专用
zhuānyòng · HSK 6
use for special purpose
🔒🔧 zhuan (special) + yong (use) = reserved for one purpose only
Think of a dedicated tool that only does one job. 专 means exclusive or special, 用 means use. Together they mean something set aside for a specific, dedicated purpose — like a reserved parking spot or a military-only channel.
用 — pictograph of a bucket or wooden pail
用 originally depicted a bucket or container, possibly a sacrificial vessel made of wood. Over time it was borrowed to mean 'to use' or 'employ,' losing its concrete object sense. The modern meaning 'use' has been standard since early classical Chinese.
