About
械 is a phono-semantic compound combining the wood radical 木 and the phonetic component 戒. The 木 reflects the original wooden construction of the objects named, while 戒 (meaning 'to guard' or 'warn') supplies the sound and a connotation of defense or preparedness. The character initially designated wooden fetters or restraints for prisoners. Its meaning later broadened to tools, implements, and weapons, and eventually extended to modern machinery and mechanical devices, long after materials diversified beyond wood.
