'成就' (chéng jiù) is a noun meaning 'achievement' or 'accomplishment' — something successfully completed or attained through effort, skill, or perseverance. The character 成 (chéng) means 'to succeed' or 'to complete', while 就 (jiù) reinforces the sense of 'attaining' or 'reaching' a goal; together, they emphasize the result of dedicated action. It often carries a positive, respectful connotation and is commonly used to describe academic, professional, artistic, or personal milestones.

This word appears frequently in formal and semi-formal contexts — such as speeches, news reports, biographies, or performance reviews — rather than casual daily speech. While it can refer to major life accomplishments (e.g., winning an award), it may also describe modest but meaningful goals (e.g., learning a language). Unlike the more colloquial '成绩' (chénɡ jì), which often refers specifically to academic or measurable results, '成就' implies broader significance and lasting value.
