Understanding ‘Interested In’ and Common Mistakes with Other Prepositions 間違いやすい興味がある＋前置詞2025.02.09

Have you ever wondered whether to say “interested in,” “interested on,” “interested about,” or “interested at”? You’re not alone! English learners and even native speakers sometimes get confused about which preposition to use. Let’s clear things up in a fun and friendly way!

The Correct Usage: Interested In

The most natural and grammatically correct phrase is “interested in.” This phrase is used when talking about topics, hobbies, activities, or people that capture your curiosity or enthusiasm.

✅ I am interested in learning new languages.✅ She is interested in photography.✅ They are interested in science fiction movies.

When in doubt, stick with “interested in.” It’s the standard phrase and always sounds right!

Common Mistakes and Why They Don’t Work

Now, let’s take a look at some incorrect variations and why they don’t fit in standard English.

❌ Interested on – While it may seem logical, we don’t say “interested on” because “on” typically refers to physical surfaces or locations.➡️ Incorrect: He is interested on technology.➡️ Correct: He is interested in technology.

❌ Interested about – “About” is used when talking about general topics, but not in this context.➡️ Incorrect: I am interested about history.➡️ Correct: I am interested in history.

❌ Interested at – “At” is used for locations or specific points in time, so it doesn’t work with “interested.”➡️ Incorrect: She is interested at painting.➡️ Correct: She is interested in painting.

Final Thoughts

If you ever get confused, just remember: “interested in” is always correct! Avoid “interested on,” “interested about,” and “interested at,” as they don’t fit naturally in English.
