A "grader" is a machine used to level or smooth out a surface, such as a road or field. It has a large blade at the front that can be adjusted to different angles to cut into the ground or push dirt around. A grader is often seen on construction sites or in farming. It's important to note that a "grader" is not the same as a person who gives grades or marks on assignments, which is a different meaning of the word.
