Which word describes someone who is full of excitement and eager?

The term "agog" perfectly captures the essence of someone who is filled with excitement and eagerness. It conveys a sense of being intensely curious and enthusiastic about something, suggesting that a person is eagerly awaiting an event or outcome. This word reflects a heightened emotional state where the individual is not only interested but also excited and full of anticipation, making it an ideal descriptor for such sentiments.

In contrast, "alleviated" denotes a sense of relief or reduction, typically in a context where discomfort or distress has been lessened, which does not align with excitement. "Aged" refers to the state of being old or having lived for a long time, which is unrelated to excitement or eagerness. Lastly, "apathetic" describes a lack of interest or enthusiasm, which is the opposite of being excited. Therefore, "agog" stands out as the most fitting choice to describe someone who is enthusiastic and eager.
