贰 🔊

网络内容摘要 (Web Content Summary):

贰（拼音：èr）本义为“二”，是数字2的大写，多用于正式场合或金融票据，以防数字被篡改。在古文字中，“贰”为形声字，从“贝”（与钱财相关），声旁为“弍”（古“二”字）。 贰 (pinyin: èr) means "two" and is the formal or complex form of the number 2, commonly used in financial documents to prevent tampering. It is a phono-semantic compound character, with "贝" (shell/money) as its radical and "弍" (an ancient form of "two") as its phonetic part.

• 象形与文化背景： “贝”表示与货币、价值相关；“弍”是“二”的古字形。古时在重要场合用“贰”防止数字被改动，体现对资金财产的重视。 Pictographic and Cultural Background: The "贝" component relates to money or value, while "弍" is an archaic form of "two." Traditionally, "贰" was used in important contexts to secure numerical integrity, highlighting the importance of protecting assets.
• 特别用法： “贰”常见于支票、账单等正式或金融文件中，与“一、叁（3）、肆（4）”等数字大写并列使用。容易与普通数字“二”混淆，需区分。 Special Usage: "贰" often appears in checks, invoices, and formal/financial documents, alongside other complex numerals like "壹"(1), "叁"(3), etc. It is sometimes confused with the regular "二", so care should be taken to distinguish them.
• 相关词语/成语： “贰心”意为二心、三心二意，有不专一、不忠诚的意思。“贰臣”指叛变过的臣子。 Related Words/Idioms: "贰心" (èr xīn) means to be double-hearted or disloyal; "贰臣" (èr chén) refers to a minister who has betrayed their loyalty.
