渴望 is a verb meaning 'to yearn for' or 'to long for' something deeply and emotionally — often something desired but not yet attained. The character 渴 (kě) literally means 'thirst', evoking physical urgency, while 望 (wàng) means 'to look toward' or 'to hope for', suggesting aspiration and direction. Together, they form a vivid metaphor: just as thirst drives one to seek water, 渴望 conveys an intense, almost visceral emotional drive toward a goal, person, experience, or ideal.

This word is commonly used in both spoken and written Chinese, especially in formal, literary, or reflective contexts — such as expressing deep personal desires (e.g., for knowledge, freedom, love, or success), or describing collective aspirations (e.g., social change or environmental protection). It carries a tone of sincerity and earnestness, and is stronger than general words like 想要 (to want) or 希望 (to hope).
