The term "rare" refers to something that is not commonly found or encountered. For example, certain species of animals, like the Amur leopard, are considered rare because there are very few of them left in the wild. This scarcity makes them special and often leads to conservation efforts to protect their habitats. In everyday life, you might find rare items in collections, such as rare coins or vintage toys. These objects are sought after by collectors because they are hard to come by, making them valuable. The uniqueness of rare items often adds to their charm and allure, capturing the interest of many.
