About
The character 碇 is a phono-semantic compound combining the semantic stone radical 石 with the phonetic component 定, which itself conveys the idea of stability. Historically, it referred to heavy stones tied to ropes, which early sailors dropped into water to secure their vessels and prevent drifting. As nautical technology evolved and stone anchors were replaced by iron and steel ones, the character retained its meaning, shifting focus from the specific material to the functional purpose of the anchoring device. It remains a dedicated term in maritime vocabulary for securing a ship.
