九 🔊

网络内容摘要 (Web Content Summary):

九（读作 jiǔ）是汉语常用数字字，最早见于甲骨文。 Jiǔ is a commonly used Chinese character representing the number nine, first appearing in Oracle Bone Script.

• 核心含义：“九”最基本的意思是数字“9”。 Core meaning: “九” fundamentally means the number nine.
• 象形起源：字形模拟事物屈曲、变化至终结的样子，被认为有“曲折究尽”之意。 Pictographic origin: The shape of the character represents something bent or twisted to its end, symbolizing completion or finality.
• 文化背景：古代常把九看作最大的阳数，因此常用“九”象征多数、极致或长久。例如中国成语“九九归一”。此外，冬至起每九天称一“九”，常用来计算冬天的时令（如“数九寒天”）。 Cultural background: In traditional Chinese culture, nine is seen as the largest odd (yang) number and often symbolizes abundance, extremity, or longevity. For example, the winter period is divided into segments of nine days each (“nine nines” to mark the coldest time).
• 其他用法与易混点：“九”本义曾表示“伸手探究”，后来“究”字取而代之。与“久”同音，但意义不同，书写需区分。 Other uses and common confusions: Historically, “九” also meant “to search or probe with the hand,” but this meaning is now expressed by the character “究.” “九” (nine) is pronounced the same as “久” (long time), but has different meanings and writings.
• 常见词语和成语：如“九九归一”（perfection after many tries），数九寒天（coldest days of winter），“九牛一毛”（a drop in the ocean）。 Common words and idioms: Examples include “九九归一” (perfection after repeated effort), “数九寒天” (coldest period in winter), and “九牛一毛” (a drop in the ocean).
