Language guardrails: the words you use, the words you drop
Stories don't erode in big decisions. They erode word by word—one "simplified" term in a sales deck, one synonym in a job post, one AI draft that's almost right. Language guardrails stop that: an agreed set of words that carry your story, and the ones that quietly kill it. So the story stays yours without you proofreading everything.
THE PROBLEM
How a story dies one word at a time
Every single change was reasonable.
Nobody decides to make your story generic. A team member swaps your term for the industry standard because prospects “know that word.” A new hire describes the product the way their last company would have. An AI tool drafts something fluent that could belong to anyone. Each change is defensible on its own, and the sum of them is a company that sounds like everyone else.
This is Signature Corrosion working at the sentence level—and it’s where it does most of its damage, precisely because no single instance seems worth fighting over.
WHAT GUARDRAILS CONTAIN
Agreements, not a rulebook
Your team shouldn’t need permission to write a sentence.
The guardrails document three things. The words you use—your category language, with the reasoning behind each term, so people defend them instead of just obeying them. The words you drop—the industry vocabulary that files you next to your competitors, each with what to say instead. And the phrases for the moments that repeat: how you introduce the company, how you answer the standard objection, how you describe what you do in one line.
One more rule holds it together: metaphor consistency. If your story lives in a certain world—a journey, a foundation, a signal—every new piece of language has to be able to live there too. Mixed metaphors read as small things; they’re how coherence leaks.
WHAT YOU WALK AWAY WITH
A shared vocabulary that defends itself
- The words we use — your category language, with the why behind each term
- The words we drop — and what replaces them
- The phrase bank — ready language for the moments that repeat
- The metaphor rules — the world your language lives in, kept consistent
The test: a new hire writes their first piece in week one, and you don’t correct a single term.
Whose words is your company using right now?
Read your last three outgoing documents—deck, proposal, post. If you can’t hear yourself in them, the erosion is already underway. Guardrails are how you stop it.
