核心含义与起源：“码”是一个形声字，最初的繁体字为“碼”，由“石”作偏旁，表示与石头有关；声旁为“马”。在古代，“碼”本指“玛瑙”，即一种类似于玉的石头。Core meaning & origin: "码" (simplified form) is a phono-semantic character. Its traditional form is "碼," composed of the "石" (stone) radical and the "马" (horse) phonetic component. Originally, it referred to "玛瑙" (agate), a type of stone similar to jade.

现代含义：现在，“码”常用于表示“号码、编码”，如“密码”（password）、“号码”（number），以及计量单位“码”（yard，长度单位）。Modern meaning: Nowadays, “码” usually means "number" or "code," as in “密码” (password), “号码” (number), and is also used as a unit of measurement (yard).

• 易混点：“码”（number/code）和“玛”（agate，美玉）在现代汉语中意义不同。不应混淆。Easily confused: “码” (number/code) and “玛” (agate, a type of jade) have different meanings in modern Chinese and should not be confused.
• 常用词：如“二维码”（QR code）、“码头”（wharf, originally related to stone structures）。Common words: Examples include “二维码” (QR code), “码头” (wharf), the latter originally referring to a stone-built port.

文化小知识：“码”并非古老汉字，未见于《说文解字》，为后起字，多用作计数、标注之用。Cultural note: "码" is not found in ancient dictionaries like Shuowen Jiezi and is a later creation, mostly used for numbering and marking.
