Use /j when chatting over text to convey you’re just kidding. While it’s often easier to tell if someone is joking or being sarcastic in person by their tone, it’s hard to convey tone in print or text.

Next time you want to be sarcastic or jokey on Twitter or Reddit, or over text, make sure your audience knows how to read your tone by ending your comment with “/j.”

A tone indicator is a symbol attached to a message sent in text form. For instance, a tone indicator (also called a tone tag) may be appended to a text message, email, or social media post to let the reader know how they should read your tone. It’s often easier to pick up on tone in face-to-face verbal interactions, but via print or text only, it can be much more difficult to tell if someone is joking.
- Tone indicators usually take the form of a letter or series of letters preceded by a forward slash—e.g., “/srs” (serious) or “/s” (sarcastic).
- Everyone can benefit from tone indicators online, but they can be especially helpful for neurodivergent people, especially autistic people, who may have extra difficulty interpreting tone or picking up on sarcasm.^{[1]

- That said, tone indicators aren’t only used for sarcastic content; there are tone indicators to mark all sorts of tones that may be difficult for readers to pick up on, such as romantic (“/r”) or genuine (“/g”).

Tone indicators have been around for centuries. The most popular tone indicator—“/s”—has been around for years and stems from “</sarcasm>,” a parody of an XML closing tag. However, tone indicators generally have been used for centuries: as print became more popular, so did the need for a symbol to indicate when someone wasn’t being sincere.
- Early tone indicators included the percontation point (⸮), a backwards question mark to indicate a rhetorical question, which was proposed by Henry Denham in the 1580s but which died out in the 1700s, and the emoticon “:-)” to indicate a joke (and “:-(“ to indicate something was sincere).
