优

• Pinyin: yōu
• Hanzi breakdown: 优 = 人 + 忧 simplified (person + anxiety — originally a ritual performer; evolved to mean excellent)

Meaning

Excellent; superior; of outstanding quality. Used in formal evaluation systems to denote the highest grade, and as a productive prefix in compounds expressing superiority.

Functions both as a standalone evaluative term (成绩评为优 — results rated excellent) and as a productive morpheme in compounds: 优质 (high-quality), 优先 (priority), 优待 (preferential treatment), 优胜 (superior, winning). In grading systems, the scale typically runs 优 → 良 → 中 → 差. Also used in literary contexts to mean graceful or accomplished.

Examples

1. 这所百年名校将学术、实践和创新纳入统一评价，用优良中差四级制取代百分制，推动全面发展。 This century-old elite school has put academics, practice, and innovation into one evaluation system, replacing percentage scores with a four-level scale of excellent, good, average, and poor to promote all-round development.
2. 这批精密仪器测试后被评为优，性能全面达标。 After testing, this batch of precision instruments was rated excellent and met all performance standards.
3. 在表演艺术品评中，优既指技艺精湛，也指人格高洁。 In evaluating performing arts, excellence refers both to superb skill and to noble character.
