纬 🔊

网络内容摘要 (Web Content Summary):

核心含义与字形来源：“纬”是一个形声字，最早见于战国时期的文字。左边的“糸”表示丝线，右边的“韦”既表示发音，也与绕行、缠绕有关。在古代，“纬”指织布时横向的丝线，即“纬线”（和“经线”相对），也可以引申指事物的横向维度。 Core meaning & origin: "纬" is a phono-semantic character, first seen in texts from the Warring States period. The left part "糸" means "silk thread", and the right part "韦" provides the pronunciation and also suggests the idea of winding or encircling. In ancient times, "纬" referred to the horizontal threads when weaving cloth—the weft (as opposed to "经", the warp)—and by extension, it can mean the horizontal aspect or dimension of things.

文化与有趣背景：“纬”中的“韦”本义为绕城一圈，引申出缠绕、环绕之意。这种含义与纺织时纬线横穿经线相互交织密切相关。 Cultural & interesting background: The element "韦" in "纬" originally meant to circle around a city, thus giving the extended meaning of winding or entwining, which relates closely to the way weft threads cross and intertwine with warp threads in weaving.

• 常见用法：“纬”常用在“经纬”（warp and weft, sometimes figuratively referring to the structure or coordinates of something），以及“纬度”（latitude, in geography, referring to horizontal lines on a map）。 Common usage: "纬" is often used in words like "经纬" (warp and weft, or the structure/coordinates of something), and "纬度" (latitude, in geography, referring to horizontal lines on a map).
• 易混淆点：“纬”易与“经”（warp, longitude）混淆，但“经”为纵向，表示长度方向；而“纬”为横向，表示宽度方向。 Common confusion: "纬" is easily confused with "经" ("warp" or "longitude"), but "经" refers to the vertical or lengthwise direction, while "纬" refers to the horizontal or widthwise direction.

成语和其他用法较少，有代表性的是“经天纬地”（形容有治理国家的卓越才干）。 Idioms and other uses are less common, but a representative one is "经天纬地", which describes someone with outstanding talent in governing or managing affairs.
