Obsessed with

INTO

Think of a casual way to say you're really enthusiastic about something, like a hobby or trend—it’s just two letters longer than "in.

Obsessed with" is clued as "INTO" because the word has evolved in casual speech to mean deeply interested or enthusiastic about something. While "into" literally means moving inside, it’s also slang for being passionate or fixated—like saying someone is "really into music." The clue plays on this modern usage rather than the word’s original definition. It’s a straightforward example of how everyday language shapes crossword answers.
