An umbrella is a device used to protect oneself from the rain. It consists of several parts, including a RIB, COVER, SPOKE, and relet. The RIB is the curved metal or plastic piece that forms the frame of the umbrella. The COVER is the fabric that covers the frame and provides protection from the rain. The SPOKE is the thin rod that connects the RIB to the center of the umbrella. The relet is the small piece of fabric that attaches the SPOKE to the COVER. Finally, the SPOKE is the thin rod that runs along the circumference of the umbrella and helps to keep it open.
