When someone is trying to convey their enthusiasm about something, they might use a variety of synonyms for "explain excitedly." They might describe their feelings of excitement as "gushing" or "giddy," or they might say they're "bursting with enthusiasm" or "bubbling over" with excitement. Other synonyms could include "rhapsodizing," "effusing," "radiating," or "enthusing." No matter which synonym they choose, the goal is the same: to convey their passionate and joyful feelings about the subject at hand. Whether they're describing a new hobby, a book they've read, or an upcoming trip, an enthusiastic explanation can help to spread positivity and excitement to those around them.
