About
The character 键 combines the metal radical 钅 on the left, indicating a metal object, with the phonetic component 建 (jiàn) on the right. Its traditional form 鍵 uses the full metal radical 金. Originally, 键 referred to the metal linchpin of a wheel hub or the bolt securing a door or gate. Since a pin or bolt is the single component holding an entire mechanism together, its meaning abstracted to signify the most crucial or pivotal element. In modern contexts, it also denotes the physical keys on pianos, typewriters, and computer keyboards.
