先天

• Pinyin: xiān tiān
• Hanzi breakdown: 先 = 丿+ 土 + 儿 (one who goes ahead — prior); 天 = 一 + 大 (heaven, the great above — nature)

Meaning

Innate; congenital; inborn. Refers to qualities, conditions, or characteristics that exist from birth, prior to any acquired learning or environmental influence.

Used in both medical and non-medical contexts. In medicine: congenital defects, hereditary conditions (先天性心脏病 = congenital heart disease). In general usage: natural talent, innate disadvantages, or structural conditions that predate a system or situation. Contrasts with 后天 (acquired, postnatal). Common in philosophy, genetics, and educational discourse.

Examples

1. 她在音乐方面展现出的惊人天赋令人难以置信，很多专业老师都认为这种能力有一定的先天因素。 Her extraordinary musical talent is hard to believe, and many professionals think it’s partly due to innate factors.
2. 这名运动员先天的身体条件极为出色，再加上多年如一日的刻苦训练，才成就了今日的辉煌成绩。 This athlete’s natural physical attributes are outstanding, and together with years of relentless training, they produced today’s remarkable achievements.
3. 该制度设计存在先天性的制衡缺陷，使得权力监督机制在实践中难以有效发挥应有作用。 The design of this system has an inherent checks-and-balances flaw, making effective oversight difficult to achieve in practice.

Do Say

• 儿科遗传学研究表明，许多发育障碍可追溯到基因层面的先天变异，而不只是后天环境因素，这正改变早期干预策略。(Pediatric genetics research shows that many developmental disorders can be traced to congenital genetic variations rather than just environmental factors, and this is changing early intervention strategies.)
• 讨论教育公平时，学界承认先天能力差异客观存在，但也强调高质量后天教育能弥补不足、促进流动，不能因此放弃机会均等。(In discussing educational equity, scholars acknowledge that innate ability differences objectively exist, but they also stress that high-quality education can compensate for weaknesses and promote mobility, so equal opportunity cannot be abandoned because of these differences.)

Don't Say

• 先天 as a synonym for 'natural' in general usage when describing acquired or learned attributes — 先天 specifically denotes what is present from birth, before any experience or learning
