Have you ever wanted to ask about something and stopped because you were not sure whether to say “curious of” or “curious about”?
This is a common problem for English learners. Both phrases may look possible because curious is an adjective, and learners often wonder which preposition should follow it.
The good news is that the answer is quite simple in modern English: “curious about” is the normal and natural choice when you want to say that you want to know more about something.
For example:
I’m curious about your new job.
Here, the speaker wants to know more about the new job.
You may sometimes see “curious of”, especially in older writing or unusual expressions, but it is not the normal choice for everyday English. Saying “I’m curious of your new job” sounds unnatural to most modern English speakers.
This small preposition can make a big difference in how natural your English sounds. It matters in conversations, emails, school writing, workplace communication, and everyday questions.
By the end of this guide, you will know why “curious about” is correct, when to use it, what other structures can follow curious, and how to avoid the most common mistakes.
4. What Does “Curious” Mean?
The word curious is an adjective. It usually describes someone who wants to know, learn, or understand something.
If you are curious, you have a strong desire to get information about something.
For example:
- I’m curious about her new project.
- He is curious about how the machine works.
- The children were curious about the strange noise.
- She became curious about her family history.
- Are you curious about what happened?
- My friend is curious about life in another country.
- I’m very curious about your opinion.
- They were curious about the reason for the change.
In all these examples, curious about means that someone wants to know more.
The basic grammar rule
The most common structure is:
subject + be + curious + about + noun/pronoun
Examples:
- I am curious about the answer.
- She is curious about your plan.
- They are curious about the new teacher.
You can also use a question word or clause after about:
curious about + what/why/how/where/who + clause
Examples:
- I’m curious about what she said.
- He is curious about why they left.
- We’re curious about how it works.
- She is curious about where he went.
This structure is extremely useful in natural English.
What does “curious” really express?
Being curious does not always mean that you are asking a direct question. It can simply show that something has caught your attention.
For example:
I’m curious about your new house.
This could mean:
“I want to know more about your new house.”
You might want to know where it is, how large it is, how much it costs, or what it looks like.
“Curious” can also mean strange
There is another meaning of curious, although it is less important for this grammar question.
In some contexts, curious can mean strange, unusual, or unexpected.
For example:
- That is a curious thing to say.
- She noticed a curious mark on the wall.
Here, curious does not mean “wanting to know.” It means something like unusual.
However, when people say “I’m curious about…”, the meaning is almost always “I want to know more.”
Common learner confusion
A common mistake is to treat curious like a noun and choose a preposition without checking the normal English pattern.
Learners may say:
I am curious of your opinion.
The natural sentence is:
I am curious about your opinion.
The easiest thing to remember is that curious normally goes with about when you are talking about the thing you want to know more about.
5. What Does “About” Mean?
About is a very common English preposition. It has several meanings, but in curious about, it introduces the subject or thing that someone wants to know more about.
Consider this sentence:
I’m curious about your trip.
The word about connects curious with your trip. The speaker wants information about the trip.
Here are more examples:
- I’m curious about your new phone.
- She is curious about the results.
- He was curious about the strange sound.
- We are curious about your decision.
- Are you curious about the future?
- The students were curious about the experiment.
- My parents are curious about my new job.
- Everyone was curious about what happened.
“About” with nouns
The simplest pattern is:
curious about + noun
Examples:
- curious about school
- curious about the meeting
- curious about the result
- curious about your idea
- curious about the story
- curious about the problem
Sentence examples:
I’m curious about the meeting.
She is curious about your idea.
We are curious about the result.
“About” with pronouns
You can also use a pronoun:
- curious about him
- curious about her
- curious about them
- curious about it
- curious about you
For example:
I’m curious about him.
This means you want to know more about him.
She is curious about them.
This means she wants to know more about those people.
“About” with a question clause
This is one of the most useful patterns for learners.
You can say:
curious about + what/why/how/where/who
Examples:
I’m curious about what happened.
She’s curious about why you left.
He’s curious about how the system works.
They’re curious about where we are going.
I’m curious about who made this decision.
These sentences sound very natural in everyday English.
A useful point about “about”
Do not assume that about always means “approximately” or “concerning” in the same way.
For example:
The book is about animals.
Here, about means the subject of the book.
But:
I’m curious about animals.
Here, about introduces the thing that creates your interest.
The exact meaning depends on the words around it.
6. Difference Between “Curious Of” and “Curious About” (Detailed)
The most important point is simple:
Use “curious about” in normal modern English.
“Curious of” is generally not the natural choice when you mean that you want to know more about something.
