Ludwig's WRAP-UP
In summary, while the phrase "looked interested" is commonly used to describe someone's apparent interest or attentiveness, Ludwig AI points out that it is not considered correct in standard written English. Adding a preposition like "in" clarifies the subject of interest, making it grammatically stronger. While frequently found in News & Media, being neutral in register, it's better to use alternatives like "seemed intrigued" or "appeared attentive" for clearer communication. The key takeaway is to always specify the object of interest for grammatical correctness.
