Border lines are the boundaries that separate two different areas. The term can be broken down into three parts: HEMS (4 letters), EDGES (5 letters), and ENDS (4 letters). HEMS refers to the hemline of a garment, which is the line at the bottom of a skirt or dress. EDGES refer to the outermost limits of something, such as the edge of a cliff or the edge of a table. ENDS refer to the conclusion of something, such as the end of a book or the end of a journey. Together, these three words form the term BORDER LINES, which is used to describe the boundaries between two different areas.
