长 🔊

网络内容摘要 (Web Content Summary):

核心含义与象形起源：“长”最基本的含义是“长度长”或“延伸”。最早的“长”字是合体象形字，下方像一个人，上方表示长发，整体象征“头发很长”，引申为“长久”或“生长”的意思。 Core meaning & pictographic origin: The primary meaning of “长” (cháng) is “long” or “length.” The earliest form is pictographic: the lower part resembles a person, the upper part represents long hair, thus indicating "having long hair" and extending to mean "long" or "to grow."

• 常见用法：“长”可作形容词/名词，表示“长度长”；也可作动词，表示“生长”或“变长”。 Common usage: As an adjective/noun, “长” means “long” or “length;” as a verb, it means “to grow” or “become longer.”
• 易混用点：汉字“长”还有另一个发音“zhǎng”，常用于“校长（principal）”、“部长（director）”等，表示“leader”或“to grow up”。但在表示“长度”时，读作“cháng”。 Note on confusion: “长” has another pronunciation “zhǎng,” used for meanings like “leader” (as in principal, director) or “to grow up.” For “length/long,” it's pronounced “cháng.”
• 常用词和成语举例：“长衣”（long robe）、“长城”（The Great Wall）、“长久”（long-lasting）。成语如“日久天长”（as time passes by）。 Examples: “长衣” (long robe), “长城” (The Great Wall), “长久” (long-lasting). Idiom: “日久天长” (as time passes by).
• 历史用例：《论语》中“长一身有半”（长度为身体的一倍半）；《汉书》“长数十丈”（极长的流星）。 Historical examples: In Analects: “长一身有半” (blanket’s length is 1.5 times a person’s height); in Book of Han: “长数十丈” (a meteor was tens of zhàng long).