Comparison table
| Expression | Common in modern English? | Meaning | Example |
|---|---|---|---|
| curious about | Yes | Wanting to know more | I’m curious about your plan. |
| curious of | Rare/unusual | Not normally used for this meaning | I’m curious of your plan. |
| curious to | Yes | Wanting to do/know something | I’m curious to see the result. |
| curious as to | Yes, but more formal | Wanting to know about something | We are curious as to why it happened. |
“Curious about” is the normal choice
When you have a topic, person, thing, situation, or fact that you want to know more about, use about.
Examples:
I’m curious about your new business.
She is curious about the answer.
He is curious about his neighbors.
We’re curious about what happened.
This is the structure you should learn first.
Why does “curious of” sound wrong?
English adjectives usually develop fixed patterns with particular prepositions. These combinations are sometimes called collocations.
For example:
- interested in
- afraid of
- good at
- proud of
- curious about
You cannot always choose a preposition simply because it seems logical.
A learner may think:
afraid of → curious of
But English does not work that way. Each adjective has its own usual pattern.
So:
I’m curious about the answer. ✅
Not:
I’m curious of the answer. ❌
Is “curious of” ever possible?
You may encounter curious of in older texts, literary language, dialectal use, or unusual constructions. It has appeared historically in English, but it is not the standard everyday expression most learners should use.
If your goal is natural modern English, especially for school, work, conversation, or general writing, choose “curious about.”
Compare these sentences
I’m curious about your brother.
Natural modern English.
I’m curious of your brother.
Unnatural to most modern speakers.
The difference is not really about the meaning of curious. The problem is the preposition that normally follows it.
7. Grammar Rules You Must Remember
Rule #1: Use “curious about” for a topic or thing
When you want information about a person, thing, event, idea, or subject, use:
curious about + noun
Examples:
I’m curious about the new teacher.
She’s curious about your project.
They are curious about the results.
Rule #2: Use “curious about” before a question clause
If the next part starts with what, why, how, where, or who, about is often the natural choice.
Examples:
I’m curious about what happened.
He is curious about why she left.
We’re curious about how it works.
She is curious about where they went.
Rule #3: Use “curious to + verb” for an action or experience
Another common structure is:
curious + to + base verb
Examples:
I’m curious to see the results.
She was curious to know what happened.
He is curious to find out more.
We’re curious to hear your opinion.
Notice the difference:
curious about + thing/topic
curious to + verb
Compare:
I’m curious about the results.
I’m curious to see the results.
Both are correct, but the grammar is different.
Rule #4: Do not use “curious of” as your normal pattern
For modern everyday English, avoid:
I’m curious of the answer.
Use:
I’m curious about the answer.
This simple change will make your English sound much more natural.
8. Common Mistakes Students Make
Mistake 1: “I am curious of…”
This is probably the biggest mistake related to this topic.
Wrong/unusual:
I’m curious of your opinion.
Better:
I’m curious about your opinion.
The reason is simple: curious commonly takes about when introducing the thing someone wants to know more about.
Mistake 2: Forgetting the preposition
Some learners say:
I’m curious your new job.
This is not correct.
Use:
I’m curious about your new job.
Mistake 3: Confusing “curious about” and “curious to”
Both can be correct, but they have different structures.
Compare:
I’m curious about the new restaurant.
Here, the new restaurant is the topic.
I’m curious to try the new restaurant.
Here, to try describes an action the speaker wants to experience.
Mistake 4: Using “curious about” with the wrong verb form
You may hear learners say:
I’m curious about know the answer.
That is incorrect.
After about, use a noun, pronoun, or suitable clause. If you want to use know, use the to structure:
I’m curious to know the answer.
Or use a question clause:
I’m curious about what the answer is.
Easy correction tip
When you see curious, ask yourself:
“Am I talking about a thing/topic?”
If yes:
curious about + noun/topic
If you want to describe an action:
curious to + verb
This quick question can prevent many mistakes.
9. Easy Trick to Remember the Difference
Here is a very easy memory trick:
Curious ABOUT = curious about a topic
Think of about as pointing to the subject of your curiosity.
curious about the movie
Curious of or Curious About
Curious of or Curious About
Curious of or Curious About
You can imagine yourself saying:
“I want to know more about it.”
That is the key idea.
Another simple trick
Remember this pair:
Interested in
Curious about
For example:
Curious of or Curious About
Curious of or Curious About
Both sentences are natural, but the prepositions are different.
Do not copy the preposition from another adjective.
English learners often know:
Curious of or Curious About
Curious of or Curious About
Curious of or Curious About
and then try to guess the preposition after curious. Instead, memorize the useful phrase as one unit:
curious about
That is much easier.
