The Vietnamese word "khô kháo" can be understood in a few ways, but it primarily relates to the idea of being dry or arid.
You can use "khô kháo" to describe situations where something is extremely dry, such as weather conditions or the state of the ground. It often conveys a sense of dryness that can affect travel or the condition of the environment.
In a more advanced context, "khô kháo" can be used metaphorically to describe a situation that feels barren or lacking in something essential, such as creativity or inspiration.
