An "edge" refers to the boundary or limit of an object or surface. It is the line where two surfaces meet, such as the edge of a table or the edge of a piece of paper. Edges can be sharp or smooth, and they play a crucial role in defining the shape and structure of various items. In a broader context, "edge" can also describe a competitive advantage in various fields, such as business or sports. For example, a company may have an edge over its competitors by offering better products or services, while an athlete might gain an edge through superior training or strategy.
