码

• Pinyin: mǎ
• Hanzi breakdown: 码 = 石 (stone) + 马 (horse/phonetic) — originally related to stone weights; extended to stacking and coding

Meaning

To stack or pile up systematically, especially bricks, goods, or written characters. Also a measure/code marker (号码 number, 密码 password).

As a verb, 码 appears in 码砖 (to lay bricks) and the internet slang 码字 (to type/write). As a noun element, it forms 号码, 密码, 条码 (barcode). The dual role makes it versatile across technical, colloquial, and internet contexts.

Examples

1. 工人们正在工地上码砖，动作娴熟而有节奏，一摞摞砖块整齐地堆放在地面上。 The workers were stacking bricks at the construction site with practiced, rhythmic movements, piling them neatly on the ground.
2. 他每天凌晨两点还在码字，为的是赶在截稿日期前完成这部长篇小说。 He’s still writing at two in the morning every day, trying to finish this long novel before the deadline.
