21 Everyday English Mistakes Professionals Make And What to Say Instead

You don’t sound unprofessional at work because your English is bad.
You sound unprofessional because you’re using technically correct but practically weak English.

Mistake 1 is using I am having for permanent situations.
Wrong: I am having five years of experience.
Correct:  have five years of experience.
Logic: Having” is temporary. Experience is permanent.

But, remember, we can use having while consuming something…Which is a temporary situation…So, you can say…I am having my lunch right now…But not….I am having enough vegetables in my stock.

Simple hack; Avoid having for possession & use having for consumption.

Mistake 2 is saying I will revert back to you.
Wrong: I’ll revert back to you by tomorrow.
Correct: I’ll get back to you by tomorrow.” Or “I will revert by tomorrow.
Logic: “Revert” already means “go back.” “Back” is unnecessary and sounds dated.
Professional English values precision, not repetition.

Mistake 3 is overusing ‘actually’ to sound confident.
Wrong: Actually, I think this approach is better.
Correct:I think this approach is more effective.
Logic: Actually” weakens your sentence unless you are correcting a fact.
Some common filler words are actually, basically, like etc.. Some professionals use some phrases to fill the pause They speak ‘You know’ a lot

Mistake 4 is starting sentences with ‘As per my understanding’.
Wrong: As per my understanding, the deadline is Friday.
Correct: My understanding is that the deadline is Friday.
Logic: “As per” is used for documents, not opinions.

Mistake 5 is saying ‘Do the needful’.
Wrong:Please do the needful.
Correct: Please take the necessary action.
Logic: Do the needful is outdated and unclear though it’s grammatically fine.

Mistake 6 is apologising unnecessarily.
Wrong: Sorry, I have a question.
Correct: I have a question.
Logic: Apologising without fault lowers your authority. It also dilutes your apology for the right cause. 

Mistake 7 is saying ‘I am not comfortable’ when you mean ‘I disagree’.
Wrong: I’m not comfortable with this idea.
Correct: I see a risk in this approach.
Logic: Comfort is emotional. Business communication is analytical.

Mistake 8 is using ‘very’ instead of precision.
Weak Sentence : This is very important.
Strong Sentence: This is critical.
Logic: Strong words beat weak intensifiers.
Senior professionals sound sharp because they choose exact words.

Mistake 9 is saying ‘I will try’.
Wrong: I’ll try to complete it today.
Correct: I’ll aim to complete it today.
Logic: Try signals uncertainty. Aim signals intent.
Intent builds trust.

Mistake 10 is translating Hindi structure into English.
Wrong: This work I will do tomorrow.
Correct: I’ll do this tomorrow.
Logic: English follows subject-verb flow, not emphasis shifting.
Translation kills fluency faster than grammar mistakes.

Mistake 11 is saying ‘I think’ too often.
Wrong: I think we should revise this.
Correct: We should revise this.
Logic: Over-qualifying weakens conviction.

Mistake 12 is using ‘discuss about’. And this is a common grammatical error.
Wrong: Let’s discuss about the plan.
Correct: Let’s discuss the plan.
Logic: Discuss” is a transitive verb in English which doesn’t require any preposition after it. It requires a direct noun.

Mistake 13 is saying ‘Please explain me’.
Wrong: Please explain me the process.
Correct: Please explain the process to me.
Logic: Explain requires a direct object after it not an indirect object. Direct objects are generally non-living objects while Indirect objects are living objects.
Small structure errors affect perceived fluency.

Mistake 14 is using ‘only’ randomly.
Wrong: He is only working here.”
Correct: He works here.
Logic: Only as an adjective is used to emphasize noun after it.
For example….I need only 100 bucks.

Mistake 15 is saying ‘Today morning’.
Wrong: Today morning we had a call.
Correct: This morning we had a call.
Logic: English time expressions are fixed. Similarly, instead of using yesterday night, say last night.
Small fixes = big polish.

Mistake 16 is ending statements with question tone.
Wrong: We can submit this today?
Correct: We can submit this today. Or Can we submit this today?
Logic:  We use specific sentence structures for specific tone. If you want to emphasize an affirmative sentence, you can use question tags.
Tone & structure, both are as important as grammar.

Mistake 17 is using ‘Myself’ incorrectly.
Wrong: Myself Vinit, handling sales.
Correct: I handle sales.
Logic: “Myself” is reflexive, not introductory.
This one mistake instantly signals non-native rigidity.

Mistake 18 is saying ‘Sir/Madam’ in global meetings. You can use Mr/ aur Ms., if needed.
Wrong: Yes sir, I will do it.
Correct: Sure, I’ll take care of it.
Logic: Global English prefers equality over hierarchy markers.
Respect is shown through tone, not titles in global meetings. One caution here- avoid Mrs. As it only refers to a married woman…You can use Ms. For both married and unmarried woman.

Mistake 19 is over-explaining simple points.
Wrong: Long justifications. Some professionals over-explain even simple things.
Correct: One clear sentence. Or use a 3-point structure.
Logic: Meetings reward clarity, not effort.
Over-explaining signals insecurity.

Mistake 20 is thinking confidence comes before speaking.
Wrong belief: I’ll speak when I feel confident.
Correct belief: Confidence comes after speaking.
Logic: Action creates confidence, not preparation.

Mistake 21 is waiting for perfect English.
Wrong: Silence.
Correct: Structured imperfection.
Logic: Fluency is built through repetition, not hesitation.
Meetings don’t reward perfect English. They reward visible clarity.

Remember – English fluency is not about sounding impressive.
It’s about sounding clear.
