‘认真’ is an adjective meaning ‘serious,’ ‘earnest,’ or ‘careful’ — describing someone’s attitude or approach to a task. The character 认 (rèn) means ‘to recognize’ or ‘to acknowledge,’ and 真 (zhēn) means ‘true’ or ‘genuine.’ Together, they convey the idea of approaching something with sincerity and full attention — as if truly recognizing its importance and acting accordingly. It emphasizes authenticity of effort rather than just intensity.

This word is commonly used in school, work, and daily life contexts: students study 认真, employees work 认真, and people listen 认真 during conversations. It often appears after subject + verb (e.g., 他学习很认真) or before verbs in adverbial phrases (e.g., 认真听讲). Unlike English ‘serious,’ it rarely carries negative connotations like ‘stiff’ or ‘grim’ — instead, it’s consistently positive and commendatory.
