What Is This “/” Called? | Slash Name And Rules

You see “/” everywhere: URLs, dates, math, file names, and short labels like yes/no. When you need to describe it in a sentence, it’s easy to freeze for a second. That’s usually when the same question pops up: what do I call this mark?

If you searched for what is this “/” called?, you’re in the right place. This article gives you the names people use, what each name suggests, and the writing rules that keep slashes readable.

Names For The “/” Symbol At A Glance

In everyday writing, slash is the standard name. In tech, you’ll often hear forward slash to separate it from the backslash character “\”. In typography and character naming, you may run into solidus. In publishing talk, virgule can show up when “/” marks a line break in verse quoted on one line.

Where You See It	What People Call It	What That Name Signals
Everyday writing	Slash	Plain, common term for “/”.
URLs and web pages	Forward Slash	Helps avoid mix-ups with “\”.
Character sets and code charts	Solidus	Formal label used in many technical references.
Poetry line breaks typed inline	Virgule	Marks a line break when line layout can’t be kept.
Fractions styled as stacked numbers	Fraction Slash (⁄)	A separate character that’s narrower in many fonts.
Division operator look-alike	Division Slash (∕)	Another related character used in some math fonts.
Speech sounds in linguistics	Slashes	Pairs of slashes can bracket phoneme-style transcriptions.
Scores and totals	Slash	Often read as “out of,” like 17/35.
Units	Slash	Often read as “per,” like km/h.
Programming	Slash	May mean division, comment markers, paths, or patterns.

What Is This “/” Called? In Grammar And Typography

In plain English, it’s a slash. That’s the safest word to use in school, at work, and in day-to-day writing.

If you’re dealing with font files, character tables, or Unicode names, you may see the term solidus. It’s the same “/” character you type on a keyboard, just labeled with a formal name.

Slash Vs Backslash

These two marks look like siblings, but they’re not interchangeable. The slash leans forward: “/”. The backslash leans back: “\”.

In many contexts, switching them changes the meaning. A URL with the wrong slash can fail to load. A file path with the wrong slash can point to nowhere.

Forward Slash As A Clarity Cue

People say “forward slash” most often in two moments: when they’re giving typing instructions and when backslashes might appear in the same set of steps.

If you’re writing directions, naming the character before showing it cuts confusion. That approach lines up with Microsoft’s guidance for user instructions in its Slashes style page.

How To Type The Slash On Common Keyboards And Phones

Typing “/” is easy until you’re helping someone else find it. A quick description can save a lot of back-and-forth.

On A Windows Or Mac Keyboard

On most keyboards, the slash sits on the same button as the question mark. It’s usually near the right Shift. Press the button for “/”, then add Shift for “?”.

The backslash sits on a different button and can be near Enter. That’s a common source of mix-ups when someone is copying a file path from a screenshot.

On A Phone Or Tablet Keyboard

On touch keyboards, the slash is usually on the symbols page. Tap “?123” or “123”, then look for “/”.

If you’re sharing a URL by text, copying and pasting is safer than typing it character by character. One missed slash turns a good link into a dead end.

When A Slash Works Well In Writing

A slash earns its spot when it saves space and the meaning stays sharp. It fits best in labels, notes, tables, and short phrases.

Here are the common uses where readers rarely get stuck.

Short Alternatives In Labels

Slashes show quick choices in headings and form fields: yes/no, true/false, pass/fail. In that role, the mark acts like a divider.

In a full sentence, the same pattern can feel vague. If your reader must know whether you mean “and,” “or,” or “either,” words usually read better than a slash.

Abbreviations And Shorthand

You’ll see slashes in shortcuts like w/ (with) and w/o (without). These are common in notes and casual messages.

In formal writing, abbreviations can distract. If the piece is meant to be polished, writing the full word keeps the tone steady.

Fractions, Ratios, And Scores

In plain text, a slash can stand in for a fraction bar: 1/2, 3/4, 9/10. In scores, it often reads as “out of,” like 18/20.

When a line includes several fractions or variables, add parentheses so the reader doesn’t have to guess grouping, like (a/b)/(c/d).

Units As “Per”

In science and daily life, a slash can mean “per,” like km/h, m/s, or calories/day. This is compact and widely understood.

If a unit already has a slash inside it, avoid stacking more slashes. Switching to words or parentheses keeps the unit readable.

Dates And Numeric Formats

Dates like 12/21/2025 are common in U.S. usage. In many other regions, the order flips, so the same digits can point to a different day.

If your audience spans more than one region, writing the month as a word (21 Dec 2025) or using an ISO-style date (2025-12-21) avoids mix-ups.

