Student

A student (also pupil) is a learner, or who attends an educational institution. In most nations, the English term (or its cognate in another language) is reserved for those who attend university, while a schoolchild under the age of eighteen is called a pupil in English (or an equivalent in other languages), although in the United States and in Australia a person enrolled in grades K–12 is often called a student. In its widest use, student is used for anyone who is learning, including mid-career adults who are taking vocational education or returning to university, or younger researchers or artists learning from a more experienced (and usually older) colleague and mentor.
