About
The character "夼" is formed by the components "大" and "川", which convey the ideas of "large" and "river" respectively, resulting in an ideographic compound that originally denoted a substantial watercourse or landform. Its etymology directly informs its meaning as a ravine or gully, a specific topographic reference that has persisted through its usage, primarily in place names, without expanding into other semantic areas. Structurally, the arrangement of "大" above "川" has remained unchanged, visually emphasizing the concept of a large, river-like depression in the landscape.
