Usage: Use enthusiastic to describe someone who shows eager and passionate interest in an activity or idea. This word often replaces more neutral terms like interested when you want to emphasize high energy and motivation.
The word enthusiastic comes from the Ancient Greek enthusiastikos, where it originally described a state of being inspired by a god. It entered English with this same core meaning, referring to someone filled with intense excitement or passion.
