Explanation
A pupil is a young student who goes to school and learns from a teacher. For example, children sitting in a classroom and studying are called pupils. The word is also used for the small black circle in the center of your eye, which helps you see by letting light enter. This second meaning comes from an old idea of a “little person”, because when you look closely into someone’s eye, you can see a tiny image reflected there, like a small person. That is how the same word came to be used for the eye.
