The word 跳跃 is formed by combining two characters, 跳 and 跃, which both individually mean "to jump" or "to leap". This is a common method in Chinese for creating a compound word where two near-synonyms are paired together. Their combination does not create a new meaning but rather reinforces and enriches the core concept, resulting in a single, cohesive term that evokes a stronger, more vivid sense of dynamic, springing motion than either character might alone.
