兆 🔊

网络内容摘要 (Web Content Summary):

核心含义与象形起源：“兆”字最早见于甲骨文，最初的字形像两个人背对背站着，并以“水”为背景。古人解释为“两人背水而逃”，表示“逃”的意思，即逃跑、躲避。后来在金文中，人形逐渐演变为“止”形，更突出“逃跑”的意义。Core Meaning & Origin: The character “兆” first appeared in oracle bone script, depicting two people back-to-back with water between them—originally meaning “to flee” or “run away.” In later bronze scripts, the human figures changed into the “止” shape, emphasizing the notion of escaping.

特殊用法与易混淆点：古时，“兆”字和“𠔁”字（龟甲卜辞中的兆纹）易混淆。现在，“兆”有“预兆、征兆”之意，常指事情发生前的迹象。此外，“兆”在现代也用作数量词（如“一兆=一千万、一万亿”视国家标准而定），需注意和“兆（预兆）”区分。Special Usage & Confusion: In ancient scripts, “兆” could easily be confused with the character “𠔁” used for cracks in turtle-shell divination. Today, “兆” commonly means “omen” or “sign” (as in a premonition). It also serves as a large numerical unit (trillion, or 10^12/10^6/10^4 depending on region), so care is needed not to mix the senses.

• 常用词：征兆（omen, sign），预兆（premonition, portent） Common Words: 征兆 (zhēngzhào: omen, sign), 预兆 (yùzhào: premonition, portent)
• 成语：无征不信，无兆不验（Nothing is credible without evidence, nothing is valid without signs） Idioms: 无征不信，无兆不验 (Things need evidence and signs to be believed or confirmed)

注意：由于古籍记载不同，关于“兆”字最早出现和本义还有争议，但现代常用义为“预兆、迹象”。Note: Owing to differences in ancient records, the earliest meaning of “兆” is still debated, but its modern sense as “omen” or “sign” prevails.
