While both "student" and "pupil" refer to people learning, there's a subtle difference. Generally, "student" is a more common and widely used term for someone learning at any level, from primary school to university. "Pupil", on the other hand, is typically used for children who are learning at primary or elementary school. Think of it like this: a pupil is always a student, but a student isn't always a pupil.

Here are some example sentences to illustrate the difference:

• Sentence 1: He is a diligent student at university, working hard to achieve his degree.

• Translation: This sentence means that he studies hard and is dedicated to his university studies.

• Sentence 2: The teacher praised the pupil for their excellent work on the art project.

• Translation: This sentence means that the teacher commended the child's creative and well-executed project.

• Sentence 3: She is a bright student who excels in all her subjects.

• Translation: This sentence indicates that she is an intelligent student and does very well in all her classes.

• Sentence 4: The pupils were excited to learn about new topics in science class.

• Translation: This sentence means that the primary school students were enthusiastic to learn new scientific concepts.

Using the correct word shows a good understanding of English vocabulary and nuance. Choosing between "student" and "pupil" depends on the context and the age of the person you're describing. Remember, a pupil is usually younger than a student. Happy learning!
