The Slash

Punctuation Marks

Part 13

The Slash


What is a slash? When should a slash be used? How should a slash be used in a sentence? These are a few of the questions this workshop will answer. (Please see the punctuation chart in our introduction to punctuation workshop).


The slash is a forward sloping line (/) that serves as a mark of punctuation. Once used to mark periods and commas, the slash is now most often used to represent exclusive or inclusive; division and fractions; and as a date separator. Also called a virgule, oblique, an oblique stroke, a diagonal, a solidus, a forward slash, and a separatrix.

Common uses:

Use 1- Signify alternatives (and/or)

The use of slashes tend toward informal pieces of writing. They’re sort of like an illustration of the word “or.”

For example:

• At last week’s speed dating event, there were instructions for every man/woman to stick to a three-drink maximum.

• The professor instructed all students to bring a notebook and/or laptop to class to take notes.

• If/when the professor shows up, I’m sure it’ll be a great class.

Use 2- Dates

You can write out December 25, 2025, or you can write shorten it to 12/25/2025, or even 12/25/25.

Even though it’s true that slashes are used informally, many formal writings will accept a forward slash when dealing with dates.

Just be careful because some methods of citation might prefer a hyphen (-). So, for example, you may be required to write 12-25-2025. It’s always worth the extra ounce of effort to check and double-check the preferred method of citation.

Use 3- Separate lines in a poem

Mary had a little lamb/ little lamb, little lamb/ Mary had a little lamb/ whose fleece was white as snow.

The quality of mercy is not strained/ it droppeth as the gentle rain from heaven/ upon the place beneath. It is twice blest:/ It blesseth him that gives and him that takes

Use 4- Abbreviation

For example:

• Look out for the package we sent you c/o (care of) Jane Smith.

• Remember to take your notebook w/you (with you) when you leave today.

• The house was unbearably hot as the a/c (air conditioning) was broken.

Did you notice that each of these examples has an air of informality? You’d never write “w/you” in an academic paper. However, in less formal settings, forward slashes help us shorten our writing.

Use 5- Replace the word per

For Example:

Mary’s job pays her a salary of $800/week.
A police car tops out at a speed of 250 km/h.

Use 6- Conflicting Ideas/Relationships

In its truest form, a slash is either going to indicate a connection between two things or a conflicting idea/relationship.


Let’s say we were planning a trip to the moon and we wanted to make a connection between our charted courses. Our resident astronaut might say, “In order to make a successful landing on the moon, we’re going to take the Mars/Venus route into space.”

In this example, the slash is acting as a connector between two distinct locales that are both a part of our charted course.

Special note:

Only use a space after the / (before a word) when using in music/poems.  All other instances there is no space before or after the /.
