphen (-) and the en dash (–), and many writers use it to set off extra information or show a sharp break in thought.

Character	Correct Name	Typical Length
–	Hyphen or Hyphen-Minus	Shortest
–	En Dash	Medium (about an “N” wide)
—	Em Dash	Longest (about an “M” wide)
‒	Figure Dash	Digit width
―	Horizontal Bar	Long dash for quoted text
−	Minus Sign	Math symbol close to an en dash
⸺	Two-Em Dash	Twice the em dash length

Typographic references such as the Unicode general punctuation chart give each of these marks its own code point and name, which confirms that “long hyphen” is only a casual label, not a technical term.

Hyphen, En Dash, And Em Dash Jobs

Knowing the answer to what is the long hyphen called is easier once you see how each mark behaves inside real sentences. The short hyphen connects; the en dash often stands for “to” or “through”; the em dash separates or adds emphasis.

Sizes matter less than role, yet the visual difference helps learners remember the pattern. As the marks grow longer, their jobs shift from tight connection toward looser separation, which is why many teachers describe the em dash as a strong pause rather than a simple join.

Hyphen: The Small Connector

The plain hyphen is the mark you see in everyday compound words such as “part-time,” “well-known,” or “mother-in-law.” It can join prefixes to words, split words at the end of a line, and handle most small linking jobs between terms.

On a standard keyboard the hyphen key produces a hyphen-minus, which doubles as a hyphen and a simple minus sign in basic text. For casual writing this is fine, but in professionally set text typographers often replace that generic mark with more precise characters.

Print dictionaries often signal possible line breaks with slightly longer hyphens between syllables. Those extra-long hyphens are still variants of the same basic mark and remind readers that hyphenation rules deal with sound chunks as well as spelling patterns.

En Dash: Range And Connection

The en dash sits between the hyphen and the em dash in length. Style manuals commonly use it to mark ranges such as “2019–2023,” “pages 10–18,” or a train line like “London–Paris route.” Some guides also use it to connect open compounds, as in “New York–based office.”

Many word processors include a built in shortcut for the en dash, and the Unicode name “En Dash” appears clearly in official code charts. In everyday speech people still may call it a dash or a small long hyphen, but in print its correct label matters.

Em Dash: The Usual Long Hyphen

The em dash is the mark that most people have in mind when they ask about the long hyphen’s name. In many fonts it is about the same width as a capital M. It stands out on the page and gives writers a flexible tool for sentence rhythm.

Writers often drop an em dash into a sentence to signal a pause stronger than a comma but less final than a full stop. It can replace a colon before a summary or explanation, or stand in for parentheses around an aside that the writer wants to bring forward.

Many style guides, including major dictionaries, describe the em dash in detail. For instance, the Merriam-Webster em dash guide shows how it can stand in for commas, colons, or parentheses while keeping prose smooth.

Typing The Long Hyphen On Different Devices

Another reason readers ask about the long hyphen’s name lies in the gap between how the mark looks and how easy it is to type. The hyphen sits on the keyboard, while the en dash and em dash hide behind key combinations or menu commands.

Windows And Linux

On Windows, one common method uses the numeric keypad. Holding Alt and typing 0151 produces an em dash, and Alt plus 0150 produces an en dash. Some software also converts two hyphens in a row into an em dash once you finish the word.

On many Linux setups, a compose key sequence can insert these marks. For example, pressing the compose key then the minus sign twice can insert an en dash, and three presses can insert an em dash, depending on the configuration and font.

macOS

On Mac hardware, shortcuts sit a bit closer to the main keys. Option plus hyphen usually inserts an en dash, and Option plus Shift plus hyphen usually inserts an em dash. The exact layout can vary slightly by keyboard region, so a quick test in a text editor helps.

Mac users can also open the Character Viewer from the menu bar, search for “dash,” and insert en or em dashes from the symbol list. This method works in almost any application that accepts text input.

