It sounds like a primary school drill, doesn't it? "The C Words." You might be thinking of the "Seven Cs of Communication" or perhaps the "Four Cs of Marketing" that were drilled into your head during a sophomore year business seminar. Honestly, most people hear these terms and immediately tune out because they sound like corporate fluff designed to fill up a PowerPoint slide. But here’s the thing: in the mess that is 2026—with AI everywhere and human attention spans shorter than a TikTok clip—the actual "C words" are the only things keeping brands from sinking into total obscurity.
Words matter. Specifically, the ones that start with C.
If you’re looking for a definitive list of what are the C words that actually move the needle, you have to look past the textbooks. We aren't just talking about "Communication" in a vacuum. We’re talking about the specific pillars of strategy that dictate whether a person trusts you or ignores you. It’s about clarity. It’s about consistency. It’s about a few other things that most managers skip because they’re too busy looking at spreadsheets.
The Pillars You Actually Need to Care About
Most experts point back to Scott Cutlip and Allen Center’s 1952 book, Effective Public Relations. They pioneered the Seven Cs. But let’s be real—1952 was a long time ago. The world has changed. While the core remains, the application has shifted.
Clarity is the King of the Hill
If people don't get what you're saying in three seconds, you've lost. Period. Clarity isn't just about using simple words; it's about eliminating the "noise" that surrounds your message. Think about the last time you read a "Terms of Service" agreement. That is the opposite of clarity. When we ask what are the C words that drive success, clarity is always the starting point. You want to use specific, concrete language. Instead of saying "our solution facilitates synergistic transitions," just say "we help you switch software without losing your data."
See? Much better.
Why Consistency is Harder Than It Looks
Everyone talks about consistency, but almost nobody does it well. It’s boring. Doing the same high-quality thing every single day is a grind. But look at brands like Patagonia or even creators like Marques Brownlee. You know exactly what you’re getting every time they post or release a product. That’s the "C" that builds equity. If you’re a "thought leader" on LinkedIn but you only post once every three months when you’re feeling inspired, you don’t have consistency. You have a hobby.
The Marketing Mix: The Four Cs
In the 90s, Robert Lauterborn decided the old "Four Ps" (Product, Price, Place, Promotion) were too focused on the business and not enough on the human. He proposed the Four Cs. This is where the conversation about what are the C words gets interesting for entrepreneurs.

- Consumer Wants and Needs: You aren't selling a product; you’re solving a problem.
- Cost: It’s not just the price tag. It’s the time it takes to buy it, the gas to get there, and the emotional tax of changing a habit.
- Convenience: If I have to jump through hoops to give you money, I’ll go to your competitor.
- Communication: This is a two-way street. It’s not a megaphone; it’s a telephone.
People often confuse "Promotion" with "Communication." Promotion is manipulative. Communication is cooperative. Huge difference.
The Seven Cs of Communication (The Classic List)
If you’re studying for an exam or trying to fix a broken corporate culture, these are the traditional Seven Cs. They’re a bit dry, but they work.
- Completeness: Does the listener have all the facts they need to take action?
- Conciseness: Can you say it in fewer words? If yes, do it.
- Consideration: This is basically empathy. You have to step into the shoes of the person reading your email.
- Concreteness: Use facts and figures. Don't say "we had a lot of growth." Say "we grew 42% in Q3."
- Courtesy: Being a jerk is bad for business. Shocking, I know.
- Clearness: Similar to clarity, focusing on one specific goal per message.
- Correctness: Check your grammar. Check your facts.
The "C Words" Nobody Talks About (But Should)
There are a few "C" words that don't make it into the textbooks because they’re a little too "raw" for a boardroom. But honestly? These are the ones that actually determine if you’ll stay in business for the next decade.
Curiosity
If you stop being curious about your customers, you’re dead. Blockbuster stopped being curious about how people wanted to watch movies. Kodak stopped being curious about digital sensors. Curiosity is the insurance policy against irrelevance.

Courage
It takes a lot of guts to say "no" to a bad client or a mediocre idea. Most businesses die from indigestion, not starvation. They take on too many things. Having the courage to stay focused on your "C" pillars is what separates the greats from the "also-rans."
Connection
We are lonelier than ever. Technology was supposed to connect us, but it often just buffers us from real interaction. The "C word" that really matters in 2026 is genuine human connection. Can your brand make someone feel seen? That’s the secret sauce.
Common Misconceptions About These Frameworks
A lot of people think that if they just check the boxes on a list of "C words," they’ll magically be successful. It doesn't work like that. You can be clear, concise, and correct, but if you’re boring, no one will care.
The biggest mistake? Treating these like a checklist rather than a philosophy.
Take "Conciseness" for example. Sometimes, being too short makes you sound blunt or rude. You have to balance it with "Courtesy." It’s a dance. You can’t just lean on one "C" and ignore the rest. If you're super "Clear" but totally "Inconsistent," people will think you're a flake.
Actionable Steps to Audit Your Own "C Words"
If you want to actually use this information rather than just reading it and forgetting it, do this:
- Audit your last 5 emails. Are they concise? Or are you rambling because you didn’t take the time to edit?
- Check your website’s "Above the Fold" content. Is it clear? If a five-year-old looked at your homepage, would they know what you do?
- Evaluate your consistency. Pick one platform—LinkedIn, a newsletter, a podcast—and commit to a schedule you can actually keep. If that's once a month, fine. Just don't miss.
- Practice Concreteness. Stop using words like "very," "really," "awesome," and "innovative." Replace them with data or specific descriptions.
The "C words" aren't just an academic exercise. They are the fundamental building blocks of how we interact with each other. In a world full of noise, the person who can be clear, consistent, and courageous is usually the one who wins. It’s not about memorizing a list; it’s about changing how you show up in the room. Be the person who provides clarity when everyone else is providing confusion. That is how you become indispensable.
