* Curious: This is the most common translation, meaning "inquisitive, eager to learn or know more."
* Strange: In some contexts, it can also mean "unusual, odd, or peculiar."
The specific translation depends on the context. For example, "Il est curieux de voir ce qu'il va faire" (He is curious to see what he will do) translates to "He is curious to see what he will do."
