About
The character "陔" is structured with the "阝" radical, denoting terrain or elevation, combined with the phonetic component "亥". Its etymology relates to steps or terraces on a hillside, reflecting the radical's association with landforms. Over time, its meaning shifted from physical terraces to abstract layers or tiers, as seen in classical texts where it refers to sections in music or levels in poetic descriptions of the heavens. The character's composition has not changed substantially, and its semantic expansion illustrates a transition from concrete topography to metaphorical stratification.
