A "field" is an open area of land, often covered with grass or crops. It can be a place where farmers grow food, like wheat or corn, or where children play games like soccer. Fields are important for nature, providing habitats for animals and plants.
In a broader sense, a "field" can also refer to a specific area of study or work, such as science, art, or education. People often specialize in a field to gain expertise and contribute to that area. For example, a doctor works in the medical field, helping to keep people healthy.
