An umbrella is a portable device used to protect people from rain or sunlight. It consists of a circular canopy made of fabric, which is supported by a framework of ribs and a central pole. When opened, it creates a shield that keeps you dry during a downpour or provides shade on a sunny day. Most umbrellas are designed to be lightweight and easy to carry, making them a common accessory for many people. They come in various sizes, colors, and styles, allowing individuals to express their personality while staying protected from the elements.
