The Vietnamese word "kháp" generally means to join or fit together, often in a context where two parts are connected or matched precisely. It is frequently used in carpentry and construction to describe how pieces of wood or other materials fit into each other, such as in making furniture or structures.
In more advanced contexts, "kháp" can be used metaphorically to describe situations where two ideas or concepts are well aligned or complement each other. For instance, you might say that a plan "kháp" (fits well) with your goals, meaning it aligns perfectly.
While "kháp" primarily refers to the idea of fitting or joining, it can also imply a certain level of compatibility or harmony in various contexts, such as relationships or teamwork.
