7 English mistakes professionals make at work (and what to say instead)

The mistakes that trip professionals up at work aren't the ones from a grammar book. They're small, specific phrases that sound almost right — close enough that nobody corrects you, but just off enough that native speakers notice. Here are the ones that come up most often in real workplaces, with the exact fix for each.

"Actually" doesn't mean what you think

Many non-native speakers use "actually" to mean "currently" or "right now." In English, "actually" means "in fact" or "surprisingly" — it corrects an expectation. Saying "I'm actually working on that project" implies someone thought you weren't.

"I'm actually working on the migration." — This tells the listener you're correcting a misconception.

"I'm currently working on the migration." — This just states what you're doing right now.

The fix: when you mean "right now" or "at the moment," use currently or at the moment. Save "actually" for when you're genuinely correcting someone.

"I have a doubt" sounds strange in English

In Spanish and Portuguese, "tengo una duda" and "tenho uma dúvida" are perfectly natural. The direct translation — "I have a doubt" — sounds oddly philosophical in English. It implies suspicion, not confusion.

"I have a doubt about the timeline." → "I have a question about the timeline."

The words that work: "I have a question", "I'm not sure about something", or "Can I check something?" All of these sound natural in a meeting and get you exactly what you need.

"Please revert" doesn't mean "please reply"

In some workplaces, "please revert" is used to mean "please reply" or "please get back to me." In standard English, "revert" means to go back to a previous state. A native speaker reading "please revert" might think you want them to undo something.

"Please revert at your earliest convenience." → "Please let me know when you get a chance."

Alternatives that work: "Could you get back to me on this?", "Please let me know", or simply "Let me know what you think."

"Make a meeting" vs. "have a meeting"

You don't "make" a meeting in English — you schedule one, set one up, or have one. "Make a meeting" is a direct transfer from Spanish ("hacer una reunión") or Portuguese ("fazer uma reunião") that sounds off to English ears.

"Can we make a meeting?" → "Can we set up a meeting?"

The natural options: "Let's set up a meeting", "Can we schedule a call?", or "Let's find a time to meet."

"I explain you" is missing a word

In Spanish, "te explico" is one smooth phrase. In English, "explain" always needs "to" before the person: "I'll explain it to you." Dropping the "to" is one of the most common mistakes Spanish speakers make in English, and native speakers notice it right away.

"Let me explain you the process." → "Let me explain the process to you."

The same pattern applies to other verbs: "describe something to someone", "suggest something to someone." When in doubt, check if the verb needs a "to" between the thing and the person.

"Until Friday" vs. "by Friday"

"I'll finish the report until Friday" means you'll be working on it continuously until Friday arrives. If you mean the deadline is Friday, the word is "by." This one matters because it can change commitments in writing.

"Until Friday" = ongoing, continuous, from now through Friday.

"By Friday" = the deadline. It will be done no later than Friday.

"I'll send the deck until Thursday." → "I'll send the deck by Thursday."

The "the" problem

English speakers drop "the" where other languages keep it. You don't say "the life is short" — you say "life is short." But you do say "the meeting is at three," not "meeting is at three."

There is no single rule that covers every case, and even advanced speakers get caught. The pattern that helps most at work: job titles and departments don't usually take "the" when used generally ("I work in marketing," "She's in finance"), but specific groups do ("the marketing team," "the finance department").

Getting "the" right 100% of the time is genuinely hard. But even small improvements — like dropping it before abstract nouns and adding it before specific teams — make a noticeable difference.

Why these small things add up

None of these mistakes will stop someone from understanding you. That's not the point. Each one creates a tiny moment where the listener's attention shifts from what you're saying to how you're saying it. In a meeting, a presentation, or a negotiation, those moments add up.

The good news: these are habit fixes, not knowledge gaps. You already know the right form once someone points it out. The work is catching yourself before it comes out the old way — and that gets easier with practice. Even fixing two or three of these makes your English at work sound noticeably more natural.
