Grammar and Usage
Inform is primarily a verb. In its common sense, it means giving someone information.
Inform someone of something
This is a common formal structure:
We informed the customer of the decision.
Inform someone about something
This is also common:
The teacher informed students about the schedule.
Inform someone that…
Use that when introducing a statement:
She informed us that the meeting had been canceled.
Keep someone informed
This means continuing to provide someone with relevant information:
Please keep me informed about any changes.
Be informed about/of
This passive structure means that someone has received information:
Employees were informed of the new policy.
These patterns are especially useful in professional and formal writing.
Inform can also mean “influence”
There is another important use of inform: something can inform a decision, opinion, approach, or work. Here, it means that information, ideas, or experience help shape something.
- Research informed the team’s decision.
- Her experience informed her approach to teaching.
This sense is different from simply telling someone something. Cambridge’s Business English definition specifically includes the sense of influencing a choice, decision, or behavior.
Common Mistakes
1. Using “inform” when “tell” sounds more natural
❌ Inform me what happened.
✅ Tell me what happened.
Or:
✅ Inform me about what happened.
2. Confusing “inform” and “advise”
Advise can mean inform, but it can also mean recommend.
We advised him of the changes.
We advised him to wait.
The meanings are different.
3. Using “notify” for casual conversation
Notify can sound unnecessarily official.
❌ I’ll notify my friend that I’m running late.
✅ I’ll let my friend know that I’m running late.
4. Treating “update” as a perfect synonym
Update normally suggests new information.
She updated me on the project.
This is more specific than simply saying:
She informed me about the project.
5. Confusing “inform” with “announce”
Announce generally emphasizes making something known publicly.
The company announced the new product.
It does not always work where inform means privately giving information to one person.
6. Overusing formal alternatives
Words such as apprise and acquaint can make simple sentences unnecessarily formal.
Please let me know if you have questions.
is usually more natural than:
Please apprise me should you have any questions.
7. Forgetting the correct preposition
Common patterns include:
- inform someone of something
- inform someone about something
- inform someone that something happened
Commonly Confused Words
Inform vs. Information
Inform is a verb.
Please inform the team.
Information is a noun.
Please provide the team with the information.
Inform vs. Informed
Inform means to give information.
Informed can describe someone who has enough knowledge about a subject.
The report informed the public.
The public became better informed.
Inform vs. Influence
In the phrase “inform a decision,” inform can mean influence or shape a decision through information.
The research informed our decision.
It does not simply mean:
The research told us the decision.
When Not to Use an Alternative
Sometimes inform is the clearest choice.
Use inform when you want a neutral, professional verb for giving information without adding a more specific meaning.
For example:
The company informed employees about the policy.
Changing this to briefed, notified, advised, or updated may subtly change the meaning:
- notified → emphasizes official notice
- briefed → emphasizes a focused explanation
- advised → may suggest guidance or recommendation
- updated → emphasizes new information
- announced → emphasizes public disclosure
- alerted → emphasizes urgency or potential danger
This is why a thesaurus replacement is not always an improvement. The most natural word depends on the exact meaning you want.
Writing Tips
Use “tell” for natural everyday English
If your sentence is conversational, tell is often the simplest choice.
Tell me when you’re ready.
Use “notify” for official communication
We will notify you of the outcome.
This works well for businesses, schools, organizations, and formal notices.
Use “update” for progress
Please update me on your progress.
This is more precise than inform me about your progress when you are asking for the latest developments.
Use “brief” for essential information
The director briefed the team before the meeting.
This suggests that the team received the key facts they needed.
Use “let someone know” for a friendly tone
Let me know if you need help.
It is usually more natural than inform me if you need help.
Keep “inform” in formal and professional writing
Inform is useful when you want a neutral, professional tone without implying that the information is urgent, public, new, advisory, or especially detailed.
