n. the quality of being full of energy, excitement, and cheerfulness
n. (of vegetation) the state of growing luxuriantly or abundantly
The word "exuberance" traces back to Latin exuberantia, derived from exuberare ("to be abundant"). The prefix ex- ("out") intensifies the root uber ("abundant, fertile"), originally referring to fertile soil or overflowing milk (from uber, "udder"). Over time, it evolved metaphorically to describe overflowing energy or vitality in both nature and human behavior. The suffix -ance nominalizes the quality.
