When learning English, many learners wonder about small phrases, especially “Curious Of” or “Curious About”, which differ subtly but matter. Curiosity drives understanding, and noticing tiny details can prevent confusion and make your English conversations smooth, whether traveling, meeting new people, or sharing ideas.
Curious about is usually the correct choice when exploring a topic, place, person, or idea. For instance, saying “I’m curious about the local food here” shows your interest clearly and helps conversations flow. On the contrary, curiosity is less common and may sound awkward to native speakers, even if the rules appear flexible.
Paying attention to such small differences improves clarity and communication. Each word or phrase we choose carefully adds to learning and connecting naturally with others. Over time, these adjustments help your English sound more natural and make interactions with people smoother and easier.
Understanding “Curious About”: Meaning and Grammar
When you say someone is “curious about” something, you are describing their interest or desire to know more. It’s an adjective + preposition + object structure, which is very common in English.
Examples of correct usage:
- I’m curious about your new project.
- She was curious about the strange noise outside.
- They’re curious about how the new software works.
In every case, “about” connects the adjective curious with the object of interest. This is the standard and widely accepted form in both written and spoken English.
The rule is simple: use “about” when expressing curiosity regarding a person, object, event, or idea.
The Problem with “Curious Of”: Why It Feels Wrong
Many learners-and even some native speakers-use “curious of” out of habit or misunderstanding. The phrase may have appeared in older texts, but in modern English, it is considered incorrect.
Incorrect examples:
- I’m curious of your opinion. ❌
- She was curious of the new policy. ❌
These sentences feel awkward because “of” does not properly link the adjective to the object in contemporary English. It can confuse readers or listeners, making your writing sound less fluent.
A helpful tip: If “of” sounds unusual in your sentence, replace it with “about.” In almost every case, this will fix the issue.
When “Curious Of” Appears: Informal Speech, Literature, and Dialects
Though “curious of” is largely outdated, it can still appear in literary texts, historical documents, or regional dialects. For example, in 18th-century literature, you might find phrases like:
- He was curious of the new invention.
In these cases, “of” functioned as the preposition linking curiosity to the object, but language usage has evolved. Today, this construction is rarely used in formal writing or spoken English.
Summary: Avoid “curious of” in professional or academic contexts. Reserve it for historical quotes or stylistic choices when referencing older texts.
The Role of Prepositions in English
Prepositions are small but powerful words. They change meaning and show relationships between words. Choosing the wrong preposition can make even a simple sentence incorrect.
Common adjectives and their prepositions:
| Adjective | Correct Preposition | Example |
| Interested | in | She is interested in photography. |
| Excited | about | He is excited about the concert. |
| Curious | about | They are curious about the results. |
| Afraid | of | I’m afraid of spiders. |
| Responsible | for | She is responsible for the project. |
Notice the pattern: “curious” aligns naturally with “about,” just like “excited about” or “interested in.”
Historical Perspective: How “Curious Of” and “Curious About” Evolved
Historically, “curious of” was more common in English between the 16th and 18th centuries. Authors like Samuel Johnson and Jane Austen occasionally used it.
For example, a sentence from older texts might read:
- He was curious of her intentions.
Over time, English shifted toward “curious about,” which became standard in the 19th and 20th centuries. Today, dictionaries such as Merriam-Webster and Oxford clearly list “curious about” as the correct form.
This evolution reflects English’s tendency to favor clarity and precision in prepositional usage.
Correct Usage of “Curious About” in Everyday Context
Using “curious about” correctly is straightforward once you understand the context. Here are some practical scenarios:
Professional or Academic Contexts:
- I’m curious about the new research findings.

Casual Conversations:
- I’m curious about your weekend plans.

Travel or Exploration Context:

FAQs
Is “curious of” ever correct in English?
“Curious of” is considered archaic and is rarely used in modern English. It appears occasionally in historical or literary texts, where older grammatical conventions applied. In contemporary usage, it’s almost always incorrect, especially in professional, academic, or casual contexts. Using “curious about” is the standard, widely accepted form. While you may encounter “curious of” in quotes or classical literature, applying it in everyday communication will sound awkward. To be safe, always replace “curious of” with “curious about,” ensuring clarity, natural tone, and grammatical accuracy in your writing and speech.
Can I use “curious about” in formal writing?
Absolutely. “Curious about” is versatile and works in both formal and informal contexts. In essays, reports, or professional emails, it clearly conveys interest or inquiry. For instance, “I am curious about the latest research findings” is appropriate in academic papers, whereas “I’m curious about your weekend plans” fits casual conversations. Its neutral tone makes it suitable for virtually any situation, ensuring that your communication remains polished and professional while expressing genuine curiosity. It is the preferred choice over outdated alternatives like “curious of.”
What are some alternatives to “curious about”?
Several alternatives can replace “curious about” depending on context. Common options include “interested in,” “intrigued by,” “fascinated with,” and “wondering about.” “Interested in” suits general or professional contexts, “intrigued by” implies intellectual engagement, “fascinated with” suggests strong admiration, and “wondering about” is casual and conversational. Choosing the right alternative helps diversify your writing, avoid repetition, and maintain precise expression. Always consider the audience, tone, and level of formality when selecting a substitute for “curious about.”
How can I remember to use “about” instead of “of”?
Think of curiosity as reaching toward knowledge or information. The preposition “about” naturally indicates direction or focus, linking the adjective to its object. In contrast, “of” doesn’t convey this relationship clearly. A practical tip is to ask yourself: “Am I expressing interest or inquiry about something?” If yes, use “about.” Reading and listening to native English examples also reinforces correct usage. Over time, it becomes instinctive to pair curious with about in everyday conversation, writing, and professional communication, eliminating confusion entirely.
Are there common mistakes with similar adjectives?
Yes. Many adjectives confuse learners because prepositions vary. For example, people often say “interested about” or “excited of,” which are incorrect. Correct forms include “interested in” and “excited about.” Like “curious about,” these pairings follow specific adjective + preposition patterns. Mistakes usually occur because learners generalize rules across adjectives. Paying attention to collocations-words that naturally go together-solves this problem. Reading widely, using reliable dictionaries, and practicing sentences helps internalize the correct patterns, making your English precise and fluent.
