About
The character 洞 is structured with the water radical 氵 and the phonetic component 同, originally denoting water-filled cavities or caves. Its early usage centered on physical hollows, but over time its meaning expanded to convey ideas of penetration and thoroughness, as seen in derivatives like 洞穿 for piercing through or 洞悉 for perceiving clearly. The component 同 provides phonetic guidance while also implying a sense of passage or connectivity, reflecting the character's evolution from concrete to abstract applications.
