Adjectives for Curious People: Inquisitive, Nosy and Everything Between
To describe a curious person, the most useful adjectives are inquisitive and inquiring (in a good way), interested, intrigued, eager and wide-eyed (milder or more innocent), and nosy, prying and snooping when the curiosity is about other people’s private business. Be careful with curious itself: it has two meanings, “wanting to know” (a curious child) and “strange” (a curious smell), and sometimes a sentence could mean either.
This page sorts the words by how positive or negative they sound, then covers words for curious looks and questions, the “strange” sense of curious, the mistakes learners make most, and a short practice set with answers. For words about character in general, see adjectives for personality.
The two meanings of “curious”
| Meaning | Examples | Similar words |
|---|---|---|
| 1. wanting to know or learn | “Toddlers are curious about everything.” “I’m curious to see how the film ends.” | inquisitive, interested, eager to know |
| 2. strange, unusual, hard to explain | “There was a curious smell in the basement.” “It’s curious that nobody heard the alarm.” | odd, peculiar, strange, puzzling |
Sense 2 is common in careful writing: “a curious mixture of pride and shame”, “curiously quiet”, “the curious incident of the dog in the night-time” (a line from a Sherlock Holmes story, later used as the title of Mark Haddon’s novel). In Lewis Carroll’s Alice’s Adventures in Wonderland, Alice’s “Curiouser and curiouser!” means “stranger and stranger”, and the book notes she had forgotten how to speak good English, so the form is a joke, not a model.
The two senses can collide when you describe a person. “He’s a curious man” could mean he asks a lot of questions or that he is odd. If the context does not make it clear, choose inquisitive for the first meaning and odd or peculiar for the second.

Good curiosity: the eager learner
- inquisitive: always asking questions and wanting to find things out. “Our inquisitive four-year-old wants to know why the moon follows the car.” For adults it is usually a compliment (“an inquisitive scientist”) but can lean toward nosy if the questions are personal: “an inquisitive landlady”.
- inquiring: mostly in an inquiring mind and an inquiring look. “She has a sharp, inquiring mind.” British writers also spell it enquiring.
- curious (sense 1): the everyday word. “Cats are curious animals.” “I was curious about how the trick worked.”
- intellectually curious: common in job ads and school reports for someone who wants to understand ideas. “We are looking for intellectually curious graduates.”
- eager to learn: about motivation more than questions. “The new apprentice is eager to learn and never minds being corrected.”
- open-minded: curious about views unlike your own. “She is open-minded enough to read papers she disagrees with.”
In a reference letter or a self-description, inquisitive and intellectually curious are the strongest choices. “Curious” alone is fine but slightly plain.
Interested, intrigued, fascinated: curiosity about one thing
These describe a reaction to something specific rather than a personality trait, and each takes its own preposition.
- interested in: “He’s interested in old maps.”
- intrigued by: interested because something is unusual or mysterious. “I was intrigued by the locked drawer in the desk.”
- fascinated by: very strongly interested, unable to look away. “The children were fascinated by the octopus.”
- keen on (mostly British): “She’s keen on astronomy.”
- rapt: so absorbed you forget everything else. “The class listened in rapt silence.”
- agog (informal, a little old-fashioned): eager and excited to hear more. “The whole office was agog at the news.”
Curious looks, questions and behavior
Often you are not describing the person at all but their face, eyes or questions.
- a curious glance: “The other passengers gave the man with the parrot curious glances.”
- a quizzical look: puzzled and questioning, often slightly amused. “She raised an eyebrow and gave me a quizzical look.” (More Q-words are in adjectives that start with Q.)
- a searching look: a look that tries to read your thoughts. “Her mother gave her a long, searching look.”
- wide-eyed: eyes wide with wonder or surprise. “Wide-eyed tourists filled the square.”
- probing questions: questions that dig for the truth; neutral or positive in an interview, hostile in an argument. “The journalist’s probing questions exposed the gap in his story.”
- questioning: “He gave a questioning frown, as if he didn’t believe me.” A questioning attitude is one that doesn’t accept things without proof.
Investigative belongs here only for work: investigative journalism, an investigative reporter, an investigative committee. You would not call a person “investigative” in everyday speech; say inquisitive.
Too curious: nosy, prying and the rest
These words criticize someone for wanting to know what is none of their business. They differ in how far the person goes.
| Word | What the person does | Example |
|---|---|---|
| nosy (also nosey) | wants to know other people’s private affairs | “Our nosy neighbor knows who visits us before we do.” |
| prying | actively tries to find out secrets | “Keep the diary away from prying eyes.” |
| snooping | looks secretly through things or places | “I caught him snooping around my desk.” |
| intrusive | asks or does things that invade privacy | “The questions about her divorce were intrusive.” |
| meddlesome / interfering | gets involved and tries to control | “Her interfering aunt rearranged the wedding seating.” |
| gossipy | enjoys talking about others’ private lives | “a gossipy office” |
Two informal nouns go with these: a busybody (anyone who interferes) and, in British English, a nosy parker. “Don’t be such a nosy parker” is teasing rather than angry.
The difference between inquisitive and nosy is about whose business it is. Asking how a bridge holds up is inquisitive; asking a colleague how much they earn is nosy.
Common mistakes
| Instead of… | Write… | Why |
|---|---|---|
| I’m curious of the result. | I’m curious about the result. / I’m curious to know the result. | Modern English uses curious about or curious to + verb. |
| She is very investigative. | She is very inquisitive. | Investigative describes professional work, not a personality. |
| He was searching about the old map. | He was intrigued by the old map. | Searching as an adjective means “trying to read someone” (a searching look). |
| an intriguing student (meaning “curious”) | an intrigued student | Intriguing = causing curiosity; intrigued = feeling it. |
| Thank you for being so nosy about my project! | Thank you for being so interested in my project! | Nosy is always a criticism, even when joking. |
| a curious smell (when you mean you want to smell it) | an intriguing smell | “A curious smell” means a strange smell. |
| more curiouser | more curious | “Curiouser” exists only as Lewis Carroll’s joke. |
Sayings about curiosity
- Curiosity killed the cat: a warning not to ask too many questions. Some people add “…but satisfaction brought it back”, a later jokey reply that turns the warning around.
- Inquiring minds want to know: said jokingly when you ask for gossip or details.
- Just curious / I’m only asking out of curiosity: a softener that tells the listener you have no hidden purpose.
- Idle curiosity: curiosity with no serious reason. “Out of idle curiosity, how old is this building?”
A model paragraph
“My grandfather was the most inquisitive man I have ever known. At eighty he would still stop a stranger to ask about the dog breed, the tattoo, the strange instrument in the case. He was never nosy, though; he asked about things, not about money or marriages. My grandmother, who found his questions tiring, used to give him a quizzical look across the table that meant ‘Again?’ And there was a curious side to him as well, in the other sense: he kept every bus ticket he ever bought, sorted by year, in shoeboxes nobody was allowed to open.”
The paragraph uses inquisitive for the positive trait, nosy to rule out the negative one, quizzical for a look, and curious deliberately in the “strange” sense, signalled by “in the other sense”.
