The word "踊跃" is formed by combining the characters 踊 and 跃, both meaning "to jump". 踊 includes the foot radical ⻊ and the phonetic component 甬, indicating a leaping action. 跃 also contains the foot radical ⻊ with the component 夭, which serves a phonetic role and relates to movement. Together, they create a compound where the shared meaning of jumping is reinforced, leading to the modern metaphorical sense of acting eagerly or enthusiastically.
