umbrella

An umbrella is a folding canopy supported by wooden or metal ribs that is mounted on a wooden, metal, or plastic pole. It is usually designed to protect a person against sun or rain. Initially[when?] they were used in warmer countries for shade from the sun, but in modern times they evolved to also be used for protection from rain. Etymologically, the term umbrella is to be used when protecting from the sun, but is also commonly used when protecting from rain. Some countries specifically use the words parasol and parapluie to differentiate based on their use. There are also combinations of parasol and parapluie that are called en-tout-cas. A modern hand-held umbrella or parasol may have a black exterior canopy and a silver inner coating, for better protection from both the sun and ultraviolet rays, and may be water-resistant.
