先天

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

含义

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.

正确说法

• 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.)

错误说法

• 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

起源与历史

先 (before, prior) + 天 (heaven, nature — representing the natural order before human intervention)