Phones And Tablets

Phone keyboards hide advanced punctuation behind long presses. On many iOS and Android keyboards, pressing and holding the hyphen key displays extra options. Swiping to the longer dash characters lets you drop an en dash or em dash into a message or note.

Some note apps and word processors on mobile devices also replace double hyphens with an em dash automatically. If your text later moves into design software, these automatic replacements can save time because the correct code point is already in place.

HTML And Code

When you need long hyphen characters in HTML, using entities keeps the code readable. The sequence – produces an en dash, and — produces an em dash. Both map to official Unicode values in the general punctuation block.

Technical references from organizations such as Unicode list the dash characters with names like “En Dash,” “Em Dash,” and “Figure Dash,” which gives a clear answer when somebody asks about the long hyphen in a digital context.

Style Rules For Long Hyphen Usage

Once typing is under control, the next question is how to use these longer dash marks without confusing readers. The good news is that major style guides agree on the main patterns, even if small details differ from one region to another.

A helpful habit is to pick one style manual early, such as a house guide for a school or publisher, and read its section on hyphens and dashes closely. That single source then acts as your referee when two dash choices seem possible in the same place.

Spacing Around The Em Dash

Many American style references recommend em dashes without spaces on either side, as in “The result—though unexpected—still made sense.” British house styles often prefer a spaced en dash for that kind of break: “The result – though unexpected – still made sense.”

Whichever style you follow, the basic rule is consistency. In one document, stick with either tight em dashes or spaced en dashes rather than mixing them. Readers adapt quickly as long as the pattern stays steady from page to page.

Ranges, Relationships, And Breaks

To keep punctuation clear, use the hyphen for simple compounds, the en dash for ranges and some connections, and the em dash for sentence breaks. Thinking in terms of job rather than shape keeps your choices clean even when fonts change.

Style manuals from major publishers describe this division of labor in similar ways, and grammar references walk through examples of each symbol at work in sentences and lists.

Writing Task	Recommended Mark	Example
Compound adjective	Hyphen	Well-known author
Number range	En dash	2019–2023
Page range	En dash	Pages 10–18
Sentence break	Em dash	The decision—though late—helped.
Strong aside	Em dash	The plan—if approved—starts today.
Minus in math	Minus sign	5 − 3 = 2
Phone number alignment	Figure dash	555‒0199

Common Mistakes With The Long Hyphen

Because keyboards make the hyphen-minus the easiest choice, many documents use that small mark in places where a dash would be clearer. Over time this habit hides the difference between hyphen, en dash, and em dash, and it feeds the idea that the long hyphen is some mysterious extra symbol.

One frequent error appears in number ranges such as “10-18.” In running text the en dash is the standard mark for a range, so “10–18” reads better in formal work. Another habit swaps em dashes in for hyphens inside prefixes, which can leave a sentence looking uneven.

Doubling the hyphen to imitate an em dash is another leftover from older typewriter habits. In plain text email this may still be fine, yet in formatted documents a true em dash gives a cleaner result and avoids confusion with minus signs or figure dashes.

Copying text between programs can also mangle dashes, because some apps replace every long mark with a basic hyphen during export. When you paste material from a PDF or website into a word processor, a quick scan for number ranges and strong pauses helps you restore en and em dashes where they belong.

Main Points About The Long Hyphen

When someone asks, what is the long hyphen called, the safest answer is “em dash,” while also noting that people sometimes use the phrase for the en dash as well. Both marks are dash characters of different lengths, and each one has a specific role.

Short hyphens connect small units, en dashes show ranges and some relationships, and em dashes add punchy pauses or set off strong asides. Once you learn these names and jobs, you can spot them quickly in books, articles, and online text.

Armed with that knowledge, you no longer have to call it the long hyphen. You can choose the correct symbol, name it confidently in notes and assignments, and match the expectations of editors, teachers, and style guides.
