People who try too hard to sound smart tend to use these 10 fancy phrases, says communication expert

Some people have a natural way with words. Others resort to puffed-up vocabulary, sprinkling their speech with sophisticated-sounding phrases that often come off as more awkward than impressive.

It’s not always intentional — sometimes they’re genuinely excited to demonstrate knowledge or polish.

Yet, when forced, it can ring hollow.

Below, I’ll highlight ten of the most common “too fancy” phrases people use when they’re trying a bit too hard to look intellectually superior.

1. “Irregardless”

You might hear this in a debate or a team meeting: “Irregardless of the circumstances…”

The problem? Irregardless isn’t really standard English — the correct term is just regardless.

Folks who say irregardless often assume it adds weight or authority, but most language buffs see it as a red flag that someone’s straining to sound knowledgeable.

If you catch yourself wanting to say irregardless, consider swapping in regardless or despite that.

You’ll sound a lot clearer—and trust me, no one will question your smarts for using simpler language.

2. “Henceforth”

“Henceforth” probably had its heyday in formal letters centuries ago.

Now, you’ll occasionally hear it in a speech or a stuffy memo: “Henceforth, we shall proceed with the new policy.” It’s not wrong, but it feels archaic outside of legal documents.

Using it in casual conversation often lands awkwardly.

If you want to indicate something will apply from now on, stick with direct wording like from now on or going forward. You’ll avoid the Shakespearean vibe that can distract from your actual point.

3. “Utilize”

This is a classic example.

Many people think utilize is just a more intelligent way to say use. It might have a subtle nuance in certain contexts (like turning an object to a purpose different from what it was intended for), but in most everyday settings, use works perfectly fine.

Dropping utilize into every other sentence is a giveaway that you’re trying to sound more sophisticated than you need to be.

For instance, “We need to utilize our resources effectively” could simply be “We need to use our resources effectively.”

Trust me, it saves you a syllable or two and keeps your communication crisp.

4. “Per se”

“Per se” translates to “by itself” or “intrinsically.” Some folks sprinkle it anywhere they want to appear learned—like “I’m not criticizing your idea per se, but…” If used sparingly, it can be effective.

Overuse, though, usually raises eyebrows.

When you’re about to say per se, ask yourself if you can replace it with a simple phrase like itself or exactly.

In many cases, that small edit can make your sentence more direct and less pompous.

5. “In lieu of”

In formal writing or legal contexts, “in lieu of” can serve a purpose (it means “in place of”).

But in casual conversation, it’s easy to come across as pretentious:

“Let’s meet at the café in lieu of the office.”

You’re not likely to impress many people by dropping “in lieu of” every chance you get.

If you want to sound natural, replace it with “instead of.”

Simple and crystal clear.

There’s no need for the extra flourish unless the setting legitimately calls for it.

6. “Synergy”

I can’t tell you how many times I heard “synergy” during my brand strategy days. This buzzword popped up in pitch meetings, corporate newsletters, and company retreats.

Synergy means different parts working together to create a bigger impact than they would alone. Yet, it’s been so overused that it often feels like empty corporate jargon.

If you’re genuinely talking about collaboration, just say so.

Say we’re working together for a stronger outcome or joining forces.

That’s usually enough. Throwing “synergy” into every brainstorming session can come off as trying to sound hip and forward-thinking, even when the concept itself is plain teamwork.

7. “Heretofore”

Another relic from old legal documents, “heretofore” stands out in everyday language because hardly anyone uses it naturally. It means until now or before this point.

Usually, you’ll hear it in ultra-formal statements like, “This practice was heretofore unacceptable.”

But in a modern context—especially in spoken conversation—it’s jarring and can make the speaker sound like they’re reciting from a century-old textbook.

If you need to refer to something that happened up to this moment, a phrase like “up until now” is straightforward. Save “heretofore” for formal legal arguments or historical novels if you truly want that vibe.

8. “Moreover”

This word does show up in academic papers to link ideas.

But in casual conversations, it might come across as stiff.

People drop “moreover” when they want to stack an additional point on top of another, often in an attempt to appear polished. A direct alternative is “also,” “further,” or “plus.”

I’ve heard “moreover” used repeatedly in team updates or office memos—without any real gain in clarity. If your listener is used to a simpler flow, “moreover” can sound like a forced attempt to elevate your speech.

9. “Incontrovertible”

This one means something can’t be disputed or argued against. It’s a hefty word that can land with a thud in everyday dialogue.

When a person insists something is “incontrovertible,” they’re basically saying, This is beyond question, which can sound a bit authoritarian if you’re not in a legal or scientific context.

Try “undeniable” or “can’t be argued.” They carry the same meaning without the heavy flourish.

Unless you’re in a formal debate, keep it friendly and straightforward.

10. “Posthaste”

Straight out of a Dickens novel, “posthaste” means you’ll do something with great speed. Someone might say, “I’ll send over the documents posthaste,” hoping to emphasize urgency.

In reality, though, you can just say “right away” or “as soon as possible.”

Dropping “posthaste” into casual conversation or even business emails often reads like you’re playing at old-fashioned drama.

Outside of certain historical or comedic contexts, “posthaste” can feel like an overblown attempt to sound urgent or refined—an attempt that frequently backfires.

Conclusion: Clarity over complexity

There’s nothing wrong with using a robust vocabulary. Expanding your word choices can elevate writing, public speaking, or any situation where you want precision.

The challenge is striking the balance between clarity and ostentation.

When used sparingly and with purpose, fancier words can drive a point home. But when folks stuff them into every sentence just to seem intellectual, it often produces the opposite effect.

If you recognize yourself dabbling in these phrases—or if you hear them in your circles—don’t stress. Sometimes we all get carried away, especially if we’re excited or nervous.

A little self-awareness can help you communicate more authentically. After all, there’s real power in simplicity when it comes to making your message stick.

Here’s to your next step forward.
