Why vague language undermines your authority—and what to do about it
Imagine a senior manager presenting quarterly results to the executive team. Her data are solid, and her analysis is sound. But every few sentences, she says something like: “We had some problems with vendor compliance, and people were not happy about the delays.”
Later, over coffee, a colleague would say what everyone else felt: “She sounded uncertain. Like she wasn’t in control of the situation.” The manager wasn’t uncertain.
She knew her material cold. But her word choices—”had some problems,” “people were not happy”—made her sound passive, vague, and tentative. She’d undermined her own authority without realising it.
This happens constantly in professional communication. We reach for weak, generic words because they feel safe. We say “said” when we mean “insisted.” We write “big decision” when we mean “critical decision.” We describe ourselves as “happy with the results” when we’re actually “gratified by the outcomes.” These small choices accumulate. Over time, they shape how colleagues, clients, and supervisors perceive our competence. The good news? Precision is a skill you can develop. And it starts with recognising the words that weaken your message.
The usual suspects
Certain words show up everywhere in workplace writing and speaking, and they’re almost always too vague to do the job you need them to do.
Take “said.” It’s a neutral reporting verb—it conveys no tone, no emphasis, no commitment. Compare these two sentences:
“The director said the policy would be reviewed.”
“The director insisted the policy would be reviewed.”
The second version tells you something about the director’s determination. It removes ambiguity. When you’re delivering that sentence aloud, your voice naturally firms up on “insisted.” The word demands a stronger delivery.
Or consider “big.” It’s casual and imprecise. A “big decision” could mean anything. But a “monumental decision” conveys scale and significance. A “critical decision” emphasises urgency. A “substantial decision” suggests careful weighing of options. Each alternative gives your audience more information—and signals that you’ve thought carefully about what you’re communicating.
The same principle applies to “happy.” In a professional context, “happy” can sound informal or even childish. “We’re happy with the quarterly results” lacks the weight of “We’re gratified by the quarterly results” or “We’re encouraged by the quarterly results.” The upgraded versions convey earned satisfaction and professional judgment.
And then there’s “problem.” It’s not wrong, exactly, but it can sound like complaining. “We have a problem with the budget” feels passive. “We face a challenge with the budget” frames the issue as something you’re actively addressing. “We’re confronting a crisis in the budget” escalates the urgency and demands action. Choose based on the severity and the response you want from your audience.
A word of caution
Precision doesn’t mean reaching for the fanciest word in the thesaurus. I’ve seen writers replace “use” with “utilise” or “help” with “facilitate” in a misguided attempt to sound more professional. That’s not precision—that’s pretension, and your readers will sense it. The goal is to match your word choice to the meaning you actually intend. If your team solved a minor scheduling conflict, don’t call it “a triumph over adversity.” If a client expressed mild concern, don’t write that they were “outraged.” Exaggeration damages credibility just as much as vagueness does.
Pronunciation matters, too
Here’s something most people don’t think about: even if you choose the perfect word, mispronouncing it can undercut your authority.
I’ve heard professionals stumble over words like “comparable” (it’s COM-pra-ble, not com-PAIR-a-ble), and “formidable” (in British English, for-MID-a-ble; in American English, FOR-mi-da-ble).
These aren’t obscure terms—they’re common in workplace communication. But if you stress the wrong syllable, your audience notices. They may not consciously register the error, but it creates a moment of friction. Your credibility takes a small hit. The fix is simple: when you’re preparing a presentation or an important email, read it aloud. If you stumble over a word, look up the pronunciation. Practise it until your mouth knows where the stress falls. This is especially important for words you’ve chosen specifically for impact. Nothing undercuts “formidable challenge” faster than mispronouncing “formidable.”
Try this
Open the last email or report you sent. Scan for these weak words: said, big, happy, problem, good, bad, nice, thing, got, very.
For each one, ask yourself: What do I actually mean? Then replace the weak word with a precise alternative. Don’t overthink it—just choose the word that most accurately conveys your intended meaning.
Now read the revised version aloud. Notice how your delivery changes. The stronger words will naturally command more authority in your voice.
That’s the power of precision. Your ideas haven’t changed, and neither has your expertise. But the way your message lands—with your reader, with your listener—has shifted. You sound more confident, more credible, more in command of your material. And that’s exactly the impression you want to make.
