If you are unsure if to say “curious of” or “curious about,” you are not alone. These expressions look similar, but they are not equally natural in modern English. In most everyday situations, “curious about” is the correct and natural choice when you want to say that you want to know more about something.
The adjective curious commonly means interested in learning or knowing something. It is normally followed by about when the object is a person, thing, subject, event, or situation. For example, you can say, “I’m curious about your new job” or “She is curious about what happened.” Understanding this small preposition difference can make your English sound much more natural and confident.
Quick Answer
“Curious about” is the standard and natural expression in modern English. Use it when you want to express interest in learning or knowing more about someone or something. “Curious of” is generally not used in ordinary modern English for this meaning. Instead, use “curious about,” “curious to know,” or “curious to see.”
Why People Confuse It
People often confuse curious of and curious about because English adjectives can take different prepositions, and there is no simple rule that tells learners which preposition belongs with every adjective.
For example:
- interested in something
- worried about something
- afraid of something
- curious about something
Because of is common after many adjectives, learners may naturally wonder whether curious of is also correct.
Another reason for the confusion is that curious and curiosity are related to the idea of wanting to know something. However, the usual modern construction is curious about, not curious of.
For example:
- I’m curious about your decision.
- She was curious about the strange noise.
- We’re curious about what happened.
Curious About
Curious about means interested in finding out more about a person, thing, subject, event, or situation.
It is the normal expression in contemporary English.
Examples

- She is curious about the results.
- They were curious about what happened.
- Are you curious about his decision?
