"Лужу" is a Russian word that translates to "puddle" in English. It refers to a small pool of water that forms on the ground, often after rain. Puddles can vary in size and depth, and they are commonly found on streets, sidewalks, and fields. They can be created by melting snow or ice as well. Puddles are important for the environment as they provide water for small animals and plants. They can also serve as habitats for various organisms, such as frogs and insects. Additionally, children often enjoy jumping in puddles for fun, making them a familiar sight in many neighborhoods.
