‘飞跃’ literally combines ‘飞’ (to fly) and ‘跃’ (to leap or jump), evoking a powerful, dynamic motion—like a bird soaring upward in one bold, sweeping movement. As a noun, it signifies a sudden, dramatic advance or breakthrough, often implying qualitative progress rather than gradual improvement. It’s commonly used in formal or inspirational contexts: technological innovation, economic development, personal growth, or scientific discovery.

The word carries positive, aspirational connotations and is frequently found in official reports, news headlines, and motivational speeches. While it can describe physical leaping (e.g., an animal’s agile movement), its dominant modern usage is metaphorical—emphasizing transformative change that feels almost miraculous in scale and speed. Unlike ‘进步’ (progress), which suggests steady advancement, ‘飞跃’ implies a discontinuous, quantum-like shift—hence the English equivalents ‘quantum jump’ or ‘great leap’.
