Origin

The character 翁 combines a sound hint with a visual classifier. The top part 公 roughly indicates the pronunciation, while the bottom part 羽 means "feathers" or "wings" and serves as a classifier suggesting something bird-related or associated with movement and vitality. Over time, the feathers component came to represent the vigor and energy of an old man who still has life and spirit in him—not a feeble elder, but a venerable one worthy of respect. The character eventually settled into meaning a dignified, vigorous old man.
