封 🔊

网络内容摘要 (Web Content Summary):

• 核心含义：“封”是一个会意字，最初表示“以土筑堆、植树作界”，即以树木和土堆划定疆界、领地。 Core meaning: "封" is an ideogram originally meaning "to build an earthen mound and plant trees to mark boundaries or territories."

• 字形起源：甲骨文的“封”下方像土堆，上方为树木，形象地表现了古人用树和土作为分封、立界的做法。后来的字形逐渐演变，西周时期增加了“又”（表示手）符号，含义扩展。 Pictographic origin: In oracle bone script, the lower part depicts an earthen mound and the upper part a tree, reflecting the ancient practice of using trees and soil for territorial demarcation. Later scripts added the "hand" radical, gradually broadening the meaning.

• 常用词/易混点：现今“封”常用于“封信（to seal a letter）”、“封锁（to blockade）”、“封号（title/conferment）”等。与“丰”易混淆，两字古文中本为一体，今义不同。 Common uses/confusions: Today, "封" is seen in words like "封信" (to seal a letter), "封锁" (blockade), and "封号" (title or conferment). It is easily confused with "丰 (fēng)", as their ancient forms were related, but their modern meanings differ.

• 文化背景：“封”与古代分封制（如“分封诸侯”）密切相关，体现中国古代礼制与土地文化。 Cultural background: "封" relates to the ancient system of enfeoffment (such as granting fiefdoms to nobles), reflecting the land and ritual culture of early China.
