In

CHIC

It’s a stylish term for something fashionable that also means "within" in French.

The word "in" here is a hint to look for a synonym that also means stylish or fashionable. "Chic" fits because it sounds like "sheek" (a playful take on "chic") when said aloud, and it’s a common term for something trendy or elegant. Think of it as a double meaning—"in" as in popular, and "chic" as the word that matches that idea.
