An enthusiastic person shows lots of excitement and energy about something.
When we describe someone as enthusiastic, we usually mean that they love or really enjoy doing something. For example, if your friend starts talking about their new favorite TV show and can't stop smiling, you might say they're being really enthusiastic about it. This means they have a lot of passion and eagerness to share their thoughts and feelings with others.
With zealous fervor; excited, motivated.
Example: an enthusiastic lover of art
