The Vietnamese word "dòi" primarily refers to a "silt bank," which is a natural formation of soil and sediment that builds up along a river or estuary. It can also mean a "promontory" or "headland," which are elevated pieces of land that extend into a body of water.
In a more advanced context, "dòi" can be used in discussions about ecology, geology, or geography. For example, you might discuss the role of silt banks in river ecosystems or their impact on local wildlife.
While "dòi" primarily refers to geographical features, in some contexts, it can also describe a situation where something is piling up or accumulating. However, this usage is less common and mostly context-specific.
"Dòi" is a useful term for discussing natural formations along rivers and coasts.