When To Skip The Slash And Use Words Instead

A slash can be a neat shortcut, but it can also blur meaning. If a reader might pause and reread, that’s your cue to switch to words.

Ambiguous Pairings

Pairs like “male/female,” “parent/guardian,” or “student/teacher” can mean several things: a choice, a combined category, or a label. Without extra context, readers may guess wrong.

If you mean a choice, use “or.” If you mean both groups, use “and.” If you mean a category label, rephrase it as a noun, like “student and teacher roles.”

Long Phrases On Both Sides

When each side of the slash is a multi-word phrase, the line can start to feel like compressed notes. At that point, punctuation won’t fix the clarity problem.

Try a short rewrite: “Choose New Zealand or Western Australia for this leg of the trip.” The reader gets the meaning without decoding shorthand.

Formal Sentences With Legal Or Policy Meaning

In legal or policy text, tiny wording choices can change interpretation. A slash can hide that difference, since it doesn’t say whether the items are linked or separate.

If the stakes are real, spell out the relationship in words. Your reader shouldn’t have to guess what the slash stands for.

Slashes In URLs, File Paths, And Tech Text

Computing is a big reason “slash” became the default name. We type it in URLs, commands, and code all the time.

The generic URI standard treats “/” as the separator between path segments in many web pages. You can see that rule in RFC 3986, which defines the generic URI syntax used across the web.

Web Pages And Paths

In a URL, the slash works like a divider. It separates parts of the path, like /blog/grammar/slash.

Double slashes also appear after the scheme in many URLs, like https://. That pattern is normal. Still, extra slashes inside the path can change what page you land on, depending on the site’s routing.

File Paths On Different Systems

Many systems use the forward slash in file paths, like /home/user/file.txt. Windows often uses backslashes, like C:\Users\Name\Documents.

If you’re writing steps, show file paths in a monospaced style (like code formatting in your editor) so slashes stand out and copying is easier.

Programming Meanings You’ll See Most

In code, “/” can mean division. Two slashes (//) can start a comment in many languages. In some tools, slashes bracket patterns or act as separators inside commands.

When you teach beginners, name the character (“slash”) and show the exact symbol. That keeps it separate from similar shapes like “1”, “l”, and “\”.

Typography And Spacing Rules For Slashes

Most of the time, you don’t add spaces around a slash in short pairs like and/or, km/h, or 10/10. Tight spacing signals that the pair is meant to be read as one compact unit.

Spaces can make sense when each side is long or already contains spaces. A spaced slash can help the eye separate two chunky phrases without turning the line into a wall of text.

Watch out for line breaks. If a slash lands at the start of a new line, the reader can miss the left side. Use a nonbreaking space before a spaced slash, or rewrite the line so the two parts stay together when you paste into slides.

Consistency Matters More Than Style Tricks

If you use slashes in labels, keep them consistent across the page. Mixing “and/or”, “and / or”, and “and-or” on the same page can make the writing feel messy.

Pick one pattern that fits the context, then stick with it. Your reader will stop noticing the punctuation and stay focused on the meaning.

Slash In Quoted Verse On One Line

When you need to show a line break in verse while keeping text on one line, a spaced slash is a common choice: first line / second line.

This is where “virgule” is most likely to appear as a label in publishing talk. Use it only when line breaks matter and you can’t keep the original line layout.

Quick Reference Table For Common Slash Uses

This table gathers the writing scenarios where slashes show up most often, plus spacing notes and a clean model line for each.

Use Case	Spaces?	Model Line
Simple alternatives in labels	No	yes/no question
Abbreviations in notes	No	w/ notes
Fractions or scores	No	8/10 score
Units read as “per”	No	km/h speed
Dates in a single region	No	12/21/2025
Two long phrases	Sometimes	New Zealand / Western Australia
Verse line breaks inline	Yes	first line / second line
URLs	No	https://site.com/a/b
Unix-style paths	No	/home/user/docs

What To Say Out Loud When You See “/”

In conversation, “slash” is the default. If you’re reading a URL aloud, “slash” still works and most people will follow.

If you’re guiding someone through typing, “forward slash” reduces mix-ups with backslash. In math, many people say “over” for a fraction like 1/2 and “per” for units like km/h.

Final Check: Picking The Right Name

So, what is this “/” called? Most of the time, it’s a slash. In tech steps, “forward slash” is clearer when backslash might appear. In character naming and typography references, “solidus” is a common label.

If you match the name to the setting and keep the meaning clear, the slash does its job and the reader doesn’t stumble.
