The Vietnamese word "rìa" is a noun that primarily means "edge" or "fringe." It refers to the outer part or border of something. You can think of it as the area that is furthest from the center or the main part of an object.
In more abstract contexts, "rìa" can refer to the outskirts or periphery of a situation, idea, or community. For example, you might say, "Anh ấy sống ở rìa thành phố." (He lives on the outskirts of the city.) This indicates that he lives in a less central area, away from the main urban activities.
While "rìa" primarily refers to an edge or fringe, it can also imply a boundary or limit in a figurative sense, such as the boundaries of a discussion or the limits of a situation.
