The Confusion Around “Interested In” vs. “Interested On”
English learners often struggle with prepositions, and one common mistake is using “interested on” instead of “interested in.” While both prepositions are used in various contexts, only “interested in” is correct when expressing curiosity, passion, or engagement with something. The phrase “interested in” naturally fits when discussing hobbies, topics, or activities, such as “I am interested in music” or “She is interested in learning new languages.” On the other hand, “interested on” is incorrect and not used in standard English.
The confusion arises because different languages have varying prepositional rules, and direct translations can lead to errors.
Many English learners struggle with preposition in usage, especially when it comes to expressions like “interested in.” It’s easy to assume that “on” could be correct because we say, “focus on” or “keen on.” However, “interested on” is incorrect.
Why Do People Make This Mistake?
- Influence from other languages: In some languages, “on” and “in” are interchangeable.
- Prepositional confusion: English prepositions don’t always follow a set logic.
- Lack of exposure: Learners may not hear native speakers use “interested in” often enough.
The goal of this article is to provide a clear, easy-to-understand explanation of why “interested in” is correct and why “interested on” should be avoided.
The Short Answer: “Interested In” vs. “Interested On”
Which One Is Correct?
The correct phrase is “interested in.” When expressing curiosity, passion, or involvement with something, English speakers always use “interested in” followed by a noun or verb in the -ing form. For example, “She is interested in photography” or “They are interested in learning new skills.” This phrase correctly conveys enthusiasm or concern about a topic.
On the other hand, “interested on” is incorrect and not used in standard English. Some learners mistakenly use it due to the influence of other languages or confusion with similar phrases like “on TV” or “on a topic.” However, in English, “interested” always pairs with “in” when describing personal engagement.
To speak and write correctly, always remember that “interested in” is the right choice. Mastering this small but important detail will help you sound more fluent and natural in English conversations and writing.

For example, “He is interested in science” means that he enjoys learning about science. Similarly, “She is interested in playing the piano” shows that she enjoys or wants to learn how to play.
In English, “interested” is always followed by “in” when talking about passions, hobbies, or areas of focus. The structure is usually “interested in” + noun or verb (-ing form)—for example, “They are interested in traveling” or “I am interested in history.” This phrase helps describe what excites or attracts someone’s attention.
Understanding “interested in” and using it correctly makes English communication clearer and more natural. Mastering this simple rule will help you avoid mistakes and improve your fluency.
According to English language experts, “interested in” means having curiosity, enthusiasm, or attraction toward something. It expresses that a person finds a subject, activity, or idea engaging.
Grammatical Explanation
“Interested” is an adjective, and the correct preposition that follows is always “in.” This is because “in” indicates involvement or curiosity.
Examples of “Interested In”
- Personal interests: “I’m interested in art and painting.”
- Education & Learning: “She is interested in learning new languages.”
- Career choices: “He’s interested in finance and investment banking.”
- Hobbies & Activities: “They are interested in gardening and landscaping.”
Tip: If you’re ever unsure, think about the phrase “have an interest in.” Since we say, “I have an interest in photography,” we also say, “I’m interested in photography.”
Why “Interested On” is Incorrect
The phrase “interested on” is grammatically incorrect in English. Many learners mistakenly use it because “on” is a common preposition in other contexts, such as “on TV” or “on a topic.” However, when expressing curiosity or enthusiasm, “interested” must always be followed by “in,” not “on.”
For example, saying “I am interested on science” is incorrect, while “I am interested in science” is the right way to express curiosity about the subject. Avoiding this mistake will make your English sound more natural and fluent. Always use “interested in” for proper grammar and clear communication.
Although “on” is a common preposition in English, it does not work with “interested.”
Why Do People Say “Interested On”?
- Language interference: Some languages use “on” instead of “in” for similar expressions.
- Confusion with other phrases: We say “focus on” or “keen on,” but “interested in.”
If you ever find yourself saying “interested on,” pause and switch it to “interested in.”
