急性

急性 (jí xìng) is an adjective meaning 'acute' in English, typically used to describe conditions that are severe, sudden, or intense, especially in medical contexts. It contrasts with 'chronic,' which refers to long-term or persistent conditions.

The character 急 (jí) means 'urgent' or 'immediate,' while 性 (xìng) is a suffix indicating 'nature' or 'character.' Together, they form a term that describes something with a sharp, sudden onset.

In everyday usage, 急性 is most commonly found in medical terminology, such as 急性病 (jí xìng bìng), meaning 'acute illness.' Understanding this term is essential for anyone studying health-related Chinese or interacting with medical information in Chinese.
