About
As a phono-semantic compound, 堠 combines the semantic earth radical 土 on the left with the phonetic component 侯 on the right. It originally denoted an earthen mound or small watchtower used for military observation and defense along borders. With the development of ancient courier systems, its meaning expanded to include mounds built at regular intervals along official roads as mile markers, aiding travel and distance calculation. Thus, 堠 reflects both a defensive structure and key infrastructure for navigation and state communication.
