About
The character 闸 (zhá) is a phono-semantic compound that originally meant a water gate or sluice. Its traditional form 閘 is framed by the door radical 門 (mén), now simplified to 门, which indicates a barrier or opening that can be closed and opened. The phonetic component inside is 甲 (jiǎ). The term referred to a heavy drop-gate used in canals and rivers to manage water levels, control flooding, and aid navigation. This concept was later extended in modern usage to include mechanical brakes, electrical switches, and safety shutters.
