What does CW stand for? That hinges on where the two letters turned up. On social posts and in group chats, CW usually stands for content warning, a short heads up that a post mentions something upsetting. In TV listings, The CW is a broadcast network whose name comes from its two parent companies, CBS and Warner Bros.
Those are the two meanings most people are looking for, but the letters do plenty of other work. On a diagram CW means clockwise. In a work note it can mean coworker. In a radio shack it means continuous wave, the signal used for Morse code. The sections below sort them out.

What does CW stand for in a post or text?
Online, CW means content warning. A writer puts it at the top of a post, a video caption or a book review so readers can choose whether to keep going. It is usually followed by a short note about the topic.
A caption: "CW: hospital stay, needles. Long post about my surgery and recovery." The writer is letting readers who are uneasy around medical details skip it or come back later.
CW is close to TW, short for trigger warning. Many people use CW as a gentler, broader label for any sensitive subject, from food and weight to violence or grief, and save TW for content that might set off a strong reaction. In practice the two are often used interchangeably.
What does the CW stand for on TV?
The CW is an American broadcast television network that started in the mid 2000s, when two smaller networks were merged into one. The name joins the first letters of the two companies behind it:
| Letter | Company |
|---|---|
| C | CBS |
| W | Warner Bros. |
Ownership of the network has changed since its launch, but the name has stayed the same. Today the letters work as a brand rather than a description. People say "the C W" and usually keep the word "the" in front.
Other CW meanings by context
| Setting | CW means | Example |
|---|---|---|
| Diagrams, tools, math | Clockwise | "Turn the valve CW to close it." |
| Office notes and texts | Coworker | "My CW is covering my shift." |
| Ham radio | Continuous wave, used for Morse code | "He makes CW contacts every night." |
| Military and history | Chemical warfare | "The unit trained in CW defense." |
| School | Classwork or coursework | "CW is 40 percent of the grade." |
On a wrench or a faucet guide, look for its partner CCW, counterclockwise. In US history class, CW may also stand for the Civil War in shorthand notes.
How to write and say CW
Say each letter, "see double you." Use capital letters and skip the periods. As a post label, it is usually followed by a colon and the topic: "CW: loss." For the network, write The CW with a capital T when it is part of the name. The letter C sounds like "see," so you would type "a CW goes at the top."
- "Please add a CW before the photos."
- "That show moved to The CW last fall."
- "Tighten the bolt a quarter turn CW."
- "Asked my CW to swap Friday with me."
