Avoid Making these Common Errors in English Expressions

Communication, Micro‑Signals & Language•3 min read•June 2026

You can have a brilliant strategy…

You can have years of leadership experience…

One minute you command the room and the next your authority slips.

All it takes is a single misplaced expression to distract your audience from your message and damage your confidence.

In executive communication, credibility is partially constructed from linguistic cues, which contribute to your overall professional image. Some focus on grammar and pronunciation, but few are able to pick up on the misused expressions that quietly erode confidence in what they're saying.

That being said, if a colleague misuses an expression, it’s always best to provide feedback in a constructive way.

As in most languages idioms may not actually be logical e.g. “no smoke without fire (dry ice!)”. They will however be standardised, native and non-native speakers all run the risk of learning incorrect idioms.

Here are just 6 common errors made by native and non-native speakers alike:

"Across the piste"
Many people say "across the piece,", as an alternative to, "across the board.". Others use it with the expression "across the piste," borrowed from skiing terminology. The result is often an expression that sounds familiar but isn't quite right.

"Deep-seeded issue"
The correct expression is a deep-seated issue. A problem is "seated" firmly in place, not "seeded." A seed suggests it can still be removed fairly easily.

"For all intensive purposes"
To me, this sounds like an oddly-phrased claim that you’d find on a tube of superglue. This is a common mistaken phrases in business English. The correct expression is for all intents and purposes, which means "effectively" or "in practice."

"One fowl swoop"
The phrase is in fact one fell swoop, meaning a single, sudden action. In contrast, a fowl swooping is not a very sudden action. The expression dates back centuries and was popularised by Shakespeare.

"Case and point"
The correct form is case in point, meaning an example that illustrates the argument being made. Case and point sounds like case is distinct from the point.

"Damp squid"
The correct phrase is damp squib. A wet squid is not inherently disappointing, whereas a damp squib is a small firework that can’t light, falling below expectations.

Moving Past the Dictionary

Why does this matter?
Expressions are unavoidable in speech. Not only are they enhancers of cohesion, but they also demonstrate cultural literacy- which is essential in global business.

Senior leaders are judged not only on what they know, but on how they communicate. When executives are presenting to clients, investors, boards, or international teams, these details make the difference between sounding like your average post-truth politician and being a great orator.

Attentive listeners pick up on misused expressions, which signal that the person absorbs second-hand information without verifying, relying on what they learned by ear. In the world of generative A.I, ensuring the accuracy of the information one receives is more important now, than ever, in business.
